(Reuters) - The U.S. presidential election in November will be a face-off between Democrat Barack Obama and Republican John McCain.

Following are some of McCain's and Obama's main positions on trade -- an issue that has become contentious during this election cycle.

REPUBLICAN SEN. JOHN MCCAIN OF ARIZONA

* Supports free trade pacts with Colombia, South Korea and Panama and negotiating a new free trade pact with the 27 nations of the European Union.

* Opposes changing NAFTA agreement.

* Favors opening new trade markets, but also advocates education and retraining for workers displaced by global trade.

* Has proposed partnerships with community colleges to retrain displaced workers and providing income assistance to those who find jobs that pay less.

DEMOCRATIC SEN. BARACK OBAMA OF ILLINOIS

* Urged renegotiating the North American Free Trade Agreement to strengthen provisions on labor and environment. Warned of opting out of the treaty if Canada and Mexico refuse.

* Opposed free trade pacts with Colombia and South Korea, but supported an agreement with Peru.

* Supports pressuring World Trade Organization to better enforce agreements and halt government subsidies to foreign exporters and imposing other nontariff barriers on U.S. exports.

* Wants to revamp fast-track trade negotiating authority to require pre-screening of potential U.S. free trade partners based on their labor and environmental standards and other factors.
