China Threatens to Cancel Summit if U.S. Approves New Arms Sales to Taiwan

China has warned Washington that a planned summit between President Xi Jinping and President Donald Trump could be canceled if the United States approves additional arms sales to Taiwan. Beijing regards Taiwan as a core interest and a red line in bilateral relations, while Washington says weapons help the island maintain self-defense. The threat comes ahead of negotiations on tariffs, artificial intelligence, and the Iran conflict. The warning underscores how Taiwan continues to complicate efforts to stabilize bilateral ties.
