Which country is planning to relocate some inhabitants from the Pacific Island of Tuvalu due to rising sea levels?

New Zealand is planning to relocate some inhabitants from the Pacific Island of Tuvalu in response to the urgent challenges posed by rising sea levels. This decision stems from Tuvalu's vulnerability to climate change, particularly how rising sea levels threaten its land, infrastructure, and ultimately the safety and livelihood of its people. New Zealand has established policies focused on providing support and resettlement options for those affected by climate change, reflecting a proactive approach to environmental issues impacting neighboring Pacific Island nations.

The other countries listed may have their own policies regarding climate change and aid but are not directly involved in resettling Tuvalu's inhabitants as New Zealand is. This highlights the unique relationship and responsibilities that New Zealand has taken on in addressing the challenges faced by Tuvalu.
