"One China" is a Chinese ideology that recognizes all Chinese-speaking countries as part of China. China still adheres to this "One China" principle for all Chinese-speaking countries, including Taiwan, to this day. The same logic has also been used in Tibet, Xinjiang, and Hong Kong, where China suppressed autonomy and cultural diversity. Instead of love or peace, “One China” has often meant removing differences and justifying control. However, Taiwan still uses the name "Republic of China" and functions as a de facto state. Taiwan's choice to uphold democracy and freedom directly conflicts with China's push for reunification. For decades, the so-called Taiwan Strait Crisis has occurred three times. First Crisis (1954–55) and Second Crisis (1958): China bombarded the islands of Kinmen and Matsu, which Taiwan controlled. The United States responded by deploying the Seventh Fleet and supplying Taiwan with weapons. Third Crisis (1995–96): As Taiwan’s democracy developed and its presidential election approached, China carried out missile tests and large-scale military exercises. The U.S. countered by deploying aircraft carriers. Most recently (2020s): China has continued military drills and psychological pressure around Taiwan, raising fears once again. These crises are more than just military clashes. They show how the “One China” principle has been a constant source of tension. Taiwan’s demand for self-determination is not an emotional rejection of China. It is a rational choice to defend the right of people to live freely and peacefully. Still, a new uncertainty has emerged. After Donald Trump’s reelection, many in Taiwan worry that the United States might not protect them until the end. The core issue in the Taiwan Strait is not great-power rivalry, but the safety and peace of ordinary people. “One China” is not a principle of humanity—it is a slogan for control. True peace cannot come from domination. It can only begin with respect for diversity and freedom.
