  A little history. Prior to 1972, the United States had no diplomatic with The Peoples Republic of China.   In 1971 President Nixon wanted to leave his mark on history so badly, he complied with every demand China asked so he instructed his Secretary of State to make the "Shanghai Gesture" which had the United States state public that Taiwan  was not a sovereign nation but belonged solely to the The Peoples Republic of China. A treaty violation.  Less than a month later in 1971 President Nixon also instructed the United States Ambassador to the UN not exercise a US Security Council veto for the expulsion of the then sovereign nation of Taiwan.
