China on September 22 declared Taiwan a “red line” ahead of President Xi Jinping’s upcoming summit with U.S. President Donald Trump in Washington. Beijing maintains that Taiwan is an integral part of its mainland and has vowed to integrate the self‑ruled island, warning that any formal ties between Taiwan and countries that recognize it diplomatically would be prohibited.
The Chinese Foreign Ministry described the meeting with Trump as a “milestone of historic significance” and highlighted the centrality of Taiwan in U.S.–China relations. In a front‑page article, the state‑run People’s Daily framed Taiwan independence as a key issue for constructive strategic stability, urging Washington to handle the question with caution and to scale back its proposed $11 billion arms package for Taiwan.
China also monitored Japanese Prime Minister Sanae Takaichi’s planned meeting with Trump, noting that Japan would emphasize the U.S.–Japan alliance and deterrence against what it calls Chinese military and economic coercion. Takaichi’s earlier remarks about a Taiwan contingency as a potential threat to Japan had already strained relations with Beijing.
In addition to diplomatic posturing, China tightened controls on fentanyl precursors, warning companies not to divert medetomidine and tartaric acid into illicit drug production. The move follows U.S. pressure for Beijing to curb chemicals used in the manufacture of the powerful synthetic opioid.
