A key figure is snubbing a government invitation to go to China for the signing of a free trade agreement.
Peter Dunne's United Future party backs the agreement but the Revenue Minister says he is boycotting the trip in protest at China's Crackdown in Tibet.
Dunne says he was invited to accompany Prime Minister Helen Clark at the ceremony next month, but has declined the offer.
He says to travel to Beijing to witness the signing while the events are taking place in Tibet would be totally inappropriate.
