SEOUL: The foreign ministers of South Korea, Japan and the United States expressed concern about increasingly frequent destabilising activities around Taiwan in a joint statement after their meeting.

The three also expressed strong opposition to “unlawful maritime claims” in the South China Sea and attempts to enforce such claims, the statement said.

The statement did not specifically mention China, but comes amid simmering tension between Beijing and Washington and its allies over the disputed South China Sea.

China’s foreign ministry said it strongly deplored and opposed the “irresponsible” remarks made by the three countries, urging them to “cease any form of connivance with separatist activities of Taiwan independence.”

Regarding the South China Sea, ministry spokesperson Guo Jiakun said at a press conference that the nations should respect efforts by regional countries to resolve issues through dialogue and consultation, and stop “exaggerating tensions and provoking confrontation.”
