Chinese ambassador to the United States, Qin Gang, said Saturday that the U.S.'s attempt to use the Taiwan question to contain the Chinese mainland will only shoot itself in the foot.

The ambassador made the remarks in a virtual message delivered at the 2021 annual meeting of the Alliance for China's Peaceful Reunification in San Francisco.

Qin pointed out that Taiwan's Democratic Progressive Party (DPP) authority have been inciting cross-Strait confrontation, colluding with external forces and making provocations for "independence."

These acts have seriously harmed the fundamental interests of the Chinese nation and the vital interests of Taiwan compatriots and seriously jeopardized the peace and stability across the Taiwan Straits, Qin said.

Qin said, "we will redouble our efforts to promote the integrated development of the Taiwan Straits, but we make no promise to renounce the use of force and reserve the option of taking all necessary means."

Qin urged the U.S. to abide by the one-China principle and its commitment to China, handle the Taiwan question prudently and properly, and avoid any conflict and confrontation between the two countries caused by the Taiwan question.

Qin also fully affirmed the Alliance for China's Peaceful Reunification's contributions and its opposition to "Taiwan independence" separatist activities, promotion of peaceful reunification and the peaceful development of cross-Strait relations.
