(VOVworld)- WTO director-general Roberto Azevedo has hailed the decision made at the Bali WTO Trade Ministers’ Meeting a historic global deal to bring most benefit to developing countries. He said at the closing ceremony of the meeting in Indonesia on Saturday that global citizens, especially the poor and most vulnerable groups, will benefit from the package, which may inflate world income by 1 trillion US dollars and create 21 million jobs, most of them in the developing world.
