US President George W. Bush defended the North American Free Trade Agreement on Tuesday, saying "now is not the time to renegotiate NAFTA or walk away from NAFTA."

The three-nation trade pact has come under fire from US workers' unions and on the presidential campaign trail, with Democratic contenders Hillary Clinton and Barack Obama warning they would renegotiate it if elected.Agence France Presse
