Papuan independence activists have welcomed Vanuatu's strong support for their cause at the United Nations, and have urged other Pacific countries to add their voice to the campaign.

Last week, Vanuatu's deputy prime minister, Serge Vohor, urged the United Nations to place the Indonesian province of Papua back on the list of regions awaiting decolonisation, as a first step towards independence.

Mr Vohor also announced Papuan independence activists would open up a new representative office in Port Vila, following a traditional ceremony cementing cultural ties between Papuans and the people of Vanuatu.

Rex Rumakiek, from the Australian-based Australia West Papua Association, says while Vanuatu is the only Pacific country to openly support their claim, other leaders are campaigning behind the scenes to support their cause.
