‘insular pacific state’ or ‘island pacific state’ or ‘island state of the Pacific Ocean’

The original translation is correct, but might be met with a little confusion.
‘Pacific’ is sometimes used as a simple adjective, meaning peaceful, and so putting in full avoids confusion. Insular also means isolated, so writing as ‘island’ avoids this confusion. Land locked states in the middle of Asia can also be described as insular, though not islands. I’m just pointing out that ‘insular pacific state’ can also mean ‘isolated peaceful state’.
