Pacific leaders have just heard from US president Joe Biden who's imploring them to maintain a free and open Indo-Pacific - saying it's vital to regional security and prosperity. A virtual meeting of the Pacific Islands Forum is under way today. High on the agenda: climate change, Covid-19, and the nexus of geopolitics and security. RNZ Pacific's Dominic Godfrey has been following the meeting and speaks to Māni Dunlop in the Wellington studio.
