Chinese ambassador to the United States Qin Gang on the 13th urged the United States to abide by the one China principle and its commitments to China, handle the Taiwan issue cautiously and properly, and guard against Sino US conflicts and confrontation caused by the Taiwan issue. Qin Gang congratulated the 2021 annual meeting of the all American Federation for the promotion of China's peaceful reunification in San Francisco by video. In his speech, he fully affirmed the positive contributions made by the Association for a long time to curb and oppose "Taiwan independence" separatist activities, maintain the peaceful development of cross-strait relations and promote China's reunification. Qin Gang pointed out that at present, Taiwan's Democratic Progressive Party authorities are inciting cross-strait confrontation, colluding with external forces, constantly carrying out provocations for "independence", and are gradually coerced the Taiwan people into the "Taiwan independence" chariot. These acts seriously harm the fundamental interests of the Chinese nation and the vital interests of Taiwan compatriots, and seriously endanger peace and stability in the Taiwan Strait. We are willing to redouble our efforts to promote the development of cross-strait integration, but we will never promise to give up the use of force and reserve the option of taking all necessary measures. The United States continues to manipulate the Taiwan issue in an attempt to "use Taiwan to control China", which is bound to lift a stone and hit itself in the foot. (outlook new era)
