The current Director General of the secretariat, Peter Forau, refers to the creation of the MSG trade agreement as a milestone for the group and an indicator of its success. It was signed in 1993 by Papua New Guinea, Solomon Islands and Vanuatu. Fiji joined in 1998. From 24 to 26 June 2015, the summit of Member States in Honiara, Solomon Islands, ended with important decisions; Indonesia was elevated to the rank of associate member of the group, making it the official representative of the West Papua region, while the ULMWP (United Nations Liberation Movement for West Papua) remained an observer.   ULMWP was considered only as the representative of the West Papuans outside the country.  The secretariat of the Melanesian Spearhead Group was established in May 2008, after years of activity, on an ad hoc basis. The opening of a permanent office in Port Vila, Vanuatu, marked a new phase for the MSG Group, as it dared to organize and manage its business in a more structured way.  In addition to the MSG trade agreement, there are a number of projects and activities underway within the secretariat and under the direction of the political leadership. There are several economic activities, including the development of a system of transfer of skills to facilitate the immigration of labour between Member States. At its recent summit in 2013, MSG took the innovative initiative of creating a peacekeeping unit to explore ways to make UN peacekeeping missions available to members of the group in other parts of the world. Because of the ideals of solidarity of the founders of Melanesian, MSG participates in a number of projects, from commercial agreements to sports programs. It also conducts region-specific research and publishes reports on topics such as fisheries management, up to „alternative indicators of well-being for Melanesia.“ Concerned about its performance, MSG commissioned a group of delegates to verify their progress since its inception and to develop an action plan to maximize their performance by 2038.
Under the title „MSG 2038 Prosperity for All Plan“, its main solution is to further improve Melanesian sub-regionalism by strengthening cooperation, integration and service delivery. The Organization is encouraged to continue to cooperate with other international organizations. Strengthening sub-regionalism does not require a step back on initiatives. The report focuses on the integration of traditional knowledge, which remains an important commonality between Member States.
