China has urged the United States to abide by the one-China principle and to stop the "dangerous moves of arming Taiwan".

China issued the statement in response to the latest U.S. announcement of large-scale arms sales to the Taiwan region.

The Chinese government says it has decided to take countermeasures in accordance with the laws of China on Countering Foreign Sanctions against 20 U.S. military-related companies and 10 senior executives who have engaged in arming Taiwan in recent years.

It states that the US must adhere to three China-US joint communiqués, cease undermining peace and stability in the Taiwan Strait, and stop sending incorrect signals to "Taiwan independence" separatist forces. 

China warns that it will continue to take resolute measures to firmly defend its national sovereignty, security, and territorial integrity.

The Chinese government stresses that the Taiwan question is at the very centre of China’s core interests and is the first red line that must not be crossed in China–U.S. relations. 

It points out that anyone who attempts to cross the line and make provocations on the Taiwan question will be met with China’s firm response. 

It adds that any company or individual who engages in arms sales to Taiwan will pay the price for the wrongdoing. 

The Chinese government's statement says, "No country or force shall ever underestimate the resolve, will, and ability of the Chinese government and people to safeguard national sovereignty and territorial integrity."
