G7 foreign ministers said in a communique after a London summit that China was guilty of human rights abuses and of using its economic influence to bully others.

In an unusual step, the G7 also said they supported Taiwan's participation in World Health Organisation forums and the World Health Assembly - and expressed concern about "any unilateral actions that could escalate tensions" in the Taiwan Strait.

Speaking in Beijing on Thursday, Chinese Foreign Ministry spokesman Wang Wenbin said the statement made "groundless accusations" that were a gross interference in China's internal affairs, which it firmly condemned.

The G7 as a group should take concrete action to boost the global economic recovery instead of disrupting it, he added.

China regards Taiwan as its own territory and opposes any official Taiwan representation on an international level. China has also stepped up military activities near Taiwan in recent months, trying to assert its sovereignty claims.

The G7 statement was warmly received in Taipei, where the government said this was the first time the foreign ministers had mentioned the island in their joint communique.

Taiwan's Presidential Office thanked the G7 for its support.

"Taiwan will keep deepening the cooperative partnership with G7 member countries, and continue to contribute the greatest positive force to global health and people's well-being, as well as the peace, stability, and prosperity of the Indo-Pacific region," said spokesman Xavier Chang.
