TAIPEI, Nov 12 (Reuters) - China's increasingly assertive actions in the waters east of Taiwan threaten regional stability and freedom of navigation, G7 foreign ministers said in a joint declaration published late on Wednesday following a meeting in Paris.
China, which views Taiwan as its own territory, has stepped up activity off the island's east coast since June with regular coast guard patrols. Officials in Taiwan, which rejects Beijing's sovereignty claims, say they believe China is practising for a potential maritime blockade using overlapping military, paramilitary and civilian assets.
The G7 statement said the ministers stressed the importance of maintaining peace and stability across the Taiwan Strait.
China's increasingly assertive activities in the waters east of Taiwan "threaten regional stability, freedom of navigation and the safety of international shipping", the statement said.
"We reaffirmed our opposition to any unilateral attempts to change the status quo, particularly by force or coercion, or the threat thereof."
China's foreign ministry did not immediately respond to a request for comment. China recognises no claims of sovereignty by Taiwan.
Following the Chinese Coast Guard's latest patrol off the east coast last month, Taiwan said China was harassing shipping and trying to exert a fictional jurisdiction.
Taipei regards the area off its east coast as critical to wartime supply routes from allies in the event of a blockade or conflict.
The United States, Britain, France and Germany have all previously expressed their concern about China's actions off Taiwan's east coast.
China's military also operates around Taiwan on a daily basis.
China is carrying out "area denial" drills in the Western Pacific involving one of its aircraft carriers and other naval formations, Taiwan Defence Minister Wellington Koo said on Tuesday, following a reported rise in Chinese activities.
China has never renounced the use of force to bring Taiwan under its control, though it says it would prefer "peaceful reunification".
