Nvidia Corp. said the US government is restricting the export of its H20 chip to China, hamstringing a product line that the company had designed to meet previous curbs.

The government informed Nvidia on Monday that the H20 would require a license to export to China “for the indefinite future,” the company said in a regulatory filing Tuesday. The government said that the new rules address concerns that “the covered products may be used in, or diverted to, a supercomputer in China.”
