Vanuatu, still reeling from two cyclones that struck within a week, says it hopes the United Nations General Assembly will next week adopt its push for greater priority to be given to the human rights impact of climate change.

The Pacific island nation's Minister of Climate Change, Ralph Regenvanu, said 119 governments have co-sponsored Vanuatu's resolution, which seeks legal clarity on the obligation of states to take climate change action, and draws attention to the vulnerability of small islands states hit by worsening storms and rising seas.

Vanuatu hopes more nations will sign-on before the general assembly debate begins on Wednesday, and it will be passed by consensus, he said.
