Leaders of 18 Pacific island nations and areas agreed to an enhanced role of Japan in the region's development while opposing any attempted coercive activity, in a joint declaration adopted at their summit Thursday, as Tokyo seeks greater engagement to counter China's influence.

The Pacific Islands Leaders Meeting, or PALM, launched under a Japanese initiative in 1997, has become Japan's key diplomatic tool to deter China's security and economic influence in the region by strengthening its ties with the Pacific Island Forum members, stressing its willingness to stand by them and maintaining unity as an equal partner.
