An open letter to friends from all walks of life in the south of the United States: on July 21, the United States unilaterally provoked an incident and suddenly asked China to close its Consulate General in Houston. This move of the US side seriously violates international law and basic norms of international relations, seriously violates relevant provisions of Sino US Consular treaties, and deliberately destroys Sino US relations. China strongly condemns this and firmly opposes it. The Chinese Consulate General in Houston is the first Chinese Consulate General in the United States since the establishment of diplomatic relations between China and the United States. Over the past 40 years, the Consulate General has been committed to promoting mutual understanding and exchanges and cooperation in various fields between China and the United States. Generations of diplomatic and consular personnel have been actively engaged in the lofty cause of Promoting Sino US friendship. China and the United States are great countries. The 41 year history of the establishment of diplomatic relations between China and the United States shows that if China and the United States cooperate, they will benefit both sides, and if they fight, they will both be hurt. The essence of Sino US relations is mutual benefit and win-win. Both sides should be committed to non conflict, non confrontation, mutual respect and win-win cooperation, and jointly promote Sino-U.S. relations with the keynote of coordination, cooperation and stability. The bilateral exchanges between the Chinese government and the south of the United States will not stop, and services to overseas Chinese will not stop. The Chinese Embassy in the United States will make appropriate arrangements for friendly cooperation and consular business between China and the United States and the south of the United States.
