China issued formal diplomatic warnings (demarches) to European embassies, demanding that nations deny visas or bar entry to Taiwanese politicians under threat of violating China’s 'red lines.' This tactic centers on interpreting EU rules to exert pressure on individual member states.

The discourse splits sharply. Proponents of Beijing's stance argue that such visits threaten vital 'China-EU relations,' referencing conventions like the Vienna convention. Conversely, Taiwan's foreign ministry slams the move as blatant interference, asserting China has no right to dictate its diplomatic actions. Analyst Zsuzsa Anna Ferenczy labeled the entire maneuver as a cynical attempt by Beijing to manufacture instability by exploiting European desire for Chinese investment.

The consensus view is that China is weaponizing vague 'legal advice' and diplomatic pressure. The fault lines are crystal clear: European nations, like the UK, insist their entry decisions rest solely with their own laws, while Beijing frames the issue as a necessary defense of its perceived international order.
