WASHINGTON, Dec 4 (Reuters) - President Barack Obama vowed on Saturday to work with Republicans and Democrats to pass a free-trade pact with South Korea that he said was a model for future agreements he would seek in Asia and around the world.
U.S. and South Korean negotiators struck a deal on Friday on the long-delayed pact, which was signed in 2007 but had not been ratified for three years because of U.S. auto and beef industry concerns.
The pact was an accomplishment for Obama, who faced an embarrassing setback when negotiators failed to settle their differences before he visited Seoul last month.
"The agreement we're announcing today includes several important improvements and achieves what I believe trade deals must do. It's a win-win for both our countries," he told reporters in Washington.
A day after the Labor Department reported U.S. unemployment unexpectedly hit a seven-month high of 9.8 percent in November, Obama said the pact would boost annual exports of automobiles, agricultural products and other goods and services by $11 billion and generate 70,000 additional jobs.
Obama said the agreement with South Korea showed the United States was ready to finalize more trade pacts -- business leaders wish two other long-delayed deals, with Panama and Colombia, would also get through Congress.
"I'm especially pleased that this agreement includes groundbreaking protections for workers' rights and for the environment. In this sense, it's an example of the kind of fair trade agreement that I'll continue to work for as president, in Asia and around the world," Obama said.
"This agreement also shows that the United States of America is determined to lead and compete in our global economy," he added.
He also said the agreement shows the strength of Washington's alliance with Seoul. Tensions in the region ratcheted up last month after North Korea attacked the small southern island of Yeonpyeong, killing four people.
BUSINESS SUPPORT, SOME DOUBTS
Business leaders and analysts said free trade could be one area of cooperation between Obama's Democratic administration and Republicans in Congress, who won a majority in the House of Representatives in the Nov. 2 elections, amid voter discontent over the sputtering economy and worries over the U.S. deficit.
Obama said he looked forward to working with Congress and leaders of both parties to approve the pact.
Both the U.S. House and Senate must approve the agreement, and Senate Republican Leader Mitch McConnell said he was prepared to work with Obama to win approval. A range of companies and industry groups have spoken out in support, including the United Auto Workers union and Ford Motor Co., which welcomed the changes made to address their concerns about market access provisions of the original deal.
House Majority Leader Steny Hoyer, a Maryland Democrat, also praised the deal.
But despite progress on the auto issues, Senate Finance Committee Chairman Max Baucus, a Montana Democrat, said he was "deeply disappointed" the deal did not address South Korea's remaining restriction on beef imports imposed in response to discovery of several cases of mad cow disease in the U.S. cattle herds a number of years ago.
Baucus, whose committee has jurisdiction over trade, said he would reserve judgment while continuing to work with the Obama administration.
Obama said the United States would continue to press for "full access for U.S. beef to the Korean market."
Obama has made increasing U.S. exports a focus of his strategy for generating jobs.
"(The Korea pact) will contribute significantly to achieving my goal of doubling U.S. exports over the next five years. In fact, it's estimated that today's deal alone will increase American economic output by more than our last nine free trade agreements combined," Obama said.
