Cross-Strait relations in the context of "One country, two systems"

The Senkaku Islands, known as the Diaoyu Islands in China and the Diaoyutai Islands in Taiwan, are a group of uninhabited islands in the East China Sea, administered by Japan. They were historically known in the Western world as the Pinnacle Islands. The islands are located northeast of Taiwan, east of China, west of Okinawa Island, and north of the southwestern end of the Ryukyu Islands.

The islands are the focus of a territorial dispute between Japan, China and Taiwan. China claims the discovery and ownership of the islands from the 14th century, while Japan maintained ownership of the islands from 1895 until its surrender at the end of World War II. The United States received administrative rights of the islands from Japan under the Treaty of San Francisco and administered the islands as part of the United States Civil Administration of the Ryukyu Islands from 1945 until 1972, before returning them to Japanese control under the Okinawa Reversion Agreement. The discovery of potential undersea oil reserves in 1968 in the area was a catalyst for further interest in the disputed islands. Despite the diplomatic stalemate between China and Taiwan, both governments agree that the islands are part of Taiwan as part of Toucheng Township in Yilan County. Japan administers the Senkaku islands as part of the city of Ishigaki in Okinawa Prefecture. It does not acknowledge the claims of China nor Taiwan, but it has not allowed the Ishigaki administration to develop the islands.

Chinese unification, also known as Cross-Strait unification or Chinese reunification, is the potential unification of territories currently controlled, or claimed, by the People's Republic of China ("China" or "Mainland China") and the Republic of China ("Taiwan") under one political entity, possibly the formation of a political union between the two republics. Together with full Taiwan independence, unification is one of the main proposals to address questions on the political status of Taiwan, which is the central focus of Cross-Strait relations.
