Many small island developing countries concentrated in the South Pacific, and the South Pacific island countries present stereotype specificities of small island developing countries. In recent years, the United States has stressed reengagement with affairs in the AsiaPacific, Australia has intended to consolidate its leadership in the area, and Taiwan has tried to enlarge its influence as the “diplomatic alliance” in this area, all of which give rise to the intensified game among concerned parties. Considering specificities of small island countries in the South Pacific and complexity of game among powers, the implement of the Belt and Road Initiative in the area should put more emphasis on multilateral diplomacy and summit diplomacy; adjust the aid method and stress the assessment of effect to realize precise aid; enhance peopletopeople exchanges and public diplomacy; promote environmental cooperation and maritime cooperation. By virtue of strategic synergy and cooperation with countries along the Belt and Road, China should establish the allround, multitiered and wideranging blue partnership with the aim to push ahead with the joint construction of the blue economic passage linking China, Oceania, and the South Pacific.
