Obama urges Bush back off South Korea trade deal

By Doug Palmer

WASHINGTON (Reuters) - Democratic presidential front-runner Barack Obama in a letter released on Friday warned of a major fight over a free trade agreement with South Korea if President George W. Bush sends it to the U.S. Congress.

"Instead of provoking unnecessary and potentially corrosive confrontation over this agreement, your administration could make a significant contribution toward reestablishing trust with Congress and restoring bipartisan cooperation on trade by withholding the agreement," Obama said.

Obama's Senate office released the letter, dated on Thursday, shortly after a White House event where Bush pushed for approval of free trade pacts with Colombia, Panama and South Korea before the end of this year.

The trade pact with South Korea, the United States' seventh largest trading partner, is by far the biggest the Bush administration has negotiated and also the largest U.S. deal since the North American Free Trade Agreement.

The U.S. International Trade Commission has estimated it would increase annual U.S. exports to South Korea by between $10 billion and $11 billion, and increase imports from the longtime Asian ally by between $6.4 billion and $6.9 billion.

The fate of all three pending agreements has been up in the air after the House of Representatives voted last month to indefinitely postpone action on the Colombia agreement.

Bush acknowledged the current political climate made it difficult to win approval of the trade deals, but said he had not "given up hope" that Congress would approve the Colombia agreement and then the two other trade deals.
