Papua New Guinea and Solomon Islands have reaffirmed their commitment to closer economic cooperation, with trade, investment, transport and resource development emerging as central themes during talks between Prime Minister James Marape and Solomon Islands Prime Minister Jeremiah Manele in Port Moresby in June.
While security and regional cooperation featured prominently in the leaders’ discussions, both governments placed considerable emphasis on expanding commercial links between the two Melanesian neighbours. The meeting reviewed progress on bilateral trade, shipping and aviation connectivity, labour mobility and opportunities to deepen cooperation in mining, fisheries and agriculture. The leaders also reaffirmed their commitment to improving the movement of goods, services and people across the shared maritime region.
For businesses, the discussions reflect a broader shift towards greater regional economic integration within the Pacific. Papua New Guinea is Solomon Islands’ largest Melanesian economy and an increasingly important source of investment, technical expertise and commercial partnerships. Stronger transport links and streamlined trade arrangements have the potential to lower business costs and improve supply chains for exporters, importers and tourism operators in both countries.
Mining was one area identified for closer collaboration. Prime Minister Marape said Papua New Guinea was willing to share its experience in developing a modern mining industry and welcomed opportunities for PNG companies to participate in future resource projects in Solomon Islands. Such cooperation could create opportunities for engineering firms, contractors, training providers and professional services businesses with experience in the resources sector.
The leaders also discussed fisheries, recognising the importance of sustainable management of one of the Pacific’s most valuable economic resources. Expanded cooperation in fisheries management and processing has the potential to strengthen exports while creating employment and supporting downstream industries.
Trade between the two countries remains modest by global standards but is expected to grow as transport connections improve and businesses seek opportunities beyond their domestic markets. Closer engagement also supports wider regional initiatives under the Melanesian Spearhead Group and the Pacific Islands Forum, where economic resilience and private sector development have become increasing priorities.
For Papua New Guinea, stronger commercial ties with Solomon Islands reinforce its role as an economic leader in Melanesia. For businesses operating across the region, the June discussions signal continued government support for investment, regional commerce and cross-border partnerships.
