Vanuatu's West Papua Unification Committee has dismissed the credentials of a man claiming to be a West Papuan envoy.
Paul Peter Masta claims to be the Federal Republic of West Papua's Ambassador to Papua New Guinea.
He has provoked consternation from West Papua leaders based in Vanuatu for denouncing the outcome of the West Papua Forum in Port Vila last year.
This forum, organised by the committee, elected the United Liberation Movement of West Papua which subsequently submitted a formal application for West Papua to join the Melanesian Spearhead Group.
But Mr Masta says the Federal Republic of West Papua has already submitted its own application to become a member of MSG with endorsement from the Indonesian President, Joko Widodo.
However, the committee chairperson, Pastor Allan Nafuki says the MSG received only one application and it was from the West Papua umbrella body established last December.
Pastor Nafuki says the MSG won't consider any other application and he is aware that Mr Masta is working for Indonesia in its last resort to confuse the people of West Papua and destabilise their organisation.
