The Foreign Ministry stated Beijing's firm objection on Thursday after the United States Federal Communications Commission said it is planning to vote on a proposal that would ban all Chinese labs from testing electronic devices used in the US.

"China firmly opposes the approach taken by the US in excessively broadening the concept of national security," Foreign Ministry spokeswoman Mao Ning said at a daily news conference in Beijing on Thursday.

This approach severely obstructs normal economic and trade exchanges between Chinese and US companies and is not in the interests of parties including US businesses and consumers, she said.

China will continue to resolutely safeguard its legitimate rights and interests, she added.
