China cautions tech firms over Nvidia H20 AI chip purchases, sources say
The Cyberspace Administration of China (CAC) and other agencies also held meetings with Baidu (0700.HK), opens new tab and smaller Chinese tech firms in recent weeks, said one of the two people and a third source.
The Chinese officials asked companies why they needed to buy Nvidia chips when they could purchase from domestic suppliers, the sources.
Authorities also expressed concerns that materials Nvidia has asked companies to submit for U.S. government review could contain sensitive information including client data, one of the sources said.
However, the people, who declined to be identified because the meetings were not public, said the companies have not been ordered to stop buying H20 chips.
Nvidia said on Tuesday the H20 chip was "not a military product or for government infrastructure".
"China has ample supply of domestic chips to meet its needs. It won't and never has relied on American chips for government operations, just like the U.S. government would not rely on chips from China," the statement said.
Baidu, ByteDance, Tencent and the CAC did not immediately respond to requests for comment.
Earlier on Tuesday, Bloomberg News reported that Chinese authorities have urged domestic companies to avoid using Nvidia's H20 chips, particularly for government-related purposes.
Several companies were issued official notices discouraging the use of the H20, a less-advanced chip, mainly for any government or national security-related work by state enterprises or private companies, the report said, citing people familiar with the matter.
In a separate report, The Information reported that ByteDance, Alibaba and Tencent had been ordered by the CAC in the past two weeks to suspend Nvidia chip purchases altogether, citing data security concerns.
The CAC directive was communicated at a meeting the regulator held with over a dozen Chinese tech firms, shortly after the Trump administration reversed the export curbs on H20 chips, according to the Information report.
Reuters could not immediately confirm the reports and Alibaba did not respond to a request for comment. Top contract chipmaker SMIC (0981.HK), opens new tab rose 5% on Tuesday on expectations of rising demand for locally-produced chips.
But even without an outright ban, the concerns expressed by Chinese authorities could threaten Nvidia's recently restored access to the Chinese market as Chinese companies look to keep in step with regulators.
Nvidia designed the H20 specifically for China after U.S. export restrictions on its more advanced AI chips took effect in late 2023. The H20 had since been the most sophisticated AI chip Nvidia was allowed to sell in China.
Earlier this year, U.S. authorities effectively banned its sale to China, but reversed the decision in July following an agreement between Nvidia and the Trump administration.
Last month, China's cyberspace regulator summoned Nvidia representatives, asking the company to explain whether the H20 posed backdoor security risks that could affect Chinese user data and privacy.
State-controlled media have intensified criticism of Nvidia in recent days. Yuyuan Tantian, affiliated with state broadcaster CCTV, published an article on WeChat over the weekend claiming H20 chips pose security risks and lack technological advancement and environmental friendliness.
The scrutiny threatens a significant revenue stream for Nvidia, which generated $17 billion from China sales in its fiscal year ended January 26 - or 13% of total revenue.
China has accelerated work on domestic AI chip alternatives, with companies, such as Huawei (HWT.UL) developing processors that rival the H20's performance, and Beijing urging the technology sector to become more self-sufficient.
However, U.S. sanctions on advanced chipmaking equipment, including lithography machines essential for chip production, have constrained domestic manufacturers' ability to boost production.
On Monday, U.S. President Donald Trump suggested that he might allow Nvidia to sell a scaled-down version of its advanced Blackwell chip in China, despite deep-seated fears in Washington that Beijing could harness U.S. AI capabilities to supercharge its military.
China's foreign ministry said on Tuesday it hoped the U.S. would act to maintain the stability and smooth operation of the global chip supply chain.
The Trump administration last week confirmed an unprecedented deal with Nvidia and AMD (AMD.O), opens new tab, which agreed to give the U.S. government 15% of revenue from sales of some advanced chips in China.
China's renewed guidance on avoiding chips also affects AI accelerators from AMD, Bloomberg also reported. It was not clear, however, whether any notices from Chinese authorities specifically mentioned AMD's MI308 chip.
AMD did not respond to a request for comment outside regular business hours.

CoreWeave revenue beats estimates on AI boom but shares fall on bigger loss
Aug 12 (Reuters) - CoreWeave (CRWV.O), opens new tab easily topped quarterly revenue estimates on Tuesday as the rapid adoption of artificial intelligence tools boosted demand for its cloud services, but a bigger-than-expected net loss sent its shares slumping 10% after the bell. The company currently operates 33 AI data centers across the U.S. and Europe and offers access to backer Nvidia's (NVDA.O), opens new tab chips, which are highly coveted by enterprises to train and run large AI models amid intense competition. CoreWeave reported revenue backlog of $30.1 billion as of end of June, compared with $25.9 billion on March 31. "Demand is humming, but it is the cost of growth that tempered the stock down in aftermarket trading," said Michael Ashley Schulman of Running Point Capital Advisors. Operating expenses jumped to $1.19 billion in the second quarter, from $317.7 million a year earlier. The company posted a net loss of $290.5 million, compared with analysts' average estimate of $190.6 million, according to data compiled by LSEG. "We are scaling rapidly as we look to meet the unprecedented demand for AI," CEO Michael Intrator said in the earnings statement. Investors have also focused on the company's reliance on a few big customers. "The backlog surge to $30B+ suggests demand visibility well beyond 2025, but the concentration in mega-customers like OpenAI means those relationships remain both the crown jewel and the single point of failure," said eMarketer analyst Jeremy Goldman. Meanwhile, CoreWeave executives reiterated the benefits of its $9 billion all-stock deal for crypto miner Core Scientific (CORZ.O), opens new tab. The deal, announced in July, is facing opposition. Core Scientific's largest shareholder, Two Seas Capital, has said it would vote against the sale. CoreWeave reported second-quarter revenue of $1.21 billion, beating estimates of $1.08 billion. The Livingston, New Jersey-based company raised its annual revenue forecast to be between $5.15 billion and $5.35 billion. It had previously projected annual revenue of $4.9 billion to $5.1 billion. Shares of the company, which reaffirmed its annual capital expenditure projection, were trading at $133.71. They have gained nearly three-fold since the IPO in March.

Japan manufacturers' sentiment rises in August after US trade deal, but tariffs cloud outlook: Reuters Tankan poll
TOKYO, Aug 13 (Reuters) - Japanese manufacturers grew more confident about business conditions in August after a trade agreement between Tokyo and Washington, but remained cautious about the outlook due to potential U.S. tariff impacts, a Reuters Tankan poll showed. The monthly poll, which tracks the Bank of Japan's quarterly tankan business survey, showed the manufacturers' sentiment index rising to plus 9 in August from plus 7 in July, marking a second straight month of improvement. But the index is projected to decline to plus 4 over the next three months, signalling that manufacturers remain guarded about how the U.S. tariffs would impact their businesses. The poll, conducted between July 30 and August 8, surveyed 497 major non-financial companies, with 241 responding on condition of anonymity. Last month, Japan secured a trade deal with the U.S. that lowers tariffs on cars and other goods to 15% in exchange for a U.S.-bound $550 billion Japanese investment package that will come in the form of equity, loans and guarantees. Among manufacturers, the sentiment index for the transport machinery sector, which includes Japan's vital auto industry, surged to plus 25 in August from plus 9 in July. However, it is projected to slip back to plus 9 in November. "The business outlook remains uncertain as the U.S. tariff policies are forcing the entire automobile industry to overhaul its production plans," an auto industry manager wrote in the survey. Another manager from the sector cited slowing sales of Japanese cars in China, in addition to the U.S. tariffs, as a source of concern. The food industry saw the sharpest decline among all sectors, with its sentiment index falling to minus 25 from zero, with some managers pointing to persistent surges in ingredient and material costs. For non-manufacturers, the business sentiment index fell to plus 24 in August from plus 30 in July, its first decline in five months. Companies expect a slight rebound to plus 25 in the next three months. Real estate and construction firms, as well as retail firms, reported declines in their respective indexes, though they remained in positive territory, signalling that optimists outnumber pessimists. Some managers at retail firms cited a drop in store visitors, while a services firm manager said heatwaves were affecting business.

China's fight against price wars is an uphill battle
HONG KONG, August 13 (Reuters) - Overcapacity has made its way into China's domestic market, with price wars leading to collapsing profitability and accelerating deflation. The government has responded by launching a so-called 'anti-involution' program to combat deflationary price wars. It's had some early wins, but this could be a lengthy battle. The Chinese internet slang for 'involution' originally referred to competitive pressures faced by young Chinese in education and the workplace. Since early 2024, however, the word has come to describe supposedly excessive, unsustainable competition among Chinese firms, where more resources are being invested without increasing higher returns. The Chinese government began to highlight the economic dangers of involution as early as June 2024, opens new tab in the face of declining corporate margins and profitability across diverse sectors such as electric vehicles, solar panels, lithium batteries, steel, cement and food delivery. Critiques of "excessive" competition grew much louder in the first half of 2025 as several price wars escalated. In particular, EV leader BYD( opens new tab started sharply cutting prices, and food delivery giant Meituan ( opens new tab and new ecommerce platform opens new tab began offering discounts and subsidies. Increased competition in China also appears to be amplifying deflationary pressures. While China's Producer Price Index (PPI) has been in negative territory for much of the last three years, hopes of escaping this morass were ignited in mid-2024 as domestic demand appeared to be recovering. However, that optimism was doused this year as price wars intensified, with PPI falling by 3.6% year-on-year in the most recent report. China's government, recognising that industrial overcapacity is a potential danger to the domestic economy, launched a multi-pronged anti-involution campaign in July. The program seeks to channel investment funds to advanced manufacturing, control production in highly competitive industries like steel, oversee pricing and subsidies in EVs and food delivery, and continue phasing out obsolete industrial capacity. It's early days, but some nascent impacts are visible. Carmakers' average price discount declined in July, and Meituan, and Alibaba ( opens new tab recently agreed to end aggressive discounting in food delivery and promote "fair competition". Industry consolidation has accelerated as well. Polysilicon manufacturers are discussing the creation of a $7 billion fund to acquire and shut down almost one-third of their production capacity and restructure part of the loss-making sector. Additionally, the country's largest coal miner, China Shenhua Energy ( opens new tab , stated its intention to acquire various assets from the subsidiaries of its controlling shareholder to improve operational efficiency. China's anti-involution program faces myriad hurdles, however. For one, most of the targets of the anti-involution program are in the private sector, which means they will be making voluntary pledges to maintain pricing discipline and thus could revert to aggressive tactics in the face of market pressure. Importantly, Beijing's previous supply-side structural reforms from 2015-17 reduced excess capacity among state-owned firms, over which Beijing, by definition, had much more control. Moreover, many of China's local governments are highly indebted and may prioritise short-term revenue generation over long-term reform, potentially offering subsidies to firms to attract investment even in industries targeted by the anti-involution campaign. Innovation in emerging technologies could also be a casualty if deterring overlapping investments hinders experimentation with different approaches. And tighter oversight on pricing and capacity could dampen private capital's investment enthusiasm overall. Finally, one of the biggest risks to the implementation of the program is the possibility of job losses as industries consolidate and become more inefficient. While China's youth unemployment rate has declined recently, it remains high and could increase over the next few months as over 12 million new university graduates join the workforce. And the private sector – the target of the anti-involution program – generates the vast majority of China's incremental employment. China's anti-involution efforts have had some success, but this will likely not be a short fight. First, to truly absorb excess capacity in various industries, Beijing will almost certainly have to stimulate domestic consumption more aggressively than it has in the past. Sentiment among Chinese consumers remains quite low, implying that the monetary and fiscal stimuli undertaken by China's government over the past year have had only a limited impact. The government could also consider more innovative, hitherto untested policies. For example, it could mandate superior product quality to weed out players who compete purely on cost to encourage industry consolidation. However, defining 'low quality' and enforcing standards would be challenging, and this strategy may be less effective in services industries. Another way to reduce the incentives for extreme competition would be encouraging collaboration between firms through technology sharing and mutual equity holdings. And the increased availability of patient long-term capital could obviate the need for companies to ramp up production and revenues rapidly. The anti-involution program marks a new phase of China's pursuit of high-quality development. Enforcing pricing discipline and market stability in furiously competitive industries will be no easy task. That means an updated playbook may be needed.
