BEIJING (Reuters) - China is gravely concerned and firmly opposed to U.S. proposed rules for curbing certain investments in China, and reserves the right to take corresponding measures, the Chinese commerce ministry said on Monday.

The U.S. should "stop politicising and weaponising economic and trade issues, and lift investment restrictions on China," the ministry said in a statement.

Washington issued on Friday draft rules for banning or requiring notification of certain investments in artificial intelligence and other technology sectors in China that could threaten U.S. national security.
