The world's greatest developed and developing powers are set to call for an immediate restart of the stalled Doha round of World Trade Organization talks with a view to reaching a deal in 2010, diplomats said Thursday, according to dpa. A draft declaration prepared for a summit of the Major Economies Forum - the world's 16 most powerful states - in the Italian city of L'Aquila calls for trade ministers to resume Doha talks in the US city of Pittsburgh ahead of a G20 meeting in late September, diplomatic sources told the German Press Agency dpa.
