China's Guizhou eyes strategic ties with Sabah

Published on: Thursday, July 24, 2025 Published on: Thu, Jul 24, 2025 Text Size: Liew (first right) in discussion with Liu Baochang and Datuk Frankie Liew. Kota Kinabalu: A delegation from the Guizhou Provincial Foreign Affairs Office visited Sabah on Tuesday with the aim of establishing a friendly provincial-state relationship with Sabah, marking a potential new chapter in bilateral cooperation between China's Guizhou Province and the Malaysian state. The proposal, which centres on strengthening ties in economy, culture, trade, tourism and people-to-people exchanges, was well-received by State Minister of Tourism, Culture and Environment, Datuk Seri Christina Liew, and State Minister of Industrial Development and Entrepreneurship, Datuk Phoong Jin Zhe. The visit, facilitated by the Sabah China Chamber of Commerce (SCCC), saw the Guizhou delegation pay courtesy calls to both ministers to present the province's vision for collaboration. Leading the delegation, Deputy Director-General Liu Baochang outlined Guizhou's strengths, including its status as a hub for new energy, computing power infrastructure, scientific innovation, and liquor production, as well as being home to tech giants like Apple and Huawei, and the globally renowned 500-metre Aperture Spherical Radio Telescope, 'Sky Eye'. He said Guizhou is now actively expanding its reach to Central, South, and Southeast Asia, and sees Sabah as a strategic partner in the region. Liu also extended an invitation for Sabah leaders to visit Guizhou and witness firsthand the province's industrial and technological advancements. 'We hope to deepen and broaden cooperation in economic, cultural, and tourism fields, and establish a formal friendly relationship between our two governments,' Liu said. Christina welcomed the initiative, describing it as an opportunity to connect with one of China's dynamic provinces. 'This visit opens doors for greater understanding and collaboration, especially in areas like eco-tourism and the Malaysia My Second Home (MM2H) programme,' she said. She introduced Sabah's strengths in sustainable tourism, its rich biodiversity, and ongoing efforts to preserve indigenous cultures. She also revealed plans for a 65-acre Cultural Centre in Kinolok, where all 35 indigenous ethnic groups in Sabah will showcase their heritage, further enriching the state's tourism appeal. Meanwhile, Phoong highlighted Sabah's push toward industrialisation and infrastructure development, citing upcoming projects like the Pan Borneo Highway, airport expansions in Kota Kinabalu and Tawau, and the upgrading of Sepangar Port. 'Sabah is undergoing transformation through innovation and infrastructure. We see Guizhou as a valuable partner in this journey,' said Phoong, who also invited the delegation to participate in the 2nd Sabah-China Expo this November. He added that the state is working towards increasing its power supply by 700 megawatts by 2030, including launching Malaysia's first wind power plant. Datuk Frankie Liew, President of the SCCC, praised the high-level composition of the Guizhou delegation, which includes senior officials from the foreign affairs office, commerce department, and municipal governments. 'Sabah and Guizhou share similarities in natural resources and cultural heritage. With strong will from both sides, I believe we can foster pragmatic cooperation,' he said. He noted strong potential in areas such as ecological protection, creative industries, environmental technology, and green development, expressing confidence that the partnership would spur mutual growth. Also present during the visit were SCCC Deputy President Brett Chua, Vice President Ir. Ts. KJ Tan, JP, Datuk Jonathan Koh, JP, and officials from Invest Sabah including CEO Dr. Firdausi Suffian. The visit is seen as a stepping stone toward building a long-term cooperative relationship between Guizhou and Sabah, paving the way for increased economic opportunities and cultural exchange between the two regions. * Follow us on our official WhatsApp channel and Telegram for breaking news alerts and key updates! * Do you have access to the Daily Express e-paper and online exclusive news?

CNBC's The China Connection newsletter: Beijing has more to worry about than just deflation

China's economy requires more than short-term stimulus, even as deflationary pressures intensify. That's the message from economists, including those at the highly ranked Peking University's Guanghua School of Management. Academics at Beijing's top schools often share recommendations with policymakers. It's not that the persistent drop in prices should be overlooked, but that they're signaling the need for more serious changes — just as China prepares its "15th five-year plan." It's a national social and economic development blueprint for the period from 2026 to 2030. China is wrapping up its 14th such plan this year and is expected to reveal details for the next five years in the coming months. "When we talk about the 15th five-year plan, the key issue is how to grow productivity," Liu Qiao, dean of the Guanghua School and a finance professor, told me last week. He's referring specifically to "total factor productivity," a measure of an economy's productivity gains from technology, innovation, economies of scale, or policies, without adding more labor or capital. According to the International Monetary Fund, China's total TFP growth fell from 4.1% in the 2000s to 2.6% in the 2010s, and entered a state of decline from 2006. Liu believes China's TFP needs to grow by at least 2% or more. To that end, tech innovation is an important part of the upcoming five-year plan, Liu said. But he added that institutional reform is just as important. The Chinese Communist Party's grip on the state and its institutions enables it to exert greater influence over the economy than in the U.S., for example. "80% of China's total factor productivity comes from institutional reform," economist Zhou Tianyong wrote in an opinion piece in Chinese business news magazine Caixin, which CNBC translated. Zhou is a former vice president of the International Strategy Institute at the Central Party School, China's higher education institution for training party leaders. Zhou pointed out that the textbook definition of technology as a way to boost productivity doesn't necessarily apply in China, where business and consumer interests are constrained in certain areas. "Without economic system reform, there will be no medium-to-high-speed growth." All this may seem rather academic for the average markets discussion more focused on deflation, industrial overcapacity and spillover into trade tensions. But public debate is limited in China. In a country where leaders operate by building consensus behind closed doors, policy signals come largely from key phrases in government documents and high-level speeches. One of those signals has emerged in just the last few weeks. Chinese President Xi Jinping led a high-level financial and economic commission meeting on July 1, which called for improving government officials' understanding of how their performance is evaluated, according to a state media readout. "Routine assessments [of officials] cannot only focus on how much GDP has grown and the number of major projects, but also on how much debt is owed," Xi said at another high-level meeting this month that focused on urban development. The current system for evaluating the performance of government officials has also inadvertently contributed to China's overcapacity issues, where industries are producing more goods than the market can absorb, according to Goldman Sachs. Local authorities are incentivised to collect revenue even if manufacturers are losing money under the current production-based tax system, Goldman Sachs Chief China Economist Hui Shan said in a report Monday. "Solving overcapacity issues requires a different incentive structure for local officials' evaluation and promotion," she added. "None of these fundamental adjustments will be easy or quick to implement." As China's economic growth slowed over the last several years, Beijing has emphasized the need for "high-quality" development. But the country still makes a big deal out of its annual GDP target, which is 5% this year. Looking ahead, China will likely signal a lower growth target around 4.5% to 5%, Guanghua's Liu said. But what's more important in his view is that local authorities may then be able to focus more on consumption, rather than investments, which have contributed to overcapacity issues. Policymakers will likely also try to reduce the gap in urban and rural income — or "common prosperity" — which can increase support for 255 million people and help boost consumption, Liu said. But in the near term, the economy probably needs a little more stimulus, such as a cash transfer, he said. Chinese authorities have stepped up plans to further support employment and improve social welfare. But policymakers have so far avoided the mass cash handouts that the U.S. and Hong Kong gave residents to stimulate spending after the pandemic. In a packed month for policymakers, senior party members are also expected to hold a Politburo meeting to discuss the economy by the end of the month. But analysts don't have high expectations. With the first half of the year in the books, the scale of stimulus is pretty much already set, and policymakers are now turning their attention to the next five years, said Zong Liang, former chief researcher at the Bank of China. He expects policymakers to prioritize consumption over investment, and tilt the balance toward the interests of businesses, noting the state has played a larger role in the past five years. But he cautioned that Beijing would remain wary of the risks that could arise from relaxing too much control. Old habits may die hard. Trina Chen, co-head of China equity research at Goldman Sachs, discussed China's efforts to manage overcapacity in key sectors like solar, steel and lithium. Yang Liu, CIO and chairman of Atlantis Investment Management, said that negative views on China's economy ignore the country's strengths in artificial intelligence and supply chains. David Autor, labor economist at MIT, said that the U.S. has not "fully come to grips" with the nature of the challenge it faces from China. China is going after excessive discounts. Premier Li Qiang last week called for more regulatory oversight of the electric car price war. The market regulator later stated on Friday that it had met with Meituan, and Alibaba's Eleme, and called on them to compete rationally. U.S.-China trade truce set for extension. U.S. Treasury Secretary Scott Bessent said Tuesday he is likely to hash out an extension of President Donald Trump's upcoming trade deadline with China when he meets with his Chinese counterparts in Stockholm next week. Economic uncertainty persists. China kept its benchmark lending rates steady on Monday as the country continues to grapple with weak consumer sentiment and softening growth. But the country's affluent are feeling just as poorly about the economy as they did during the pandemic, according to consulting firm Oliver Wyman. Mainland China and Hong Kong stocks rose on Wednesday amid a broader rise in the region, after U.S. President Donald Trump announced that he had completed a "massive Deal" with Japan, which set tariffs of 15% on the country's exports to the U.S. Mainland China's CSI 300 was up 0.02% while Hong Kong's Hang Seng Index — which includes major Chinese companies — had gained 1.27% as of 3:30 p.m. local time (3:30 a.m. ET). The Hang Seng Tech Index, which tracks the largest technology companies listed in Hong Kong, rose 2.14%. The mainland benchmark is up around 4.7% year to date, data from LSEG showed. July 24: European Commission President Ursula von der Leyen is slated to meet with Chinese President Xi Jinping during a visit to Beijing July 26 - 28: World Artificial Intelligence Conference in Shanghai Next week: U.S. Treasury Secretary Scott Bessent is scheduled to meet his Chinese counterparts next week in Stockholm Politburo meeting expected by the end of the month

Many lung cancers are now in non-smokers. Scientists want to know why

'My family needs me,' she recalled thinking. Chen's case represents a confounding reality for doctors who study and treat lung cancer, the deadliest cancer in the United States. The disease's incidence and death rates have dropped over the last few decades, thanks largely to a decline in cigarette use, but lung cancers unrelated to smoking have persisted. The thinking used to be that smoking was 'almost the only cause of lung cancer', said Dr Maria Teresa Landi, a senior investigator at the National Cancer Institute, which is part of the National Institutes of Health. However, worldwide roughly 10% to 25% of lung cancers now occur in people who have never smoked. Among certain groups of Asian and Asian American women, that share is estimated to be 50% or more. These cancers are increasingly drawing the attention of researchers like Landi, who are studying the role that environmental exposures, genetic mutations, or other risk factors might play. They have already found some early hints, including a clear link to air pollution. Physicians are also testing new approaches to better detect lung cancer in non-smokers. They are trying to understand why it is more prevalent: in people of Asian ancestry; in women; and why it is being seen among younger people. 'We all still think about the Marlboro man as what lung cancer looks like,' said Dr Heather Wakelee, chief of oncology at the Stanford University School of Medicine. In many cases, though, that's no longer true. 'We're just baffled as to why,' she said. Looking for Clues Many lung cancers in non-smokers have no known cause and are discovered only by chance. That was the case for Sandra Liu, 59, who lives in New Jersey. Liu was diagnosed this year with adenocarcinoma, the most common type of lung cancer among non-smokers. Doctors found the mass after she had a full-body check-up during a visit to China — a process popular with some Chinese expatriates visiting the country that includes a chest scan. 'I would have never thought to go for a CT,' she said, noting she had no major symptoms and never smoked. Scientists are starting to see that the biology of cancer in non-smokers like Liu differs from cancers seen in people with a smoking history — and may require different strategies for prevention and detection. One large study, called 'Sherlock Lung' and led by Landi and colleagues at the University of California, San Diego, is looking at the mutational signatures, or patterns of mutations across the cancer genomes, of 871 non-smokers with lung cancer from around the world. Their latest findings, published in Nature this month, showed that certain mutations, or changes to DNA, were much more common in people who lived in areas with high amounts of air pollution — for example, Hong Kong, Taiwan, and Uzbekistan. More pollution was linked to more mutations. The study did not include data from India, considered to have the highest levels of outdoor pollution. The researchers didn't just find that pollution may directly damage DNA. They also saw signs that pollution causes cells to divide more rapidly, which further increases the likelihood of cancer. Studies have also shown that people who don't smoke but have a family history of lung cancer, such as Chen and Liu — both of Liu's grandfathers had the disease — are at increased risk. This could be because of shared genetics, a common environment or both, said Dr Jae Kim, chief of thoracic surgery at City of Hope in Duarte, California. And scientists know that non-smokers with lung cancer are more likely than people who smoked to have certain kinds of 'driver' mutations, changes to the genome that can cause cancer and drive its spread, Kim said. In contrast, people who smoke tend to accumulate many mutations over time that can eventually lead to cancer. This difference in the type of mutations may be one reason why lung cancer among people under-50 is more prevalent among nonsmokers than smokers. Leah Phillips at her home in Peewee Valley, Kentucky. Photo / Jon Cherry, the New York Times There are probably other factors, too, including exposure to radon, asbestos and possibly aristolochic acid, a compound once common in traditional Chinese medicine. Landi's research linked the compound to lung cancer mutations among Taiwanese patients. Taiwan banned products containing it in 2003. Studies from Asia have also suggested second-hand smoke, fumes from cooking oils, and a history of tuberculosis or other lung disease as possible culprits. However, these potential contributors are less common in the US, where Asian American women who don't smoke are still nearly twice as likely as other women to be diagnosed with the disease, said Scarlett Gomez, a professor of epidemiology and biostatistics at the University of California, San Francisco. To understand what's driving the disparity in the US, Gomez, Wakelee and colleagues at other Northern California institutions are now studying the relationships among genes, environmental contaminants and lung cancer in Asian American non-smoking women. 'Ultimately, we want to be able to come up with actionable risk factors, just like we do for breast cancer and colorectal cancer,' Gomez said. Revisiting Screening Guidance Studies like Gomez's may help address the question of who should be screened for lung cancer. In the US, routine screening is recommended only for people aged 50 to 80 who smoked at least the equivalent of one pack of cigarettes per day for 20 years. Because of that, lung cancer in non-smokers is often not caught until it's advanced, said Dr Elaine Shum, an oncologist at NYU Langone Health. That can have devastating consequences for patients like Chen, who is still undergoing treatment after a third metastasis of her cancer. Shum and others are now exploring whether screening should be expanded. In Taiwan, a nationwide trial tested the effectiveness of CT scans in people aged 55 to 75 who never smoked but had one other risk factor. Doctors detected cancer in 2.6% of patients — enough that Taiwan now offers routine screening for non-smokers with a family history of lung cancer. Shum and colleagues recently ran a similar pilot study among women of Asian ancestry who were 40 to 74 and had never smoked. In preliminary results from about 200 patients, they found invasive cancer at comparable rates to the Taiwan study. Data from the full set of 1000 patients who were screened is forthcoming. Still, it would take far more research to determine who in the US, if anyone, would benefit from broader screening and whether it could meaningfully reduce lung cancer deaths. Screening more people can lead to more false positives, which may mean patients get biopsies and other interventions they don't need. And some cancers doctors find are so slow growing that they may never cause harm, said Dr Natalie Lui, a thoracic surgeon at the Stanford University School of Medicine. 'What if we're taking out all these tiny lung cancers that would not have been life-threatening?' Lui said. On the flip side, she thinks of the patients she regularly sees who have aggressive or advanced lung cancers but never smoked. 'If there was screening, we could save their life,' Lui said. The good news is that survival with advanced cancers has improved with newer therapies that effectively keep the disease at bay for years in many patients. Such treatments have benefited Leah Phillips, of Pewee Valley, Kentucky. Doctors first mistakenly diagnosed her with asthma and then anxiety. Later, they said she had pneumonia. When an oncologist finally told her in 2019 that she had metastatic lung cancer, he gave her six to 12 months to live. 'Go home and get your affairs in order,' Phillips remembered him saying. She was 43, and her children were 9, 13, and 14. 'I'm not leaving my kids,' Phillips thought. After getting a second opinion, she started taking a drug that targets one of the driver mutations in lung cancer. She prayed to make it to her eldest child's graduation. 'I cried through his entire senior year,' she said. In June, she watched her middle child graduate. 'Now I need to make it to the next one,' she said. Phillips, who co-founded a non-profit called the Young Lung Cancer Initiative to increase awareness of the condition, said people look at her askance when she tells them she has lung cancer but never smoked. They didn't know it was possible. It's not your grandfather's lung cancer anymore, she tells them. This article originally appeared in The New York Times.

Why Your Calf Cramps at Night–and How TCM, Diet, and Acupressure May Help

Waking up in the middle of the night with a searing calf cramp is a painful experience many are familiar with. However, what causes these spasms—and how can we prevent them? In an episode of the 'Health 1+1' program, Jonathan Liu, a professor of traditional Chinese medicine (TCM) at the Canadian College of Traditional Chinese Medicine and director of the Kang Mei TCM Clinic, discussed the causes of leg cramps, effective relief methods, and dietary choices that may help prevent their occurrence. Causes of Leg Cramps The following factors, Liu noted, may contribute to leg cramps: 1. Poor Blood Circulation Calf muscles, being far from the heart and affected by gravity, tend to have reduced blood flow. People who stand for prolonged periods, or those with vascular conditions—such as arteriosclerosis (hardening of the arteries), peripheral vascular disease (such as varicose veins), liver cirrhosis, or arthritis—may experience impaired circulation. This can disrupt calcium metabolism, triggering muscle cramps.
