Qantas has been ordered to adopt the Chinese Communist Party's view of the world and remove any material from its website that refers to Taiwan as an independent country.

The Australian airline faces the prospect of having its website blocked in what will soon be the world's largest aviation market unless it complies with the demands, which mark an acceleration of a push by China to ensure foreign companies are aligned with its flashpoint "One China" policy.

Chinese authorities have increased pressure on Qantas over how it refers to some destinations.

The Civil Aviation Administration of China, the state airline regulator, sent a letter to Qantas last month telling it to remove any public information that suggests Taiwan, Hong Kong and Macau are part of different countries to mainland China.

Taiwan, an island home to 23 million people, has had a separate government to mainland China since 1949 but Beijing considers it a breakaway province that will one day be reunited with the mainland.
