Howard Lutnick, U.S. Secretary of Commerce speaks during the Pennsylvania Energy And Innovation Summit 2025 at Carnegie Mellon University in Pittsburgh on July 15, 2025. Commerce Secretary Howard Lutnick on Tuesday said the Trump administration reversed course on allowing Nvidia to sell its AI chips to China because the U.S. company will not be giving over its best technology. Lutnick made the remark speaking with CNBC's Brian Sullivan, saying that Nvidia wants to sell China its "4th best" chip, which is slower than the fastest chips that U.S. companies use. "We don't sell them our best stuff, not our second best stuff, not even our third best," Lutnick said. Nvidia said Monday night that it would soon resume sales of the H20 chip to China after the Trump administration signaled that it would grant the chipmaker necessary export licenses. Lutnick said that the administration said that the renewed sale of H20 chips to China was linked to a rare-earths magnet deal. Lutnick said it was in U.S. interests to have Chinese companies using American technology so they continue to use an American "tech stack." "The fourth one down, we want to keep China using it," Lutnick said. "We want to keep having the Chinese use the American technology stack, because they still rely upon it." Similarly, Nvidia CEO Jensen Huang has said in recent weeks that the U.S. should continue selling his chips to China so Chinese companies don't invest in homegrown infrastructure. Huang on Sunday also said that the Chinese military wouldn't use Nvidia chips anyway, and previously signaled that China's Huawei is a legitimate competitor. "The idea is the Chinese are more than capable of building their own," Lutnick said. "You want to keep one step ahead of what they can build, so they keep buying our chips." The reversal is a major win for Nvidia. Huang had previously said that the Trump administration's decision to require a license for the H20 chip in April "effectively closed" the China market. Nvidia said that it could have sold $8 billion in H20 chips in the current quarter before sales were stopped.
