When the US administration amped up trade rhetoric on China, China began squeezing US companies especially ones with visible brands. Marriott fired a social media employee who ‘liked’ a Friends of Tibet tweet, and even self-reported a banned book in the lobby of one of its hotels. China has insisted travel companies not list Taiwan as a separate country.
Of course, they’ve largely complied. US airlines though haven’t gone so far as to identify Taiwan as explicitly part of China as many world airlines have. Indeed US airlines are trapped between their Chinese regulators and needing to appease the government at home which has publicly rebuked China for attempting to regulate US corporate speech.
