One of the most prompt arguments about Taiwan’s international legal status is its lack of recognition by the United Nations. When the United Nations was formed, the Republic of China was one of five permanent seats. After 1949, the Chinese Nationalist Party and the Republic of China fled mainland China to establish itself in Taiwan. To many, this marked the end of the Chinese Civil War and saw the People’s Republic of China and the Chinese Communist Party to the representative of China.
In adherence to the One China Policy, in 1971, United Nations passed Resolution 2758:
This resolution removed the Republic of China as the legitimate representative of China. The permanent seat at the security council was given to the representative from People’s Republic of China.
Taiwan, Province of China
Many times “Taiwan, Province of China” will be found in drop-downs in many forms. This is because most systems take up the list of countries from ISO-9001. This is a United Nations standard for the list of countries. Evidently, this lists Taiwan as a province of China as it does not recognize Taiwan as a country. An alternative to ISO-9001 is ISO-3166 which are “codes for the representation of names of countries and their subdivisions”, which would display “Taiwan” independently. This list does not designate if each code is a country or a subdivision.
