The comment from Sato Kilman, a former prime minister, comes after another call on West Papua by Vanuatu at the United Nations.
Speaking at the UN General Assembly, current prime minister Charlot Salwai called for an investigation into alleged killings and abuses of the indigenous people of Indonesia's Papua region.
Mr Kilman said the UN was the right place in which to raise concern on Papua.
But he questions whether Vanuatu takes the same stand on similar issues in other parts of the world.
