Nvidia’s CEO Jensen Huang says the technology giant has won approval from the Trump administration to sell its advanced H20 computer chips used to develop artificial intelligence to China.

The news came in a company blog post late Monday, which stated that the US government had "assured" Nvidia that licenses would be granted — and that the company "hopes to start deliveries soon." Shares of the California-based chipmaker were up over 4% by midday Tuesday.

Huang also spoke about the coup on China’s state-run CGTN television network, in remarks shown on X.

"Today, I'm announcing that the US government has approved for us filing licenses to start shipping H20s," Huang told reporters in Beijing.

He added that half of the world's AI researchers are in China. "It's so innovative and dynamic here in China that it's really important that American companies are able to compete and serve the market here," he said.

Huang recently met with President Donald Trump and other US policymakers and is in Beijing this week to attend a supply chain conference and speak with Chinese officials. The broadcast showed Huang meeting with Ren Hongbin, the head of the China Council for Promotion of International Trade, host of the China International Supply Chain Expo, which Huang was attending. Nvidia is an exhibitor.

Nvidia has profited enormously from the rapid adoption of AI, becoming the first company to have its market value surpass $4 trillion last week. However, the trade rivalry between the US and China has been weighing heavily on the industry.

Here's what we know.

What is Nvidia's H20 chip? The H20 graphics processing unit, or GPU, is an advanced AI chip — a type of device used to build and update a range of AI systems. But it's less powerful than Nvidia's top semiconductors today.

That's because the H20 chip was developed to specifically comply with US restrictions for exports of AI chips to China. Nvidia's most advanced chips, which carry more computing power, are off-limits to the Chinese market.

Washington has been tightening controls on exports of advanced technology to China for years, citing concerns that know-how meant for civilian use could be deployed for military purposes. And in January, before Trump began his second term in office, President Joe Biden's administration launched a new framework for exporting advanced computer chips used to develop AI in an attempt to balance national security concerns about the technology with the economic interests of producers and other countries.

Restrictions on sales of advanced chips to China have been central to the AI race between the world's two largest economic powers, but such controls are also controversial.

Proponents argue that these restrictions are necessary to slow China down enough to allow US companies to keep their lead. Meanwhile, opponents say the export controls have loopholes and could still spur innovation. The emergence of China’s DeepSeek AI chatbot in January particularly renewed concerns over how China might use advanced chips to help develop its own AI capabilities.

What's happened since Trump took office? In April, the White House announced that it would restrict sales of Nvidia’s H20 chips to China — as well as MI308 chips from rival chipmaker Advanced Micro Devices with the Trump administration again citing national security.

At the time, Nvidia said these tighter export controls would cost the company an extra $5.5 billion and Huang and other technology leaders have been lobbying Trump to reverse the restrictions since. They've argued that such limits hinder US competition in a sector in one of the world’s largest markets for technology, and have also warned that US export controls could end up pushing other countries toward China’s AI technology.

Monday's announcement from Nvidia signals that its lobbying efforts paid off. White House AI and crypto adviser David Sacks told Bloomberg on Tuesday that allowing Nvidia to restart Chinese sales of its H20 chip would help the US better compete abroad, particularly with Chinese chipmaker Huawei Technologies.

Meanwhile, Commerce Secretary Howard Lutnick told CNBC on Tuesday that the renewed sale of H20 chips in China was linked to a trade agreement made between the two countries on rare earth magnets and maintained that the administration was also reversing course from April's restrictions because the US still doesn't sell China "our best stuff."

Still, calls for restrictions on advanced chip exports to China have persisted among US lawmakers on both sides of the aisle.

Just last week, Sens. Elizabeth Warren and Jim Banks wrote a letter to Huang noting that the hardware powering advanced AI "is of immense strategic importance" and again warned that this kind of technology could be used to accelerate Beijing’s effort to modernize its military if exported freely. US lawmakers have also proposed that chips subject to export controls should be tracked, to ensure they don’t end up in the wrong places.

Beyond export controls, California-based Nvidia — like other tech giants today — has been caught in the crosshairs of Trump’s tariff wars abroad, particularly amid America's tit-for-tat levies with China. But Beijing and Washington recently agreed to pull back some non-tariff restrictions. China says it’s approving permits for rare earth magnets to be exported to the US, while Washington has lifted curbs on chip design software and jet engines.

Nvidia and its CEO have also garnered Trump’s favor in recent months. In April, the company announced that it would be producing its AI chips in the US for the first time, starting with more than one million square feet of manufacturing space to build and test its specialized Blackwell chips in Arizona and AI supercomputers in Texas.

Trump was quick to applaud Nvidia's move. He introduced Huang as a "smart cookie" who was helping bring jobs to the US at an "Investing in America" event held at the White House later that month.

Similar to Nvidia, AMD is now also poised to restart Chinese sales of its MI308 chips. The California-based company said in a statement that the Commerce Department was moving forward with license applications for these exports to China, and that it plans to resume shipments as those licenses are approved.

Researchers at the Paul Scherrer Institute PSI have achieved a breakthrough on the path to practical application of lithium metal all-solid-state batteries.

The team expects the next generation of batteries to store more energy, are safer to operate, and charge faster than conventional lithium-ion batteries.

The team has reported these results in the journal Advanced Science.

All-solid-state batteries are considered a promising solution for electromobility, mobile electronics, and stationary energy storage – in part because they do not require flammable liquid electrolytes and therefore are inherently safer than conventional lithium-ion batteries.

Two key problems, however, stand in the way of market readiness: On the one hand, the formation of lithium dendrites at the anode remains a critical point.

On the other hand, an electrochemical instability – at the interface between the lithium metal anode and the solid electrolyte – can impair the battery’s long-term performance and reliability.

To overcome these two obstacles, the team led by Mario El Kazzi, head of the Battery Materials and Diagnostics group at the Paul Scherrer Institute PSI, developed a new production process:

“We combined two approaches that, together, both densify the electrolyte and stabilize the interface with the lithium,” the scientist explained.

Central to the PSI study is the argyrodite type LPSCl, a sulphide-based solid electrolyte made of lithium, phosphorus, and sulphur. The mineral exhibits high lithium-ion conductivity, enabling rapid ion transport within the battery – a crucial prerequisite for high performance and efficient charging processes.

To densify argyrodite into a homogeneous electrolyte, El Kazzi and his team did incorporate the temperature factor, but in a more careful way: Instead of the classic sintering process, they chose a gentler approach in which the mineral was compressed under moderate pressure and at a moderate temperature of only about 80 degrees Celsius.

The result is a compact, dense microstructure resistant to the penetration of lithium dendrites. Already, in this form, the solid electrolyte is ideally suited for rapid lithium-ion transport.

To ensure reliable operation even at high current densities, such as those encountered during rapid charging and discharging, the all-solid-state cell required further modification.

For this purpose, a coating of lithium fluoride (LiF), only 65 nanometres thick, was evaporated under vacuum and applied uniformly to the lithium surface – serving as a ultra-thin passivation layer at the interface between the anode and the solid electrolyte.

In laboratory tests with button cells, the battery demonstrated extraordinary performance under demanding conditions.

“Its cycle stability at high voltage was remarkable,” said doctoral candidate Jinsong Zhang, lead author of the study.

After 1,500 charge and discharge cycles, the cell still retained approximately 75% of its original capacity.

This means that three-quarters of the lithium ions were still migrating from the cathode to the anode. “An outstanding result. These values are among the best reported to date.”

Zhang therefore sees a good chance that all-solid-state batteries could soon surpass conventional lithium-ion batteries with liquid electrolyte in terms of energy density and durability.

Thus El Kazzi and his team have demonstrated for the first time that the combination of solid electrolyte mild sintering and a thin passivation layer on lithium anode effectively suppresses both dendrite formation and interfacial instability.

This combined solution marks an important advance for all-solid-state battery research – not least because it offers ecological and economic advantages: Due to the low temperatures, the process saves energy and therefore costs.

“Our approach is a practical solution for the industrial production of argyrodite-based all-solid-state batteries,” said El Kazzi. “A few more adjustments – and we could get started.”

Meta Urges Australia to Change Teen Social Media Ban

Tech giant Meta urged Australia on Monday to rethink its world-first social media ban for under-16s, while reporting that it has blocked more than 544,000 accounts under the new law.

Australia has required big platforms including Meta, TikTok and YouTube to stop underage users from holding accounts since the legislation came into force on December 10 last year.

Companies face fines of Aus $49.5 million (US$33 million) if they fail to take "reasonable steps" to comply.

Billionaire Mark Zuckerberg's Meta said it had removed 331,000 underage accounts from Instagram, 173,000 from Facebook, and 40,000 from Threads in the week to December 11.

The company said it was committed to complying with the law.

"That said, we call on the Australian government to engage with industry constructively to find a better way forward, such as incentivizing all of industry to raise the standard in providing safe, privacy-preserving, age appropriate experiences online, instead of blanket bans," it said in statement.

Meta renewed an earlier call for app stores to be required to verify people's ages and get parental approval before under-16s can download an app.

This was the only way to avoid a "whack-a-mole" race to stop teens migrating to new apps to avoid the ban, the company said.

The government said it was holding social media companies to account for the harm they cause young Australians.

"Platforms like Meta collect a huge amount of data on their users for commercial purposes. They can and must use that information to comply with Australian law and ensure people under 16 are not on their platforms," a government spokesperson said.

Meta said parents and experts were worried about the ban isolating young people from online communities, and driving some to less regulated apps and darker corners of the internet.

Initial impacts of the legislation "suggest it is not meeting its objectives of increasing the safety and well-being of young Australians", it said.

While raising concern over the lack of an industry standard for determining age online, Meta said its compliance with the Australian law would be a "multilayered process".

Since the ban, the California-based firm said it had helped found the OpenAge Initiative, a non-profit group that has launched age-verification tools called AgeKeys to be used with participating platforms.

China can narrow its technological gap with the US driven by growing risk-taking and innovation, though the lack of advanced chipmaking tools is hobbling the sector, the country's leading artificial intelligence researchers said on Saturday.

China's so-called "AI tiger" startups MiniMax and Zhipu AI had strong debuts on the Hong Kong Stock Exchange this week, reflecting growing confidence in the sector as Beijing fast-tracks AI and chip listings to bolster domestic alternatives to advanced US technology.

Yao Shunyu, a former senior researcher at ChatGPT maker OpenAI ‌who was named ‌technology giant Tencent's chief AI scientist in December, ‌said ⁠there was a ‌high likelihood of a Chinese firm becoming the world's leading AI company in the next three to five years but said the lack of advanced chipmaking machines was the main technical hurdle.

"Currently, we have a significant advantage in electricity and infrastructure. The main bottlenecks are production capacity, including lithography machines, and the software ecosystem," Yao said at an AI conference in Beijing.

China has completed a working prototype of an extreme-ultraviolet lithography ⁠machine potentially capable of producing cutting-edge semiconductor chips that rival the West's, Reuters reported last month. However, the ‌machine has not yet produced working chips and may ‍not do so until 2030, people with ‍knowledge of the matter told Reuters.

MIND THE INVESTMENT GAP

Yao and other ‍Chinese industry leaders at the Beijing conference on Saturday also acknowledged that the US maintains an advantage in computing power due to its hefty investments in infrastructure.

"The US computer infrastructure is likely one to two orders of magnitude larger than ours. But I see that whether it's OpenAI or other platforms, they're investing heavily in next-generation research," said Lin Junyang, technical lead for Alibaba's flagship Qwen large language model.

"We, ⁠on the other hand, are relatively strapped for cash; delivery alone likely consumes the majority of our computer infrastructure," Lin said during a panel discussion at the AGI-Next Frontier Summit held by the Beijing Key Laboratory of Foundational Models at Tsinghua University.

Lin said China's limited resources have spurred its researchers to be innovative, particularly through algorithm-hardware co-design, which enables AI firms to run large models on smaller, inexpensive hardware.

Tang Jie, founder of Zhipu AI which raised HK$4.35 billion in its IPO, also highlighted the willingness of younger Chinese AI entrepreneurs to embrace high-risk ventures - a trait traditionally associated with Silicon Valley - as a positive development.

"I think if we can improve this environment, ‌allowing more time for these risk-taking, intelligent individuals to engage in innovative endeavors ... this is something our government and the country can help improve," said Tang.
