SYDNEY – Pacific island leaders will meet South Korea's President Yoon Suk-yeol in Seoul on Monday.
This will be their third summit in a week with a large economy as the region seeks stronger action on climate change as it becomes a focus of geopolitical power attention.
The Pacific islands span 40 million sq km of ocean between the United States and Asia.
Western allies have moved to boost their engagement in the region amid concerns over China's security ambitions for the strategic waters and economic leverage among the small island states.
Australia's Defence Minister Richard Marles will attend the first Korea-Pacific Islands Summit, his office said on Saturday, adding it would show cooperation between the 18 members of the Pacific Island Forum and South Korea for a secure region.
“Australia welcomes Korea's interest in deepening ties with the Pacific, and looks forward to building on our foundation of shared values to promote our mutual interest in a prosperous and resilient Pacific,” he said in a statement.
South Korea is Australia's third-largest export market, with trade dominated by exports of gas and coal.
Mr Marles will also hold a bilateral meeting with Korean Minister of National Defence Lee Jong-sup.
Australia and New Zealand are the largest members of the Pacific forum, a bloc of mostly small island countries at risk from rising sea levels caused by climate change and reliant on aid from development partners.
India's Prime Minister Narendra Modi pledged more trade and development assistance in a summit with a dozen Pacific island leaders in Papua New Guinea (PNG) on Monday.
The United States Secretary of State Antony Blinken signed a defence agreement with PNG after a Pacific summit there on the same day.
The back-to-back meetings with major economies were a “massive boost for recognition of our priorities”, said Pacific Islands Forum Secretary General Henry Puna in a statement.
The island states, which are seeking greater funding for climate change mitigation, have taken a collective approach to dealing with major powers.
“Forum Leaders see this as vital to addressing the challenges facing the Blue Planet, to planning and owning our development agenda, and to deepened climate resilience,” Mr Puna said.
