Biden's cancelled Asia trip raises concerns over US commitment to Pacific region.

US President Joe Biden cancelled his trip to Papua New Guinea, where he was supposed to sign a security pact with the country's Prime Minister James Marape. Instead, US Secretary of State Anthony Blinken will sign an agreement giving US forces access to PNG airfields and ports. The Pacific Islands are strategically placed and resource-rich, and both the US and China are vying for influence in the region. While Pacific Island leaders welcome the attention, they have their own priorities, including climate change.
