Zhang Jun, the Chinese ambassador to the United Nations, asserted that if U.S. House Speaker Nancy Pelosi visits Taiwan, it will harm U.S.-China relations. Zhang stated at a press conference that Pelosi's visit to Taiwan "will undermine the relationship between China and the United States." He added that "Washington must understand the consequences of such a step," emphasizing that "Taiwan is an inseparable part of China, and the issue of territorial unity is a red line for Beijing." He continued: "We do not allow anyone to cross this red line, and we strongly oppose any separatist movements in Taiwan, as well as interference in China’s internal affairs."
