Taiwan (Chinese: Táiwān) is an island in the western Pacific separated from mainland China by the Taiwan Strait, governed since 1949 by the Republic of China (ROC) government that retreated there following defeat by the Chinese Communist Party in the Chinese Civil War. The island was ceded by Qing China to Japan under the Treaty of Shimonoseki (1895) and returned to ROC control in 1945 after Japan's defeat, an arrangement the PRC traces to the Cairo Declaration (1943) and the Potsdam Declaration (1945). The People's Republic of China, established on 1 October 1949, claims sovereignty over Taiwan under its One-China principle and the Anti-Secession Law (2005), which authorises "non-peaceful means" should Taiwan formally declare independence. The ROC, conversely, has functioned as a self-governing democracy since martial law was lifted in 1987 and direct presidential elections began in 1996.
The international status of Taiwan turns on the distinction between the "One-China principle" (Beijing's position that there is one China and Taiwan is part of it) and the "One-China policy" adopted by states such as the United States, which merely "acknowledges" Beijing's position without endorsing it. UN General Assembly Resolution 2758 (1971) expelled the ROC and seated the PRC as "the only legitimate representative of China," though it did not explicitly settle Taiwan's sovereignty. The United States switched recognition from Taipei to Beijing on 1 January 1979, governing relations thereafter through the Taiwan Relations Act (1979), the Three Joint Communiqués, and the Six Assurances. As of 2026, Taiwan maintains formal diplomatic relations with roughly a dozen states and participates in bodies like APEC and the WTO under the name "Chinese Taipei."
Cross-strait relations have oscillated between engagement and confrontation. The "1992 Consensus"—an ambiguous formula of "one China, different interpretations"—underpinned warming ties under President Ma Ying-jeou (2008–2016), culminating in the Xi–Ma meeting in Singapore in November 2015. Relations cooled sharply under the Democratic Progressive Party administrations of Tsai Ing-wen (2016–2024) and Lai Ching-te (from 2024), whom Beijing regards as separatists. Tensions spiked after US House Speaker Nancy Pelosi's visit in August 2022, which triggered unprecedented PRC military exercises encircling the island. Taiwan's strategic salience is magnified by its dominance of advanced semiconductor manufacturing through TSMC, making it central to global supply chains.
For competitive examinations, Taiwan recurs in International Relations and World History papers (UPSC GS-II, FSOT, CSS Current Affairs). Examiners test the legal nuances of Resolution 2758, the difference between One-China "principle" and "policy," the contents of the Taiwan Relations Act and Anti-Secession Law, and the historical chain from Shimonoseki through Cairo to 1949. A frequent analytical angle asks candidates to assess Taiwan as a flashpoint in US–China rivalry and its implications for Indo-Pacific security, the QUAD, and semiconductor geopolitics. Precision on dates and instruments distinguishes high-scoring answers from vague narratives.
Example
In August 2022, US House Speaker Nancy Pelosi visited Taipei, prompting the People's Liberation Army to launch its largest-ever military exercises encircling Taiwan and to suspend several dialogue channels with Washington.
Frequently asked questions
The One-China principle is Beijing's assertion that there is one China and Taiwan is part of it. The One-China policy is the position of states like the US that merely 'acknowledges' Beijing's claim under the Three Joint Communiqués without explicitly endorsing PRC sovereignty over Taiwan.
