All countries maintaining diplomatic relations with China have, in conformity with international law and the principle of one China, undertaken in formal agreement or understanding with the Chinese Government not to establish any ties of an official nature with Taiwan. According to international law, a sovereign state can only be represented by a single central government. All the countries maintaining diplomatic relations with China have recognized that the Central People's Government of the People's Republic of China is the sole legal government representing the whole of China, and also recognized or respected the position of China that there is only one China in the world and Taiwan is a part of China. Therefore, as a part of China, Taiwan has no right whatsoever to represent China, nor can it establish "diplomatic ties" or enter into relations of an official nature with foreign countries.
