Nvidia's H20 chips under fire in China: What's behind the dispute?
Citing a source, Reuters said that authorities were worried that the materials Nvidia asks its buyers to submit to the US government could contain sensitive information, including client data.
Beijing 'discourages' Nvidia H20 chip use
The report further said that although the companies have not been ordered to stop buying the Nvidia H20 chips, but Chinese officials have discouraged its use, especially in government-related or national security projects.
Earlier on Tuesday, several companies received official notices urging them to avoid the H20 chips for state enterprise or private sector work tied to national security, according to a report by Bloomberg.
Another report claimed that ByteDance, Alibaba and Tencent were told by the CAC in the past two weeks to suspend H20 purchases altogether due to data security concerns, The Information reported on Tuesday. The report said the directive came shortly after the US reversed export curbs on the chip. Meanwhile, Nvidia on Tuesday clarified that the H20 chip was 'not a military product or for government infrastructure'.
What's behind China-Nvidia fallout?
Tensions between Nvidia and Chinese authorities have grown over the past two years amid tighter US export controls on advanced chips.
The US restricted the sale of Nvidia's most powerful AI chips to China under the Biden administration in 2022, in an effort to slow Beijing's progress in artificial intelligence and military technologies. In response, Nvidia developed the H20, a less advanced processor designed to comply with US rules while serving the Chinese market. But in April this year, the Trump administration further imposed a new ban specifically on Nvidia's H20 chips, which had been designed for the Chinese market after previous rounds of export controls.
Since the export ban, the H20 became the most sophisticated chip Nvidia could sell in China after the 2022 curbs. The Trump administration reversed the decision in July under a deal that requires Nvidia and AMD to share 15 per cent of revenue from certain China sales with the US government.
But beginning this month, Chinese regulators have been urging companies, particularly state-owned enterprises and firms involved in sensitive projects, to avoid using the H20 citing potential 'backdoor' security risks, the chip's technological limitations, and the need to prioritise domestic alternatives such as those made by Huawei.
Chinese state media have also increased coverage of alleged security vulnerabilities and shortcomings of Nvidia chips, reflecting Beijing's broader push for self-reliance in technology.
Impact on Nvidia's China business
The scrutiny threatens Nvidia's $17 billion in annual sales to China, which accounts for 13 per cent of its total revenue.
The uncertain trade policies of the US and its back-and-forth attitude towards China has seen the communist nation pushing for accelerating work on local AI processors, even though US restrictions on advanced chip-making equipment, including lithography machines, have limited production capacity. Huawei and other domestic firms have been developing chips that rival the H20's performance.
China's Ministry of Foreign Affairs stated on Tuesday that it hoped the US would help maintain stability in the global chip supply chain.

Top 10 AI companies in the world: See who's winning the race between Sam Altman, Elon Musk and other tech giants
Top 10 AI companies in the world Forbes: Artificial intelligence isn't slowing down, it is only growing bigger, bolder, and more embedded in the way modern businesses operate. More than two years after ChatGPT took the world by storm, AI remains a top priority for venture capitalists and tech leaders. But the conversation has shifted: instead of only racing to build the most powerful AI models, many startups are focusing on real-world applications—tools that save time, cut repetitive work, and make tasks easier across sectors like engineering, healthcare, legal services, and sales. This shift is reflected in Forbes' seventh annual AI 50 list, created in partnership with Sequoia and Meritech Capital, which spotlights the most promising privately-owned AI companies worldwide—from established giants to rising newcomers.. Newcomers to the list include Anysphere—better known as Cursor—a three-year-old AI coding assistant valued at $2.5 billion and generating over $100 million in annual revenue. Speak, an AI-powered language tutoring app worth $1 billion, serves around 10 million learners of English and Spanish. Massachusetts-based OpenEvidence, another unicorn, offers an AI-driven medical search tool that distils complex information into concise summaries for doctors. While rising startups are making waves, AI model-building heavyweights still dominate the top tier. OpenAI and Anthropic—two of the sector's most well-funded players—have raised a combined $81 billion, more than half of the total $142.45 billion secured by this year's AI 50 companies. But the race is intensifying: Elon Musk's xAI has raised $12.1 billion; former OpenAI CTO Mira Murati is launching Thinking Machine Labs, aiming for $1 billion at a $9 billion valuation; and AI pioneer Fei-Fei Li, dubbed the 'godmother of AI,' has entered the fray with World Labs, backed by $291.5 million to build systems that interpret physical spaces. On the enterprise side, Writer has secured $326 million to develop proprietary AI models for corporate tasks like drafting marketing blogs or combing through large document archives. Powering all of these AI dreams are the often-overlooked infrastructure providers. AI companies need huge amounts of computing power, expensive chips, and energy-intensive data centers to train and run their systems. That demand has boosted companies like Crusoe ($2.8 billion valuation), Lambda ($2.5 billion), and Together AI ($3.3 billion), all working to supply the raw computing power AI development requires. Some startups are proving that AI model training doesn't have to burn through endless amounts of money. Chinese company DeepSeek is an example, it's shown that building powerful models can be done more cost-efficiently. While it isn't on the AI 50 list this year due to unclear details about its funding, revenue, and operations, DeepSeek represents a growing group of Chinese AI companies that are becoming serious contenders in the global AI race. From billion-dollar app startups to massive model-makers and the infrastructure that powers them, AI's ecosystem has never been more varied, or more competitive. And if this year's AI 50 list is anything to go by, the race is shifting from who can build the biggest model to who can build the most useful AI for real-world needs. Source: Forbes

Ahead Of Trump-Putin Talks, Key US Official's Big Warning On India Tariffs
US Treasury Secretary Scott Bessent has warned India of increasing secondary tariffs over the Russian oil trade. He said that the raise in tariffs is dependent on the outcome of US President Donald Trump's high-stakes meeting with Russian President Vladimir Putin in Alaska on Friday. In an interview to Bloomberg TV on Wednesday, Bessent said, "We've put secondary tariffs on Indians for buying Russian oil. And I could see, if things don't go well, then sanctions or secondary tariffs could go up." Earlier this month, Trump had slapped India with 50 per cent tariffs, including 25 per cent as penalty for buying Russian oil and weapons. Responding to the tariffs, the Ministry of External Affairs has said that the targeting of India is unjustified and unreasonable. "Like any major economy, India will take all necessary measures to safeguard its national interests and economic security," it said. Statement by Official Spokesperson⬇️ 🔗 — Randhir Jaiswal (@MEAIndia) August 6, 2025 "President Trump is meeting with President Putin, and the Europeans are in the wings carping about how he should do it, what he should do. The Europeans need to join us in these sanctions. The Europeans need to be willing to put on these secondary sanctions," Bessent said. Along with this, Trump has also warned Russia of "severe consequences" if Moscow does not agree to a peace deal. About 35-40 per cent of India's oil imports come from Russia, a steep increase from 3 per cent in 2021. New Delhi's purchase of discounted Russian oil since the beginning of the Ukraine war has led to a strain in its ties with Washington. Although India is not the only country purchasing Russian oil, it is the only country to have suffered from Trump's effort to get a ceasefire in Ukraine. This is a second remark Bessent has made about India after he called India a "bit recalcitrant" regarding the trade deal, in an interview with Fox Business. Congress MP Shashi Tharoor on Thursday hit back at Bessent through a post on X. He said, "I hear some people are accusing India of being 'recalcitrant'. I say, far better to be recalcitrant, than to be tractable, submissive or acquiescent in injustice." I hear some people are accusing India of being 'recalcitrant'. I say, far better to be recalcitrant, than to be tractable, submissive or acquiescent to injustice. — Shashi Tharoor (@ShashiTharoor) August 14, 2025 Trump's tariffs on India are set to come into effect on 27th August.
