China on Tuesday called on the U.S. government to urge relevant U.S. 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 U.S. 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-U.S. relations, something not negotiable," said Geng, pointing out that the U.S. side is very clear about this.
"We hope the U.S. government can urge the relevant enterprises to observe the one-China principle and rectify the relevant websites as soon as possible," Geng said.
