The Chinese foreign ministry said on Monday (September 19) that China has lodged "stern representations" with the United States, after U.S. President Joe Biden said U.S. forces would defend Taiwan in the event of a Chinese invasion, Reuters reports.
China reserves the right to take all necessary measures in response to activities that split the nation apart, said Mao Ning, spokesperson at the foreign ministry, at a regular media briefing.
She also urged the U.S. to handle Taiwan-related issues "in a prudent and proper manner" and not send "wrong signals" to Taiwan independence separatist forces, warning the United States not to seriously damage Sino-U.S. relations and the peace in the Taiwan Strait.
