Taiwan’s latest diplomatic push in the Pacific has come with developments in maritime infrastructure. Between 2024 and 2025, Taiwan pushed the number of high-voltage shore power systems at its ports to 11, relaunched a solar-powered research yacht for Palau, and helped finance Tuvalu’s first international submarine internet cable. These initiatives underscore a deliberate strategy: Taipei is leveraging green-technology projects and sustainable infrastructure as diplomatic levers. By exporting port-based renewables and connectivity, Taiwan hopes to cement ties with allied nations—at a time when climate change and economic development are urgent challenges among the Pacific island states.
