The island of Taiwan belonged to China at some point. No political statement needed and no need to rewrite history on HN comments.
Historically, Taiwan was governed by Chinese administrations for a significant period. In 1683, after defeating the Ming loyalists in Taiwan, the Qing dynasty extended its rule over the island, eventually incorporating it as part of its empire. By 1887, Taiwan was officially designated a province of China under Qing rule. However, following the First Sino-Japanese War, Taiwan was ceded to Japan in 1895. After World War II, Taiwan was placed under the administrative control of the Republic of China. Today, its status remains politically and historically complex, with ongoing debates over sovereignty.
