The White House has labelled China's efforts to force foreign airlines to change how they refer to Taiwan, Hong Kong and Macau as "Orwellian nonsense".
Amid a growing fight over US-China trade, the White House said in a statement on Saturday that the Chinese Civil Aviation Administration sent a letter to 36 foreign air carriers, including a number of US carriers, demanding changes.
The carriers were told to remove references on their websites or in other material that suggests Taiwan, Hong Kong and Macau are part of countries independent from China, US and airline officials said.
The White House said President Donald Trump "will stand up for Americans resisting efforts by the Chinese Communist Party to impose Chinese political correctness on American companies and citizens.
"This is Orwellian nonsense and part of a growing trend by the Chinese Communist Party to impose its political views on American citizens and private companies."
Taiwan is China's most sensitive territorial issue. Beijing considers the self-ruled, democratic island a wayward province. Hong Kong and Macau are former European colonies that are now part of China but run largely autonomously.
"The United States strongly objects to China's attempts to compel private firms to use specific language of a political nature in their publicly available content," the White House said in its statement. "We call on China to stop threatening and coercing American carriers and citizens."

The sharp criticism comes on the heels of contentious trade talks with China earlier this week.
The Trump administration demanded a $US200 billion cut in China's trade surplus with the United States by 2020, sharply lower tariffs and a halt to subsidies for advanced technology, people familiar with the talks said on Friday.
Trump tweeted on Friday that he would meet with US trade officials once they returned from their meetings in China. "It is hard for China in that they have become very spoiled with US trade wins!" Trump wrote.
On Saturday, a spokesman for Airlines for America, a trade group representing United Airlines, American Airlines and other major carriers, said the group was "continuing to work with US government officials as we determine next steps" over China's demands on how airlines refer to Hong Kong, Taiwan and Macau
In January, Delta Air Lines, following a demand from China over listing Taiwan and Tibet as countries on its website, apologised for making "an inadvertent error with no business or political intention", and said it had taken steps to resolve the issue.
Qantas Airways said in January it had amended its website to no longer refer to Taiwan and Hong Kong as countries, rather than Chinese territories after China issued a similar warning.
Also in January, China suspended Marriott International's Chinese website for a week to punish the world's biggest hotel chain for listing Tibet, Taiwan, Hong Kong and Macau as separate countries in a customer questionnaire.
