China has imposed sanctions on seven military industrial firms and their senior executives in response to U.S. arms support and sales to Taiwan, as announced by the Chinese foreign ministry on Friday. Among the companies identified are Insitu Inc., a subsidiary of Boeing, as well as Raytheon Canada and Raytheon Australia, both part of RTX Inc., along with Hudson Technologies Co.

Recently, the U.S. authorized $571.3 million in defense assistance for Taiwan, following a prior approval of arms sales estimated at $385 million.

China regards Taiwan, which operates as a democratic entity, as part of its territory and has not ruled out the use of force to assert control over the island. Taiwan firmly rejects China’s claims of sovereignty, asserting that only its citizens have the right to determine their future. Despite the absence of formal diplomatic relations between the U.S. and Taiwan, U.S. law mandates that Washington provide Taiwan with the means for self-defense.

The sanctions will result in the freezing of assets belonging to the companies and executives within China, and will prohibit Chinese entities and individuals from engaging in trade or collaboration with them, according to the ministry’s statement. A spokesperson for the ministry remarked that the U.S. actions “seriously undermine China’s sovereignty and territorial integrity.” The spokesperson, Mao Ning, urged the U.S. to adhere to the one-China principle and cease military support for Taiwan, emphasizing that Beijing will “take all necessary measures” to protect its security and interests.
