China firmly opposes the latest US bans on new imports of foreign-produced power inverters and advanced robotic devices, and urges Washington to revoke the measures immediately, the Ministry of Commerce said on Thursday.

The move harms others without benefiting the United States itself and constitutes "a typical act of market distortion and unilateral bullying", a spokesperson for the ministry said.

The comments came after the US Federal Communications Commission added the two product categories to its "Covered List" on Tuesday, a move that bars relevant new models from obtaining FCC equipment authorization and entering the US market.

Under the guise of "non-discrimination", the measures in fact discriminate against and suppress Chinese companies and products, the spokesperson said.
