TAIPEI: Taiwan said Friday it had been blocked by China from attending a major United Nations aviation meeting, the latest setback to its troubled campaign for international recognition. Self-ruling Taiwan is routinely prevented from attending global forums by Beijing, which still sees it as part of its territory requiring reunification. But the island had been hoping to attend the triennial meeting of the UN aviation agency in Montreal later this month, after it was admitted in 2013 in a major breakthrough. That invite came under previous Beijing-friendly president Ma Ying-jeou. But ties with China have rapidly turned frosty under new leader Tsai Ing-wen who took office in May. Taiwan’s Mainland Affairs Council (MAC), which handles relations with Beijing, said Friday the island had not been admitted to the International Civil Aviation Organization (ICAO) meeting “due to political interference from China”. “(It) is a great loss for international aviation safety and the public’s right to welfare protection,” the MAC said in a statement. Taiwan was a founding member of the ICAO but was thrown out in 1971 when it lost its UN seat to China.
