In 1911, the Republic of China (ROC) was established by Sun Yat-sen and the Nationalist (Kuomintang) party.That said, the ending of the hostility between the US and the PRC in the early 1970s (the US also switched its diplomatic recognition from the ROC to the PRC in 1970, the UN admitted the PRC and ejected the ROC in 1971) wasn't the whole story.
In 1949, the civil war between the Nationalists, then led by Chiang Kai-shek, and the Communists, led by Mao Tse-tung, ended with the defeat of the Nationalists and the retreat of the ROC to Taiwan, and the establishment of the People's Republic of China (PRC) by the Communists. (There were considerable repercussions in domestic politics in the US, with McCarthy claiming that the Communist victory in China was due to treason on the part of the Truman government.)
Thus as of 1949, there were two states which formally claimed sovereignty over the entirety of Chinese territory: the ROC, which only controlled Taiwan, and the PRC, which controlled mainland China but not Taiwan. Formally, this is still true.
It's a delicate situation, because the PRC still claims sovereignty over Taiwan. It's unclear what US policy is: would it go to war with the PRC to prevent reunification? Is an independent Taiwan really a vital interest of the US? (My answer would be no.) See this debate between Charles Freeman and Arthur Waldron.
In common usage, "China" refers to the PRC, and "Taiwan" refers to the ROC.
The change, effective in the paper of March 5, follows the adoption of the system by the Chinese Government for news reports sent abroad. Since Jan. 1, the system has been consistently used in press dispatches and Government pronouncements originating in China and transmitted in English through the official New China News Agency and other publications. These now refer to Teng Hsiao-ping, the Deputy Prime Minister, as Deng Xiaoping, and to Mao Tse-tung as Mao Zedong.
The new system, known as Pinyin, for the Chinese word meaning "transcription," has been adopted in the United Nations and by the United States Board on Geographic Names, which determines the spelling of place names for Government use.
The Times delayed adoption to allow cross-referencing of names in its clipping, picture and map files and in its computerized Information Bank.
