A spokesperson for China's foreign ministry said Beijing would take "all necessary measures" and warned the U.S. that Taiwan is "a red line that must not be crossed," Reuters reported. The aid package totals $571 million.

A Chinese Foreign Ministry statement urged the U.S. to stop arming Taiwan and stop what it called “dangerous moves that undermine peace and stability in the Taiwan Strait.” U.S. military sales and assistance aim to help Taiwan defend itself and deter China from launching an attack.

President Biden authorized an additional $571 million in funding to Taiwan for military aid, prompting China to send a staunch warning to the U.S. to stop arming Taiwan.
