Call it the free trade follies. South Korean opposition politicians last week used a sledgehammer to try and force their way into a barricaded committee room to stop the ruling party from introducing debate on a tariff-slashing free trade agreement with the United States, according to AP. Fire extinguishers were used amid the melee _ it's not entirely clear by whom _ that threw South Korea's National Assembly into chaos. The brouhaha highlights the emotional intensity such pacts can trigger _ as well as this one's murky outlook. The South Korea-U.S. Free Trade Agreement has languished in political limbo since being signed nearly 18 months ago. It still needs approval from legislatures in both countries, but two major developments since then have raised questions about its passage: Major political changes in both South Korea and the United States and the global financial crisis. Conservative South Korean President Lee Myung-bak, who took office in February, is a firm supporter of the deal, negotiated and signed by the previous liberal Roh Moo-hyun administration. Lee's Grand National Party wants South Korea to ratify the pact first _ as early as by the end of this year _ potentially making it harder for the incoming U.S. administration of President-elect Barack Obama, seen as taking a harder line on free trade, to call for a renegotiation of the free trade agreement. Fears of such a scenario intensified as a result of the final presidential debate in October, when Obama singled out South Korea by noting a wide imbalance in auto trade between the two nations _ in particular the far smaller number of U.S. cars entering South Korea. «That is not free trade,» he said in the debate. «We've got to have a president who is going to be advocating on behalf of American businesses and American workers and I make no apology for that.» South Korean automakers including Hyundai Motor Co. sold 772,482 vehicles in the United States in 2007, while Detroit sold 6,235 in South Korea, according to statistics compiled by South Korean auto industry groups. Members of Roh's former party, now in opposition under a new name, the Democratic Party, say they still favor the deal _ but want to ensure measures are in place to help farmers and others seen as vulnerable to more U.S. imports. They warn against being too hasty in ratifying the agreement. So on Dec. 18, when the ruling GNP introduced legislation to a National Assembly trade committee without the Democrats, the opposition politicians used a sledgehammer and other construction tools to tear open the committee room's wooden doors, only to find GNP lawmakers had set up barricades of furniture inside. The attempt to storm the room failed, and the GNP introduced the bill _ a move the Democratic Party called illegal.
