US tightens AI exports

House lawmakers moved this week to tighten U.S. restrictions on artificial intelligence exports to China, opening a new fight over Nvidia chips and overseas cloud access. (bloomberg.com) The House Foreign Affairs Committee advanced a bipartisan package on April 22, including the AI Overwatch Act, as members from both parties said current rules still leave loopholes for powerful U.S. technology to reach Chinese users. (bloomberg.com) (foreignaffairs.house.gov) Commerce Secretary Howard Lutnick said on April 22 that Nvidia’s H200 chips have not been sold to Chinese companies, even after the Trump administration in January gave conditional approval for those exports. He said Chinese government approval has been one obstacle. (yahoo.com) (congress.gov) At stake is a narrow part of the chip market with outsized military and commercial value. Advanced semiconductors are the computing engines behind large artificial intelligence models, and Congress’s research arm says U.S. policy since 2018 has aimed to slow China’s access to those systems and the supply chain around them. (congress.gov) The dispute sharpened after the White House’s December 2025 plan to let Nvidia sell H200 chips to China in exchange for a 25% payment tied to imports from Taiwan fabrication sites. Congress’s legal analysts said the arrangement relied on a new export-license rule and a Section 232 tariff. (congress.gov) House China hawks have spent April arguing that China is still finding ways to buy, smuggle, or otherwise obtain frontier artificial intelligence hardware. An April 16 report from the Select Committee on the Chinese Communist Party said China remains the largest market for chipmaking equipment despite existing restrictions. (chinaselectcommittee.house.gov) That campaign has not been limited to physical chips. The AI Overwatch Act was introduced in January with language aimed at blocking adversary militaries from getting “weapon-enabling AI” while speeding exports to U.S. allies and partners. (foreignaffairs.house.gov) Industry and the White House now face pressure from both sides: some lawmakers want harder limits, while some stakeholders argue broader controls could cut U.S. sales without stopping Chinese development. A Congressional Research Service report published in September 2025 said that split has defined the debate over whether stricter controls protect U.S. advantages or give up revenue and market share. (bloomberg.com) (congress.gov) The next test is whether these committee bills can clear Congress and survive White House resistance. For now, the practical signal is narrower: even with formal approval on paper, Nvidia’s H200 still has not reached Chinese buyers. (bloomberg.com) (yahoo.com)
