During his speech in New York, Charlot Salwai lamented how some Pacific territories are yet to break the shackles of colonialism.
Mr Salwai cited France's territories of New Caledonia and French Polynesia, as well as Indonesian-ruled West Papua.
He called on the administering powers to respect UN processes and ensure people in these territories can have their self-determination views heard.
Mr Salwai called for use of the UN system to find solutions to violations of West Papuans' human rights.
