BEIJING, June 24 (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.
