The one-China principle is the political premise for China's Taiwan region's participation in the World Trade Organization (WTO), Chinese Foreign Ministry spokesperson Lin Jian said on Tuesday.

Lin made the remarks at a regular news briefing when asked to comment on the Taiwan Democratic Progressive Party (DPP) authorities' decision to skip a high-level WTO meeting in Cameroon after Taiwan was listed as a province of China in visa documents.

"The DPP authorities exploited the issue of participating in the meeting for political manipulation, which is utterly despicable. Their attempt to seek independence will only fail and disgrace themselves," Lin said.

There is only one China in the world, and Taiwan is an inalienable part of China's territory, Lin said.

"China's stance has been consistent and clear on the issue of China's Taiwan region participating in the events of international organizations. It must be handled in accordance with the one-China principle," he added.

Lin said the international trade order is facing severe challenges, with unilateralism and protectionism on the rise and the multilateral trading system seriously impacted.

Noting that it is of great significance that the WTO ministerial meeting will return to Africa after a decade, the spokesperson said China firmly supports Cameroon in making it a success.
