The Embassy of the People's Republic of China in Estonia has formally protested the attendance of Estonian lawmakers at a National Day event for Taiwan held in Tallinn. A diplomatic note was delivered to the Riigikogu, Estonia’s parliament, expressing China’s disapproval. This protest underscores China’s sensitivity regarding international recognition of Taiwan, which it views as a renegade province. The event in Tallinn celebrated Taiwan’s National Day, a move likely perceived by Beijing as supportive of Taiwanese independence. This incident highlights the complex diplomatic relationship between China, Estonia, and Taiwan. It demonstrates China’s willingness to engage in diplomatic pressure when it perceives its core interests are challenged in countries like Estonia. The Estonian government has not yet publicly responded to the formal protest.
