The West Papua National Coalition for Liberation says its decolonisation aspirations are focussed on action at the United Nations.
The Coalition is one of the key groups within the United Liberation Movement for West Papua, which is pushing for internationally-facilitated negotiation with Indonesia over Papua's political status.
Various Papuan civil society, church and customary leaders met with Indonesia's president Joko Widodo last month about establishing dialogue over problems in Papua.
However self-determination is not expected to be on the agenda in the dialogue, in which the Liberation Movement is not involved.
The Coalition's chairman Andy Ayamiseba says the Movement rejects direct dialogue with Jakarta because it considers Indonesia an illegal occupier in Papua.
