The five-member FCC said it has voted unanimously to adopt new rules that will block the importation or sale of certain technology products that pose security risks to U.S. critical infrastructure.

Chinese telecom equipment giant Huawei is the world's third-largest seller of smartphones, and a few powerful senators say they want to ban it entirely from the U.S. amid national security concerns.

A bipartisan amendment by Senators could undo a deal struck days ago to revive the Chinese telecoms giant after it was cut off from its U.S. suppliers over sales to Iran and North Korea.

The cellphone maker was sanctioned by the Commerce Department for illegal sales to Iran and North Korea. However, President Trump last month said he wanted to resolve the issue to save jobs in China.

Trump says he is working with Chinese President Xi Jinping to get cellphone-maker ZTE "back in business" after it was punished for selling U.S. technology to Iran and then violated a settlement.
