President Roh Moo-hyun said Thursday South Korea won't sign a free trade agreement with the United States if it perceives it might get the short end of the bargain, AP reported. «I would not engage in a losing business,» Roh said in a meeting with citizens, broadcast live via nation's major Internet portals, adding that South Korea will reach an accord with Washington that is acceptable to his country. Roh, however, stressed the importance of free trade accords to South Korea's economy, which depends on exports for most of its economic growth, saying such agreements symbolize South Korea's opening up to the global economy.
