Sen. Tom Cotton (R-Ark.) on Wednesday introduced legislation that would block the U.S. from sharing intelligence with countries that use technology from Chinese telecommunications giant Huawei in their fifth-generation (5G) networks.

“The United States shouldn’t be sharing valuable intelligence information with countries that allow an intelligence-gathering arm of the Chinese Communist Party to operate freely within their borders,” the senator said in a statement after introducing the less-than-two-page bill.

“I urge our allies around the world to carefully consider the consequences of dealing with Huawei to their national interests.”

The bill comes as the Trump administration has stepped up efforts get Huawei out the U.S. and to dissuade allies from relying on hardware and software from the company, which it has called a national security threat because of ties to the Beijing ruling party.

The Department of Commerce placed Huawei on its blacklist in May, preventing U.S. firms from conducting business with the telecommunications giant unless they obtain a specific license.
