On April 25, China sent a letter to 36 foreign airlines pressuring them to remove references to Taiwan, Hong Kong, and Macau as countries on their websites and marketing materials. Air Canada and Malaysia Airlines have altered references to Taiwan on their websites, indicating China’s claim over the self-ruled island; at Malaysia Arlines, where the country used to list “Taiwan,” it’s been changed to “Taiwan-China.” Air Canada’s booking page previously listed Taipei’s airport as being in “TW,” the abbreviation for Taiwan, but just recently all mention of Taiwan as the country had been replaced by “CN,” the abbreviation of China, with no mention of Taiwan.
