WTO negotiators reached agreement early Sunday on a sweeping trade deal dismantling barriers to trade in agriculture, manufacturing and services, Indian Trade Minister Kamal Nath said. Delegates met overnight and managed to overcome differences on a draft text setting an end date for farm export subsidies, a major sticking point. A final agreement on an exact date was expected later in the day, Nath said. "We'll have a definite date," he said. "We have a deal." Nath said that ending agricultural export subsidies - or funds that governments pay producers to promote agricultural exports - by 2013 would be acceptable to India, one of the leading developing nations and a key player in the rules-setting World Trade Organization. But Nath said the WTO's 149 members had yet to agree what that date would be.
