The World Bank warned the trade negotiators that delivering a Doha deal that spurs development would not be "easy" as they might "well have to transcend the mercantilist mind-set". In its Global Economic Prospects Report (GEP), 2004 released here by the Bank's Lead Economist Mr Aaditya Mattoo and Senior Economist and Mr Dominique Van Der Mensbrugghe, the bank has urged all segments of the global community must keep their focus on potential gains, not only from "winning concessions" from foreign partners, but also on the gains from domestic reforms that "pay for" foreign concessions.
