China has taken action against two US defense companies, Lockheed Martin and Northrop Grumman, for their involvement in arming Taiwan.
According to the law, the US government is supplying weapons to Taiwan, but China strongly opposes this decision.
China believes that providing weapons to Taiwan threatens its security and sovereignty.
Lockheed Martin was responsible for the recent arms sales to Taiwan, and Northrop Grumman has participated in multiple arms sales.
