The U.S. government has granted an annual licence to Taiwan Semiconductor Manufacturing

to import U.S. chip manufacturing equipment to its facilities in Nanjing, China, the chipmaker said on Thursday.

The approval “ensures uninterrupted fab operations and product deliveries,” the company said in a statement to Reuters.

South Korea’s Samsung Electronics and SK Hynix have also received similar import licences.

Previously, the Asian companies had benefited from exemptions from Washington’s sweeping restrictions on chip-related exports to China, part of U.S. efforts to try to stay ahead of China in technological development.
