Some US airlines may change how their websites refer to Taiwan

Four U.S. airlines will reportedly comply with China's demands to change how they refer to Taiwan on their websites.

China said they have to do it by Wednesday.

China doesn't recognize Taiwan as a sovereign nation and threatened airlines with penalties if they said the island was separate from China.

China ordered Taiwan to be listed as "China Taiwan" or the "China Taiwan region." Tapei, the capital of the island, is expected to be listed without mentioning it's in Taiwan.

Several non-U.S. airlines had already complied and made the changes, but four of the airlines in the states — Delta, United, American and Hawaiian — were reportedly holding out.
