Prime Minister Stephen Harper said Tuesday he is ``delighted'' the administration of U.S. President Barack Obama has closed the door to reopening the North American Free Trade Agreement.
U.S. Trade Representative Ron Kirk told reporters in a conference call on Monday that it is not necessary to renegotiate NAFTA to honour Obama's campaign promise to add stronger labour and environmental provisions.
``The president has said we will look at all options,''Kirk said. ``But I think they can be addressed without having to reopen the agreement.''
