China raises security concerns over Nvidia's H20 AI chips
China raised concerns over potential security risks associated with Nvidia's H20 artificial intelligence chip, casting uncertainty over the U.S. company's sales prospects in China, weeks after a U.S. export ban was reversed.
The Cyberspace Administration of China (CAC), the country's internet regulator, expressed concern about a U.S. proposal that advanced chips sold abroad be equipped with tracking and positioning functions.It stated that it had summoned Nvidia to a meeting on Thursday to discuss whether its H20 AI chip posed any backdoor security risks, as it was concerned that Chinese user data and privacy rights could be compromised.
Nvidia did not immediately respond to a Reuters' request for comment.
In May, U.S. Senator Tom Cotton introduced a bill that would direct the Commerce Department to require location verification mechanisms for AI chips subject to export restrictions, to curb Chinese access to advanced U.S. semiconductor technology.
Nvidia has been in the crosshairs of U.S.-China relations, and China's move comes shortly after the U.S. reversed an April ban on Nvidia selling the H20 chip to China this month. The company developed the H20 chip for the Chinese market after the U.S. imposed export restrictions on advanced AI chips in late 2023.
'Nvidia chips are now dispensable for China. They can be easily put on the negotiating table,' said Tilly Zhang, an analyst with Gavekal
Dragonomics.
'China obviously has more courage and domestic substitution capabilities compared to previous years to not rely on overseas technology.' This month, Nvidia CEO Jensen Huang embarked on a very public and effusive visit to China, where he sought to demonstrate his commitment to the Chinese market, met with government officials and praised the country's AI advances.
The CAC statement did not elaborate on potential backdoor security risks or indicate what the Chinese government was considering as a result.
Charlie Chai, an analyst with tech- and consumer-focused 86Research, said Beijing's warning was most likely a symbolic stance against similar objections made by U.S. authorities.
'However, we do not believe Beijing will make excessively harsh demands or introduce regulatory hurdles that will effectively drive Nvidia out of China – for the lack of alternatives, China still needs Nvidia chips for domestic research and applications,' Chai said.
Nvidia's products are highly sought after not just by Chinese tech companies but also by Chinese military bodies, state-run AI research institutes and universities. The company last week placed an order with contract manufacturer TSMC for 300,000 H20 chipsets due to strong demand, Reuters
reported.
Chinese authorities and industry associations have in the past accused U.S. tech companies of posing security risks, with varying consequences.
In early 2023, China barred key operators of the country's infrastructure from purchasing from Micron, saying that a review it conducted had found the U.S. memory chipmaker's products posed serious security risks.
Last year, the Cybersecurity Association of China, an industry group, called for Intel products sold in China to be subject to a security review, but Chinese regulators have not publicly responded.
Nvidia is also facing an antitrust investigation in China. The State Administration for Market Regulation announced late last year that it was investigating the chipmaker over suspected violations of the country's anti-monopoly law.
The regulator said Nvidia was also suspected of violating commitments it made during its acquisition of Israeli chip designer Mellanox Technologies, under terms outlined in the regulator's 2020 conditional approval of that deal.

US charges Chinese nationals with illegally shipping Nvidia chips to China
Authorities in the United States have charged two Chinese citizens with shipping tens of millions of dollars worth of advanced Nvidia chips to China in breach of export controls. Chuan Geng and Shiwei Yang are alleged to have 'knowingly and willfully' exported the graphic processing units (GPUs) used to power artificial intelligence without authorisation from October 2022 to July 2025, the US Department of Justice said on Tuesday. Export records indicate that Geng and Yang, both 28, organised at least 21 shipments though their El Monte, California-based company ALX Solutions Inc to companies in Singapore and Malaysia, the justice department said. The exports included a December 2024 shipment of Nvidia H100 GPUs – described as the most powerful chip on the market – that was 'falsely labelled' and had not obtained the necessary licence from the US Commerce Department, the justice department said. According to prosecutors, ALX Solutions received payments from firms in Hong Kong and China, including a $1m sum from a China-based company in January 2024, rather than the companies that accepted the shipments. Prosecutors alleged that a search of ALX Solutions' office and Geng and Yang's phone last week had revealed 'incriminating communications', including communications about shipping chips to China through Malaysia to evade US export reestrictions. Geng and Yang face a maximum penalty of 20 years in prison if convicted under the Export Control Reform Act. Al Jazeera could not immediately locate the accused's lawyers for comment. Santa Clara, California-based Nvidia said the case showed that 'smuggling is a nonstarter.' 'We primarily sell our products to well-known partners, including OEMs, who help us ensure that all sales comply with US export control rules,' a company spokesperson said. 'Even relatively small exporters and shipments are subject to thorough review and scrutiny, and any diverted products would have no service, support, or updates.' The US government has banned the export on the most advanced chips to China amid a heated battle for technological supremacy between Washington and Beijing. US officials have claimed that restrictions, many of which were introduced under former US President Joe Biden, are needed to safeguard national security. China, which has hit back with its own export controls against the US, has accused Washington of undermining global trade and abusing its dominance in tech. Last month, Nvidia CEO Jensen Huang announced that Washington had agreed to reverse its ban on the sale of its H20 GPU to China following discussions with US President Donald Trump. Huang said the lifting of the export ban on the H20, which was specifically designed for the Chinese market and is less powerful than the H100, would encourage 'nations worldwide to choose America.'

From nose to tail, how China is reshaping the aviation supply chain
Agencies While its home-grown airliners bring China the most attention in the complex, lucrative field of aviation, the country is also making strides in an equally important realm: the many components necessary to ensure the safe, smooth operation of jets and other aircraft. Recent developments in a number of areas show Beijing is continuing to reduce its reliance on foreign parts, close long-standing technological gaps and assert itself as a major player in civil aviation at all levels of the supply chain. We have gathered some of them below. During an interview on state broadcaster CCTV, Zhang Yanzhong of the Chinese Academy of Engineering offered a rare public update on one of the country's most closely watched aviation projects: the CJ-1000A, a domestically produced large commercial jet engine. Designed to power the Commercial Aircraft Corporation of China (Comac) C919 – China's answer to the Boeing 737 and Airbus A320 narrowbody aircraft – the CJ-1000A is seen as paramount to the country's efforts to limit its reliance on foreign aerospace technology. Zhang said the engine's development is progressing smoothly and remains on schedule. 'All I can say is that our engine is progressing as planned, and the current progress is very positive. As for when it will be installed on Chinese aircraft – just wait for the good news,' he told CCTV. The Aero Engine Corporation of China (AECC), the CJ-1000A's developer, has said their product will perform on par with CFM International's LEAP-1C engine, currently installed in C919 models flying commercial routes. A successful roll-out of the Chinese company's engine would represent a major leap forward in the country's campaign for aviation self-sufficiency. In July, Beijing's chief aviation regulator, the Civil Aviation Administration of China (CAAC), approved the manufacture of SINOPEC AEH I – a domestically developed aviation-grade fire-resistant hydraulic fluid. Manufactured by the China Petroleum and Chemical Corporation (Sinopec), it is the first home-grown product of its kind to receive official airworthiness approval. The certification paves the way for its use in civil aviation, and makes China the third country in the world capable of producing this specialised class of phosphate ester-based hydraulic fluid, critical for aircraft safety and performance. On June 5, China's AES100 turboshaft engine received a production licence in Hunan province and signed its first commercial sales contract. The AES100, also produced by AECC, is a 1,000-kilowatt-class advanced turboshaft engine tailored for civil aviation. Its manufacturer has touted its high safety standards, strong fuel efficiency, ease of maintenance and adaptability across various environments. It is designed to power twin-engined and single-engine helicopters as well as tilt-rotor aircraft, typically used for transport, sightseeing, emergency rescue and utility operations. As with the CJ-1000A, mass adoption of the engine would be a major step forward in China's efforts to source its aircraft propulsion systems locally after decades of relying on foreign suppliers. On average, lightning strikes a commercial airliner once a year. While rarely catastrophic, these incidents can pose serious risks, especially as traditional lightning protection systems struggle to keep up with the demands of high-speed, high-altitude flight. At a July 29 showcase at the National Communication Centre for Science and Technology in Beijing, Hefei Aerospace Electro-Physical Technology unveiled a new protection system to guard against this risk. Pan Yuan, also of the Chinese Academy of Engineering, said the event that lightning protection is critical for guaranteeing flight safety in complex weather. The technical challenge, he noted, lies not only in shielding the aircraft from direct lightning strikes but also in mitigating secondary effects, such as electrical surges that can damage on-board systems. Particularly complex is the protection of fuel systems, where failure could lead to disaster. The new system, if proven effective in commercial application, would grant Chinese-made aircraft a stronger reputation for safety and improve their case for overseas certification, an essential step for the country's jets to enter the global market.

China's Baidu to deploy robotaxis on rideshare app Lyft
Agencies Chinese internet giant Baidu plans to launch its robotaxis on rideshare app Lyft in Germany and Britain in 2026, pending regulatory approval, the two companies said on Monday. Last month, Baidu announced a similar agreement with Uber in Asia and the Middle East as it seeks to take pole position in the competitive autonomous driving field both at home and abroad. Lyft and Baidu said Monday that 'in the following years' the fleet of Apollo Go driverless cars will be expanded to thousands of vehicles across did not specify which other countries the cars would be deployed in, and it was not clear how long it might take to gain regulatory approval for the initial deployment. Driverless taxis are already on some roads with limited capacity in the United States and China, most notably in the central city of Wuhan, where a fleet of over 500 can be hailed by app in designated areas. Their reach is spreading, with Shanghai's financial district Pudong recently announcing a batch of permits for multiple companies to operate robotaxis. China's tech companies and automakers have poured billions of dollars into self-driving technology in recent years, with intelligent driving the new battleground in the country's cutthroat domestic car is not alone among Chinese companies in searching to expand its foothold abroad. Its rival WeRide is also active in the Gulf region, and in January announced it had been picked to lead a small pilot project in Switzerland. another Chinese company, said in May that it had signed a deal to launch its self-driving taxis on Uber in 'a key market in the Middle East later this year'. San Francisco-based Lyft in April said it had agreed to buy German taxi app Freenow, planting a flag in the European market. The acquisition marked Lyft's 'most significant expansion outside North America', the group said.
