U.S. lawmakers are calling on President Donald Trump’s administration to consider imposing new export controls on Nvidia’s AI chips, particularly the H20 model, which they allege is being used by China’s AI company DeepSeek. Republican John Moolenaar and Democrat Raja Krishnamoorthi, co-chairs of the House of Representatives Select Committee on China, sent a letter to National Security Advisor Michael Waltz urging a review of the U.S. export control system.
The lawmakers expressed concern that the H20 chip, which is not currently covered by existing U.S. export restrictions, is being used in DeepSeek’s newly released sophisticated AI model. This comes amid growing concerns in Washington over China’s rapid advancements in AI. DeepSeek, which recently launched a free AI assistant, claims its technology uses significantly less data and is far more cost-effective than incumbent models, potentially marking a shift in the AI investment landscape.
In addition to the lawmakers’ letter, the U.S. House of Representatives’ Chief Administrative Officer notified offices not to use DeepSeek’s technology, citing an ongoing review. The U.S. government has long been concerned that China could leverage AI for cyberattacks or even bioweapons development, prompting former President Joe Biden to initiate measures to limit China’s access to AI chips.
Nvidia responded, stating that its products comply with all U.S. regulations and that the company is open to collaborating with the administration on AI-related matters.
