The Strait mostly separated the
Han culture of the Chinese mainland from
Taiwan Island's
aborigines for millennia, although the
Hakka and
Hoklo traded and migrated across it.
European explorers, principally the
Portuguese,
Spanish and
Dutch, also took advantage of the strait to establish forward bases for trade with the mainland during the
Ming; the bases were also used for
raiding both the Chinese coast and the trading ships of rival countries. Widespread Chinese migration across the strait began in the late
Ming. During the
Qing conquest, Zheng Chenggong (
Koxinga) expelled the Dutch and established the
Kingdom of Tungning in 1661, planning to launch a reconquest of the mainland in the name of the
Southern Ming branches of the old imperial dynasty.
Dorgon and the
Kangxi Emperor were able to consolidate their control over southern mainland China; Koxinga found himself limited to raiding across the strait. His grandson
Zheng Keshuang surrendered to the Qing after his admiral lost the 1683
Battle of the Penghu Islands in the middle of the strait.
Japan seized the
Penghu Islands during the
First Sino-Japanese War and gained control of Taiwan at its conclusion in 1895. Control of the eastern half of the strait was used to establish control of the southern Chinese coast during the
Second World War. The strait protected Japanese bases and industry in Taiwan from Chinese attack and sabotage, but
aerial warfare reached the island by 1943. The 1944
Formosa Air Battle gave the
United States Pacific Fleet air supremacy from its
carrier groups and
Philippine bases; subsequently, the bombing was continuous until
Japan's surrender in 1945. The
rapid advance of the
Communist PLA in 1949 provoked the government's
retreat across the Taiwan Strait. In the aftermath of the
Chinese Civil War,
People's Republic of China and
Republic of China had multiple brief armed conflicts on the Taiwan Strait, consequently named the
First Taiwan Strait Crisis, the
Second Taiwan Strait Crisis, and the
Third Taiwan Strait Crisis. These confrontations did not result in large-scale military conflicts between China and Taiwan. In the 21st century, the
Cross-Strait relations stabilized, leading to the establishment of
Three Links on 15 December 2008, with the commencement of direct commercial flights, shipping, and post across the Taiwan Strait. On 25 May 2002,
China Airlines Flight 611 broke up in mid-air and crashed into the Taiwan Strait, killing all 225 people on board. On 26 February 2022, China denounced the sailing of the U.S. Navy's
7th Fleet guided-missile destroyer through the Taiwan Strait as a "provocative act". Since 2018
China has denied that the concept of
international waters applies to the Taiwan Strait. China does not claim sovereignty over the entire strait but seeks to regulate what it views as "support for the Taiwan authorities and muscle-flexing against the mainland". This position has led to concerns from American, Australian, and French officials and objection from Taiwan. "International waters" is technically not defined by the
United Nations Convention on the Law of the Sea, and there is no high seas corridor within the Taiwan Strait, but transit rights mimicking high seas such as
innocent passage and
freedom of navigation are generally allowed within
exclusive economic zones. == Economy ==
