The Foreign Ministry has taken countermeasures against two U.S. defense companies for taking part in the United States' arms sale to the Taiwan region.

The two companies are General Atomics Aeronautical Systems and General Dynamics Land Systems, the ministry said in a statement issued on Thursday.
