China has successfully established the world's first three-satellite constellation on the distant retrograde orbit (DRO) in the Earth-moon region of space, connecting them with stable inter-satellite measurement and communication links, Global Times learned from program developer the Chinese Academy of Sciences (CAS).  

Such development has yielded variety of original scientific and technology outcomes, laying a solid ground for the country's future development of the Earth-moon region of space and frontier exploration of the space science, the CAS disclosed in the statement it provided to the Global Times on Wednesday. 

Per the CAS, the Earth-moon region of space refers to the expanded domain extending outward from Earth's orbit, reaching up to 2 million kilometers from Earth. Compared to Earth's orbital space, its three-dimensional volume expands by more than a thousand times, the academy explained. 

Developing and utilizing cislunar space holds tremendous strategic significance for lunar resource exploitation, long-term human habitation beyond Earth, interplanetary activities, and the sustainable exploration of the solar system, it added. 

The CAS launched preliminary research and key technology development in this region in 2017. In February 2022, a pilot project was initiated to develop and launch three satellites to form a large-scale satellite constellation in the region of space, aimed at exploring the unique characteristics and application potential of the DRO.

The DRO-A and -B satellites were launched in March 2024, and entered their mission orbit on July 15 the same year, while the DRO-L was launched in February 2024 into a sun-synchronous orbit and began conducting experiments as planned. The three formed the constellation for the first time in August 2024. 

The plan included DRO-A satellite permanently staying in the DRO, while the DRO-B satellite operates in Earth-moon space maneuver orbits, according to CAS' Technology and Engineering Center for Space Utilization (CSU.)

Chinese scientists have made significant breakthroughs in ranging fields since the set-up of the three-satellite constellation in 2024.

Building on years of research in Earth-moon region of space astrodynamics and space exploration, the scientific team proposed an innovative design concept: trading longer flight time for increased payload capacity and greater contingency margin. As a result, the satellites completed Earth-moon transfer and achieved low-energy DRO insertion using only one-fifth of the fuel required by traditional methods, marking the world's first successful low-energy insertion into a DRO. 

This breakthrough significantly reduces the cost of accessing cislunar space, opening up new avenues for large-scale development and utilization.

The team also achieved another world-first by successfully verifying a 1.17-million-kilometer K-band inter-satellite microwave measurement and communication link, overcoming a major technological bottleneck in building large-scale constellations in cislunar space. 

In terms of space science, the mission has also supported astrophysical research such as gamma-ray burst detection and trialed new technologies, including operating atomic clocks.

Moreover, Chinese researchers successfully validated a new space-based orbit determination system whereby one satellite tracks another, replacing traditional ground-based tracking. Using just three hours of inter-satellite measurement data, they achieved orbit determination accuracy equivalent to over two days of traditional ground tracking. This breakthrough significantly lowers the cost of orbit determination for cislunar spacecraft, paving the way for more efficient operations.

Wang Wenbin, a researcher at CSU, hailed that this achievement marks the first time internationally that orbit determination was verified using satellite-to-satellite tracking rather than ground stations. 

"It's like turning a traditional ground station into a satellite and placing it in a low-Earth orbit," he explained. "This opens a new technical pathway for China's future cislunar and deep space exploration. It also provides an efficient solution for orbit determination, navigation, and timing across various cislunar orbits, supporting the future expansion of large-scale commercial activity in cislunar space."

Researchers told the Global Times on Wednesday that the program would support China's future lunar exploration mission, including providing space-based inter-satellite measurement for rapid orbit determination and autonomous navigation services for lunar exploration mission orbiters, and supply high-precision time signals for lunar surface facilities. 

Additionally, as the DRO is far from Earth and the moon, free from obstructions, it could facilitate the establishment of communication links with lunar exploration mission spacecraft, and assist in the downlink of critical or emergency data, researchers explained.

Telcos ordered to resolve Internet issues

 TAPAH: Communic ations Minister Datuk Fahmi Fadzil has given all telecommunication companies until 5 pm on Sunday to submit solutions to the problem of poor Internet access nationwide, or face stern action.

Fahmi said he has contacted Malaysian Communications and Multimedia Commission (MCMC) executive chairman Tan Sri Mohamad Salim Fateh Din on Sunday morning and instructed telecommunications companies involved to respond promptly to the weak coverage feedback conveyed.

“Telecommunication companies need to be more proactive in resolving this issue. When it comes to collecting overdue bills, they’re lightning fast, but when we lodge complaints, it takes months.

“So I’ve had enough. If they fail to present swift and concrete solutions by 5 pm today, MCMC will begin enforcement action against them tomorrow,” he told reporters after visiting the National Information Dissemination Centre (NADI) in Air Kuning on Sunday.

Also present were Perak Communications, Multimedia and Non-Governmental Organisation (NGO) Committee chairman Mohd Azlan Helmi and Barisan Nasional candidate for the Ayer Kuning state byelection, Dr Mohamad Yusri

Bakir.

Fahmi said based on a drive test conducted by MCMC on March 5, many areas still fail to meet the Mandatory Standards on Quality of Service (MSQoS), which currently requires a minimum speed of 7.5 Mbps, which will be increased to 10 Mbps next year.

“The issue of Internet access is not only limited to Air Kuning, it is also affecting many other areas such as Belaga and Ulu Rajang in Sarawak, the new township of Serenia, the outskirts of Tambun, and even on Pangkor Island. Several Orang Asli villages have also been impacted,” he said.

He added that if the telecommunication companies failed to resolve the Internet access problem, they would face stricter enforcement measures, including hefty fines and penalties that could reach millions of ringgit.

“After we amended the Communications and Multimedia Act, which came into effect on Feb 11, fines and compounds that can be imposed on telcos will be significantly higher than before,” he said.

At the same time, Fahmi reminded netizens to be cautious when making statements or campaigning on social media, especially concerning the 3R issues (race, religion, royalty) during the Ayer Kuning byelection period.

“If there are individuals who upload extreme posts or 3R-related content, and are convicted in court, they may be fined up to RM500,000, compounded up to RM250,000, or face imprisonment. I hope all parties will conduct their campaigns in a responsible manner,” he said.

Fahmi said so far, no complaints have been received, but he expected campaign activities to pick up in the coming week.

When asked about Perikatan Nasional (PN) supporters using caricatures that seemingly mocked Prime Minister Datuk Seri Anwar Ibrahim and DAP secretary-general Anthony Loke, Fahmi said he was not surprised by the approach.

“If that’s how they want to campaign, so be it. That’s their way. Let us campaign based on facts, ideas, and what we can actually offer, not just insults and ridicule,” he said.- The Borneo Post (Sabah)

Beijing: We have ‘will and means’ to counter tariffs

ation: Liu Rui/GT -

BEIJING: China has called on the United States to remove unilateral tariffs as quickly as possible and work with it in the spirit of mutual respect, peaceful coexistence and win-win cooperation, in order to address respective concerns through dialogue and consultations on an equal footing, the Commerce Ministry says.

Chinese officials said on Wednesday that should Washington further intensify tariffs and restrictive measures against China, Beijing has the “firm will and abundant means” to fight until the end.

Their comments came after the State Council Information Office released on Wednesday a white paper titled China’s Position on Some Issues Concerning China-US Economic and Trade Relations, which noted that the recent US move of using tariffs as a coercive tool is a grave mistake and further exposes the typical unilateralist and bullying nature of the US government.

Since US President Donald Trump took office in late January, Washington has repeatedly imposed additional tariffs on China, and the tax rate on Chinese imports has now reached over 120%.

Noting that these actions could have a severe impact on China-US economic and trade relations, the white paper emphasised that the key is to respect each other’s core interests and major concerns and find proper solutions through dialogue and consultation.

The essence of China-US economic and trade relations is one of mutual benefit and win-win cooperation, despite the inevitable differences and friction that arise between the two countries due to their different stages of development and distinct economic systems, according to the document.

Trade data from the United Nations shows that the value of US goods exported to China reached US$143.55bil last year, up 648.4% compared with the US$19.18bil recorded in 2001.

The growth in US exports to China has far outpaced the 183.1% increase in overall US exports during the same period.

Detailing the white paper, a Commerce Ministry official said, “With firm will and abundant means, China will resolutely take countermeasures and fight until the end if the United States insists on further escalating economic and trade-restrictive measures.”

There is no winner in a trade war, and China does not want a trade war, the official emphasised, adding that the Chinese government “will by no means stand idle when the legitimate rights and interests of its people are being hurt and deprived”.

The official said that it is a typical act of unilateralism, protectionism and economic bullying for the United States to take tariffs as a weapon of exerting maximum pressure and pursuing self-interest.

Under the guise of pursuing “reciprocity” and “fairness”, the United States is engaging in zero-sum games and, in essence, seeking “America First” and “American exceptionalism”, the official said.

The United States is exploiting tariffs to subvert the existing international economic and trade order, prioritising US interests above the global common good, and sacrificing the legitimate interests of countries worldwide to serve its own hegemonic agenda, he added.

Noting that the United States is also deliberately severing the well-established global industrial and supply chains and breaking market-oriented free trade rules, the official said these practices seriously interrupt the economic development of countries around the globe and affect the long-term stable growth of the world economy.

Lin Jian, a spokesman for the Foreign Ministry, said at a daily news conference on Wednesday that “if the United States disregards the interests of the two countries and the international community and stubbornly persists in the tariff war and trade war, China stands ready to fight to the end”.

Cui Fan, a professor of international trade at the University of International Business and Economics in Beijing, said, “A trade war, for sure, produces no winner, but the United States is destined to suffer greater losses than others.”

On Tuesday, Goldman Sachs raised the odds of a recession in the United States to 45%, just a week after it said the odds were at 35%, as fears of an impending trade war increased.

It also revised its forecast for this year’s gross domestic product growth in the United States to 1.3%, down from 1.5% and cautioned about the possibility of a bear market.

Cui said the US tariff hikes will estrange allies, disrupt market dynamics, and provoke retaliatory actions that will reverberate throughout supply chains and hit US consumers hard.

More importantly, the measures fail to provide a clear path for the United States to regain its competitive edge in key industries, he added.

Navin Girishankar, president of the Economic Security and Technology Department at the Centre for Strategic and International Studies, said, “You can’t fight a trade war and then expect to win a tech war.”

Highlighting industries such as semiconductors, artificial intelligence and clean energy that largely rely on international collaboration, Girishankar said that tariffs would increase costs and reduce efficiency, eroding the ability of the United States bto compete in such sectors. — China Daily/ANN

  PETALING JAYA: From run-down facilities and dirty walkways to allegations of misused management funds, the issue of poor property and building management continues to plague stratified homes in Malaysia.

With the government now mulling changes to property and building management laws, stakeholders say the focus should be on improving enforcement by the commissioner of buildings (CoB).

The new laws must improve and mandate the CoB to enforce laws under the Strata Management Act (SMA) 2013, said Datuk Theng Book, chairman of the Strata Owners Association Malaysia.

“There’s been a serious lack of enforcement by CoBs. In most cases, they will pass the buck back to management bodies.

“Management corporations (MCs) and joint management committees (JMCs) do not have the authority to enforce the laws,” he said.

This then usually leads to long-drawn-out and expensive civil court cases, he said.

Theng said the new laws must also clarify how MCs or JMCs can use maintenance funds, and standardise maintenance fee rates in the growing trend of mixed development stratified projects.

“The maintenance fee rates for residential and commercial tenants can vary wildly from project to project,” he said.

Michelle Lai, director of property management company Auntie Michelle Resources (M) Sdn Bhd, says the problem is also due to a lack of standardised enforcement and training in the industry.

“There is no consistency as different management offices enforce different rules which leads to confusion, especially for owners and investors who have units in different buildings,” said Lai.

“Many JMCs are not professionally trained and lack the capacity to manage buildings properly.”

She added that new laws should have CoBs demanding greater accountability and professionalism from JMCs and MCs.

“CoBs can perform regular transparent audits of management bodies and set clear enforcement standard operating procedures.

“They should also conduct perio­dic on-site inspections to assess building safety, especially for ageing properties.

“In addition, there must be a mandatory guideline for sche­duled refurbishment and main­tenance of property,” she added.

Malaysian Institute of Property and Facility Managers president Ishak Ismail said any new pro­perty management laws must provide more enforcement mechanisms for management bodies.

On Tuesday, Housing and Local Government Minister Nga Kor Ming announced that new laws may be formulated to overcome the issue of poor management of stratified homes.

He said there was a shortage of licensed property management firms in Malaysia, with only 594 licensed firms serving 26,334 strata schemes or 2.9 million units of Malaysian strata properties.

This has led to a rise in unlicensed and unqualified property managers

America First’ cannot deprive other nations of development rights

On Wednesday, the US implemented higher tariffs on nearly 60 trade partners, including a 104 percent tariff on goods from China. This is undoubtedly a serious provocation to the world trade system and a direct blow to the stability of global industrial supply chains. In response, a Chinese Foreign Ministry spokesperson stated that the Chinese people's legitimate right to development cannot be deprived, and China's sovereignty, security and development interests are inviolable. On the same day, the Chinese government released the white paper, "China's Position on Some Issues Concerning China-US Economic, Trade Relations." The document points out that the rise of unilateralism and protectionism in the US has significantly impeded the course of normal economic and trade cooperation between the two countries. It criticizes the US for imposing trade restrictions, such as tariffs, under the banner of "America First." The US policy of unilateralism is not only a blatant infringement on the development rights of other nations but also a selfish and short-sighted approach that will ultimately backfire.

Development is a common pursuit of humanity and a fundamental right recognized by the United Nations Charter and the Universal Declaration of Human Rights. All countries and peoples should have equal rights to improve their economic and social conditions and raise the standard of living, with no hierarchy of priority. As the world's largest economy, the US has long benefited from the trade rules, yet when faced with its own structural economic issues, it chooses to shift the burden onto other countries. This is extremely selfish and irresponsible. The logic behind "America First" is rooted in unilateralism and power politics, attempting to reshape the rules of globalization through tariffs, technology blocks, and industrial decoupling. In essence, it is a crude violation and systematic deprivation of the universal development rights of all nations.

The most-favored-nation principle and bound tariffs commitments under the World Trade Organization (WTO) are cornerstones of the multilateral trading system that was initially led and shaped by the US. They also serve as crucial institutional safeguards for developing countries to achieve fair development rights. Multiple assessments have found that tariffs have dealt particularly heavy blows to developing countries, especially many of the least developed nations. Ensuring the stability and strong resilience of the supply chain is a necessary condition for the economic development of many countries, and foreign trade is an important way for a country to integrate into the process of globalization. However, the US is now preemptively setting up "gates" and "toll booths" along this path, even attempting to monopolize and manipulate other countries' development rights. This represents not only a regression in history, but also a betrayal of humanity's shared values.

The US unilateralism actions have already provoked widespread international countermeasures. Facing the unreasonable "reciprocal tariffs" imposed by the US, China firmly retaliates. It announced the additional tariffs on products imported from the US to 84 percent, effective from 12:01 pm Thursday, fulfilling its promise to "continue to the end" and demonstrating its commitment to defending the multilateral trade system. On Wednesday, a majority of the EU's 27 member states voted in favor of the counter-tariffs of 25 percent to hit around 21 billion euros ($23.2 billion) of US goods in retaliation for the duties imposed by the US last month on EU's steel and aluminum exports. Canada also declared its retaliatory 25 percent tariffs on vehicles imported from the US starting Wednesday. It is evident that even traditional allies are unwilling to foot the bill for "America First." This growing divergence reveals a hard truth: An "America First" approach that undermines globalization won't gain broad recognition and support from the international community. It will only lead to deeper isolation for the US, and the decline of its international credibility and moral standing will be inevitable.

Washington fantasizes about reshaping the global economic landscape through enacting tariff barriers, yet it underestimates its own dependence on global supply chains and the resilience of other countries' economies. Ironically, the "America First" policy has primarily undermined the development rights of the American people. High tariff policies have led to increased costs for US imported raw materials, which not only fail to revitalize the manufacturing sector but also result in shrinking profits or even large-scale bankruptcy for small and medium-sized enterprises. A study by the US-China Business Council finds that in the three years following 2018, the US lost approximately 245,000 jobs due to the trade war. "America First" cannot take away the development rights of other countries; it can only become synonymous with "self-inflicted consequences."

What we need in today's world is justice, not hegemony. Justice means respecting the development rights of all countries and resolving differences through dialogue within the framework of the WTO. The US, under the guise of "reciprocity," is actually implementing an "America First" policy, which not only cannot deprive other countries of their development rights but also exposes the shortsightedness of unilateralism and highlights the necessity of global cooperation. By cooperating to counter the "America First" policy, which goes against the historical trend, as well as firmly opposing various unilateral actions that challenge international consensus, the international community can better uphold the fair development rights of all countries and truly achieve shared prosperity. - Global Times editorial

Crypto ownership surges among youths

SINGAPORE: More people in Singapore own cryptocurrencies and younger users among them are leading the way in using the asset for daily financial needs, such as online shopping and bill payments, a new study shows.

The number of Singapore residents who own cryptocurrencies is on the rise, with 26% of them owning digital assets in 2024, up from 24.4% in 2023.

Of those who hold crypto, a majority, or 52% of them, have paid for goods and services with it, and 67% of them plan to increase usage of crypto for payments in the future.

Gen Zs and millennials, or those aged between 16 and 44 years old as at 2025, lead in crypto ownership, with about 40% of them holding crypto.

Of this group of people, 41.1% of them use crypto for online shopping, 35.9% for bill payments and 27% for in-store retail goods.

While younger consumers use crypto to pay for retail goods and bills, the older generation – those aged 45 or older in 2025 – uses crypto more for peer-to-peer (P2P) transactions such as those made between friends and family.

Among the older generation of crypto users, 42.9% of them use crypto for P2P transactions, followed by 35.7% for online shopping and 17.2% for bill payments.

These were some of the findings from the study by Singapore-based crypto payments firm Triple-A, based on a survey of 1,006 residents in Singapore.

Singapore has seen a notable increase in crypto payments, with merchant services receiving nearly US$1bil (S$1.3bil) in crypto in the second quarter of 2024, much higher than any other quarter in the past two years, according to data from blockchain analysis firm Chainalysis.

A separate Chainalysis report in September 2024 noted a growing adoption of crypto as a payment method in Singapore.

“The combination of regulatory clarity and merchant adoption suggests that Singapore is positioning itself as a major hub for digital assets, which could eventually attract more global businesses and investors,” Chainalysis said.

AXS, in partnership with Triple-A, allows its app users to make top-ups or pay bills in digital currencies such as bitcoin, ethereum, USD coin and tether. Other merchants that have partnered Triple-A to offer the crypto payment option include fashion brand Charles & Keith on its eCommerce platform and Apple products reseller iStudio at its retail stores.

The findings from Triple-A also noted that 37% of respondents cited global acceptance as a key benefit of crypto payments.

Higher transaction speed (29%) and lower fees (20%) were also important factors, particularly for cross-border and time-sensitive transactions. But there are concerns about the crypto ecosystem.

The complexity involved in using crypto was the top challenge cited by 63% of respondents. For instance, users need to figure out the use of private keys, or passwords that allow them to access and manage their crypto funds.

Security concerns (60%) and lack of merchant acceptance (54%) were also factors of concern.

The crypto payments trend comes against a backdrop of a rising number of digital payment token (DPT) firms being licensed by the Monetary Authority of Singapore (MAS), fuelling new roles in the growing Web3 industry.

Web3 companies are those that use blockchain technology to build products and services.

As at end-November 2024, MAS had issued a record 13 new DPT licences in 2024, raising the total number of DPT licensees from 16 to 29, a report from blockchain intelligence firm TRM Labs released in December 2024 said.

Despite a global slowdown in hiring with mass layoffs in 2024, more than 75% of local Web3 companies want to expand their workforce in 2025 as they continue developing products and services for global and regional markets.

This is according to a report led by the Singapore FinTech Association (SFA), Web3 business account platform HQ.xyz as well as Web3 builder communities SG Builders and Superteam, which conducted surveys and case studies with 53 Web3 companies.

Of these companies, 60% are looking to expand their current workforce by half or more, the report said.

SFA, which facilitates collaboration between market participants and stakeholders in the fintech ecosystem, told The Straits Times that the hiring plans are driven by growing institutional adoption, ongoing technology improvements in blockchain, and the expansion of applications for Web3 technology.

Moves that increased institutional adoption of digital assets include the US Securities and Exchange Commission approving the first US spot bitcoin exchange-traded funds launched by Blackrock, Fidelity and others in January 2024.

A total of 2,433 individuals are currently employed in the local Web3 sector, excluding those working in Web3 roles in non-Web3 native firms.

These roles include those in partnerships, marketing strategy, and sales to help Web3 companies go to market with their solutions, said SFA.

Product managers as well as developers and software engineers are also key roles being hired.

“We also see jobs being created in the professional services sector that support Web3, which include legal, advisory, and consulting roles,” SFA said.

Companies also outlined what they hope to see improvements on as the acceptance of Web3 grows in Singapore. — The Straits Times/ANN
