China on Wednesday urged relevant parties to earnestly honor the one-China principle and stop offering stages for "Taiwan independence" separatist forces, said a Chinese Foreign Ministry spokesperson at a regular press briefing.

Spokesperson Guo Jiakun made the remarks after Taiwan leader Lai Ching-te addressed the Copenhagen Democracy Summit via video link.

"The so-called Copenhagen Democracy Summit is filled with ideological biases. The summit repeatedly invited 'Taiwan independence' separatist forces to make irresponsible remarks, posing a severe violation of the one-China principle. China firmly opposes it," he said.
