BEIJING - China on Tuesday called on the US government to urge relevant US airlines to observe the one-China principle.

Chinese Foreign Ministry spokesperson Geng Shuang made the remarks at a press briefing in response to a question regarding US airlines not having changed their listing of Taiwan on their websites.

In late April, China's civil aviation authority sent a formal notice to 44 foreign airlines, asking them to list Taiwan as part of China on their websites.

"The one-China principle represents the consensus shared by the international community and is the political foundation for the steady development of China-US relations, something not negotiable," said Geng, pointing out that the US side is very clear about this.

"We hope the US government can urge the relevant enterprises to observe the one-China principle and rectify the relevant websites as soon as possible," Geng said.
