FACTBOX: Trade issues in the U.S. presidential race

(Reuters) - The U.S. presidential election on November 4 will be a contest between Democrat Barack Obama and Republican John McCain.

Following are some of McCain and Obama's main positions on trade -- a contentious issue in this election.

MCCAIN

* Free Trade Agreements. Supports congressional approval of deals the Bush administration has negotiated with Colombia, South Korea and Panama and wants to negotiate a new free trade pact with the 27 nations of the European Union.

* North American Free Trade Agreement. Says the United States has benefited from the 14-year-old pact and opposes any "unilateral" U.S. effort to force changes in the agreement.

* World Trade Talks. Favors completion of the Doha round of world trade talks that were launched in 2001 with the goal of helping developing countries prosper through trade.

* Fast Track. Wants renewal of "fast track" negotiating authority that allows the White House to negotiate trade deals that Congress must approve or reject without changes

* Trade Enforcement. Believes negotiation of trade agreements must be accompanied by effective enforcement to make sure other countries live by the rules.

* Retraining. Wants to overhaul unemployment insurance to make it a program for retraining, relocating and assisting workers who have lost their jobs.

* Immigration. Promises action to secure U.S. borders, followed by a temporary worker program to meet U.S. labor needs and deal with the many undocumented workers already in the United States. Wants market forces to play a greater role in determining the number of low-skilled and highly skilled foreigners who can work in the United States.

OBAMA

* North American Free Trade Agreement. Wants to work with the leaders of Canada and Mexico to amend the pact to strengthen labor and environmental protections.

* U.S.-Colombia Free Trade Agreement. Believes Colombia must do more to reduce murders and other violence against trade unionists before Congress votes on the pact.

* U.S.-Korea Free Trade Agreement. Wants to renegotiate the pact to strengthen "badly flawed" agricultural and manufacturing provisions that he says fail to adequately open South Korea's market to U.S. exports.

* World Trade Talks. Says would work to complete a Doha agreement that would increase U.S. exports, support good jobs in America, strengthen the rules-based multilateral system, and advance development of the world's poorest countries.

* Trade Enforcement. Believes the United States needs to be more aggressive in filing cases against the World Trade Organization against countries that violate global trade rules to keep out U.S. goods.
