Nvidia summoned by Chinese authorities over ‘serious security issues' in AI chips
Nvidia is a world-leading producer of AI semiconductors, but the United States effectively restricts which chips it can export to China on national security grounds.
A key issue has been Chinese access to the "H20", a less powerful version of Nvidia's AI processing units that the company developed specifically for export to China.
The California-based firm said earlier this month that it would resume H20 sales to China after Washington pledged to remove licensing curbs that had halted exports.
But the firm still faces obstacles -- US lawmakers have proposed plans to require Nvidia and other manufacturers of advanced AI chips to include built-in location tracking capabilities.
And on Thursday, Beijing's top internet regulator said it had summoned Nvidia representatives to discuss recently discovered "serious security issues" involving the H20.
The Cyberspace Administration of China said it had asked Nvidia to "explain the security risks of vulnerabilities and backdoors in its H20 chips sold to China and submit relevant supporting materials".
The statement posted on social media noted that, according to US experts, location tracking and remote shutdown technologies for Nvidia chips "are already matured".
The announcement marked the latest complication for Nvidia in selling its advanced products in the key Chinese market, where it is in increasingly fierce competition with homegrown technology firms.
CEO Jensen Huang said during a closely watched visit to Beijing this month that his firm remained committed to serving local customers.
Huang said he had been assured during talks with top Chinese officials during the trip that the country was "open and stable".
"They want to know that Nvidia continues to invest here, that we are still doing our best to serve the market here," he said.
Nvidia this month became the first company to hit $4 trillion in market value -- a new milestone in Wall Street's bet that AI will transform the global economy.
New hurdles to the firm's operation in China come as the country's economy wavers, beset by a years-long property sector crisis and heightened trade headwinds under US President Donald Trump.
Chinese President Xi Jinping has called for the country to enhance self-reliance in certain areas deemed vital for national security -- including AI and semiconductors -- as tensions with Washington mount.
The country's firms have made great strides in recent years, with Huang praising their "super-fast" innovation during his visit to Beijing this month.

Did US use Microsoft bugs to spy on China's military?
Synopsis China accuses the US of exploiting Microsoft's email server vulnerabilities to steal military data and launch cyberattacks on its defense sector. This accusation follows Microsoft's repeated blaming of China for major cyber incidents involving its software, including breaches of Exchange servers and SharePoint. The US embassy has not yet responded to the allegations. Reuters Microsoft logo is seen through broken glass in this illustration taken, January 25, 2023. China accused the US of exploiting a flaw in Microsoft Corp.'s email servers to steal military data and carry out cyberattacks on its defense sector, Bloomberg Cyber Security Association of China, a little-known entity backed by the Cyberspace Administration of China, said Friday that US actors had been linked to two major cyberattacks on Chinese military companies. The attackers allegedly exploited vulnerabilities in Microsoft Exchange to control the servers of a key defense-sector company for nearly a year, it Microsoft has repeatedly blamed China for major cyber incidents tied to its software. In 2021, an alleged Chinese campaign compromised tens of thousands of Microsoft Exchange servers. In 2023, another alleged Chinese breach of Exchange impacted senior US officials' email accounts, prompting a US government review that accused Microsoft of a 'cascade of security failures.' Last month, Microsoft also said state-backed Chinese hacking groups exploited flaws in its SharePoint file-sharing software.'Every nation state in the world carries out offensive cybersecurity campaigns against others,' said Jon Clay, vice president of threat intelligence at Trend Micro. 'I'm assuming at this point, because of the recent SharePoint vulnerability that Microsoft attributed to China, they are coming out and saying, hey, the US has been targeting us with exploits.'The US embassy in Beijing did not immediately respond to Bloomberg's request for comment. Ben Read, director of strategic threat intelligence at noted in a recent blog that China increasingly uses 'public attribution of cyber activities' to pressure Taiwan and shape 'the international dialogue around cybersecurity.' Earlier this year, Beijing accused Taiwan of multiple April, China alleged that three NSA employees hacked the Asian Winter Games in Harbin, targeting systems containing personal information of event participants. While Washington has often named alleged Chinese hackers and filed charges against them, Beijing has historically avoided directly accusing US spies, Bloomberg said.

China's solar giants quietly shed a third of their workforces last year
Synopsis China's solar industry, facing overcapacity and price wars, witnessed significant job losses as major firms shed nearly one-third of their workforce last year. This downturn, exacerbated by U.S. tariffs and tepid demand, has prompted Beijing to consider intervention, including potential production cuts and price controls. Reuters Workers carry solar panels to install them at a solar farm in the desert, in Lingwu, Ningxia Hui Autonomous Region, China April 14, 2025. The job cuts illustrate the pain from the vicious price wars being fought across Chinese industries, including solar and electric vehicles, as they grapple with overcapacity and tepid demand. BEIJING: China's biggest solar firms shed nearly one-third of their workforces last year, company filings show, as one of the industries hand-picked by Beijing to drive economic growth grapples with falling prices and steep job cuts illustrate the pain from the vicious price wars being fought across Chinese industries, including solar and electric vehicles, as they grapple with overcapacity and tepid demand. The world produces twice as many solar panels each year as it uses, with most of them manufactured in China. Longi Green Energy, Trina Solar, Jinko Solar, JA Solar, and Tongwei , collectively shed some 87,000 staff, or 31% of their workforces on average last year, according to a Reuters review of employment figures in public say the previously unreported job losses were likely a mix of layoffs and attrition due to cuts to pay and hours as companies sought to stem losses. Layoffs are politically sensitive in China, where Beijing views employment as key to social stability. Other than a 5% cut acknowledged by Longi last year, none of the firms mentioned above have announced any job cuts or responded to questions from Reuters."The industry has been facing a downturn since the end of 2023," said Cheng Wang, an analyst at Morningstar. "In 2024, it actually got worse. In 2025, it looks like it's getting even worse." Since 2024, more than 40 solar firms have delisted, gone bankrupt or been acquired, according to a presentation by the photovoltaic industry association in July. China's solar manufacturers built new factories at a fever pitch between 2020 and 2023 as the state redirected resources from the sinking property sector to what it used to call the "new three" growth industries: solar panels, electric cars and building spree led to falling prices and a brutal price war made worse by U.S. tariffs thrown up against exports from the many Chinese-owned factories in Southeast Asia. The industry lost $60 billion last to comeWhile analysts say it is unclear whether job cuts continued this year, Beijing is increasingly signalling it intends to intervene to cut capacity, sending polysilicon prices soaring nearly 70% in July while solar panel prices have increased more polysilicon producer GCL told Reuters on Thursday that top producers plan to set up anOPEC-like entityto control prices and supply. The group is also setting up a 50-billion yuan vehicle to buy and shut around a third of the industry's lower-quality production capacity. President Xi Jinping in early July called for an end to "disorderly price competition," and three days later the industry ministry pledged to calm price wars and retire outdated production capacity during a meeting with solar industry Beijing has not said when or how it will act, a source with direct knowledge of the matter said it was determined to focus on the issue before the end of the current five-year plan this year. Officials in eastern China's Anhui province, a manufacturing hub, told solar company executives in June to stop adding new manufacturing and shut production lines operating at under 30% capacity, according to two industry sources who declined to be identified due to the sensitivity of the matter.A board member at a solar firm in the province said new capacity had already required verbal approval from powerful state planner the National Development and Reform Commission (NDRC) this year. They asked for their company's name to be withheld because the discussions were private. No easy fix But many provincial governments are likely to be reluctant to crack down hard on overcapacity, analysts say. These officials are scored on jobs and economic growth and are loathe to see local champions sacrificed to meet someone else's target. Trina Solar's chairman told an industry conference in June that new projects had begun this year despite the NDRC calling for a halt in foot-dragging reflects the scale of the cull required. Jefferies analyst Alan Lau estimated at least 20-30% of manufacturing capacity would have to be eliminated for companies to return to profitability."There's a lot of overcapacity in China, like steel, like cement, but you don't see any industry in the past having industry-wide cash loss for one and a half years already," Lau losses are on the same scale as in real estate, another crisis-hit sector, even though solar is only about one-tenth the size, he said. "This is highly unusual and highly abnormal."

Rebalancing trade ties: India's path to reduced Chinese import dependence
Synopsis Despite escalating geopolitical frictions and diplomatic tensions, India's merchandise trade with China has shown significant resilience, increasing by 81% to $128 billion in FY 2024-25 from $71 billion in FY2015-16. iStock India's top imports from China in 2024 were concentrated in machinery and electronics, such as electronic integrated circuits, telephone sets and parts, automatic data processing machines, and photovoltaic cells. Over the past decade, India's merchandise trade with China has shown significant resilience, increasing by 81% from $71 billion in FY 2015-16 to $128 billion in FY 2024-25 (Figure 1), despite escalating geopolitical frictions and diplomatic tensions. However, this growth masks a significant imbalance for India. Although total trade has grown, this expansion has been largely driven by an 84% surge in imports. In 2024-25, imports from China accounted for about 16% of India's total import basket, totalling around $114 billion. This made China India's largest source of imports. The economic asymmetry has been further aggravated by the relatively sluggish growth in India's exports to China, leading to a widening trade deficit over the years. In 2024-25, this deficit reached a record high of $99.2 billion. China now accounts for nearly 35% of India's overall trade deficit, making it the country's biggest trade imbalance with another country. India's top imports from China in 2024 were concentrated in machinery and electronics, such as electronic integrated circuits, telephone sets and parts, automatic data processing machines, and photovoltaic cells. These items together accounted for 56% of total imports from China (Figure 2). Significant import volumes were also concentrated in critical sectors, such as chemical products (15%), which include pharmaceuticals, organic and inorganic chemicals, and fertilisers. Base metals, plastics, and rubber followed at 8% and 6%, 75% of India's imports from China comprised high- and medium-technology manufactures in 2024 (Figure 3). In terms of the industrial use, intermediate and capital goods accounted for 55%.China's dominance is further underscored by its overwhelming share in India's global imports in several products. In 2024, India imported 560 different products from China, with at least 80% of its total global imports originating from China alone. The combined value of these imports was approximately $19.5 heavy dependence on Chinese imports raises critical concerns about India's industrial reliance and strategic autonomy. However, as highlighted in the Economic Survey 2023-24 and echoed by several prominent economists, a complete decoupling from Chinese supply chains may not be a viable option for India due to China's deep integration into global supply chains, particularly the large share of intermediate and capital goods sourced from China that are vital for sustaining India's manufacturing capacity. Hence, a more pragmatic approach would be to reduce overdependence on imports by encouraging greater Chinese foreign direct investment (FDI) in India's manufacturing sector, especially through the Production Linked Incentive (PLI) scheme. This approach holds particular promise for India's electronics and automobile sectors—areas where import dependence on China is high. Another key concern regarding the long-term sustainability of India's trade balance with China is the dominance of uncompetitive imports in India's import basket. A product imported from China can be considered uncompetitive when its per-unit import price is higher than that offered by at least one of India's top three alternative supplier countries for the same product. In 2024, of India's top 50 imported products from China at the HS-6-digit level, 23 were uncompetitive. For instance, penicillin, which India imports from China, is available from Hong Kong at a 15% lower price, and from the UAE, it is about 36% cheaper. These uncompetitive products alone made up nearly $30 billion in imports, which is about two-thirds (64%) of the total value of India's top 50 imports from China, dominated primarily by machinery and electronics, followed by chemical goods, which include pharmaceuticals as well (Figure 4).The persistence of such uncompetitive imports despite available cheaper alternatives can, in part, be attributed to China's strategic export promotion practices. These include offering deferred payment options, low-interest financing, and technical cooperation arrangements for its exporters to make its exports more attractive to importing countries. Thus, the China Export and Credit Insurance Corporation—Sinosure, the country's official export credit agency (ECA), provides credit insurance to Chinese companies engaged in international trade, safeguarding them against the risk of non-payment. This protection encourages exporters to offer deferred payment terms to foreign buyers, enhancing trade turnover and benefiting both parties. Hence, these mechanisms significantly reduce payment risk, encourage higher trade turnover, and make Chinese products reducing India's dependence on uncompetitive imports from China should remain a key strategic priority. This can be achieved by gradually diversifying towards more price-competitive suppliers and by seeking new source countries for imports. Simultaneously, India should make concerted efforts to encourage Chinese FDI into non-strategic sectors where the country faces high import dependence, as this could strengthen domestic manufacturing capacity along with paving the way for a more sustainable trade relationship with China.
