China is refusing to agree to make its aid spending in the Pacific more transparent and co-operate with other donor countries.
The Pacific Islands Forum leaders yesterday held talks with the leaders of observer countries and organisations - the largest delegations being from the US and China, wrestling for influence in the region.
Prime Minister John Key said the Chinese delegation had made it clear they did not want to be bound by the "Cairns Compact" - a Forum agreement for better co-ordination and information-sharing about aid programmes.
He said China had listened to the arguments about why including the Asian superpower in that co-operation would benefit the region.
"We will continue with the dialogue, but in the end every country has a sovereign right to determine how its aid should be spent."
