GENEVA (AFP) -- Members of the World Trade Organization (WTO) met Friday to assess where to take tortured negotiations amid recriminations after the collapse of talks between four key players in Germany.

WTO Director General Pascal Lamy was to address the 150-strong Trade Negotiations Committee in Geneva in a bid to assuage concern that the failure of talks in Potsdam could point to the end of the road for the global trading round. The talks between the so-called "G4" -- the European Union, the United States, Brazil, and India -- broke down on Thursday. All parties now agree the focus will move to Geneva and multilateral negotiations. Three of the four main players from the G4 talks traveled Friday to WTO headquarters in the Swiss city to meet with Lamy and other delegations -- and to trade accusations of who was responsible for the Potsdam collapse. Brazil's top trade official and Foreign Minister, Celso Amorim, told reporters that the G4 was "dead," but the same should not be said for the wider Doha Round. Amorim blamed the EU and U.S. for the collapse, saying the two developed powers had arrived at Potsdam with their minds already made up on how much they were prepared to offer, and what they expected from the other two parties. "What they agreed, they considered to be the agreement," he said. This was denied by U.S. officials, with Agriculture Secretary Mike Johanns telling reporters that there was no pre-summit stitch-up between Washington and Brussels. "Nobody went to Potsdam with convergence with another country. To suggest otherwise isn't fair to the process," he said. U.S. trade representative Susan Schwab contrasted the flexibility of Washington's position with what she termed the "extremely rigid positions" of Brazil and India on a range of issues including agriculture, manufactured goods, and non-agricultural market access. "The United States came prepared to deal. The U.S. came prepared to stretch, prepared to do our share and then some to help convergence happen," Schwab said. However, she described the meeting in Potsdam as "less of a negotiation and unfortunately more of an auction, with the auctioneers saying 'Put more on the table, put more on the table, put more on the table.'" She said she liked and respected her G4 negotiating partners, but "some of us seemed to take the process more seriously than others, and I'm not sure why." Nevertheless, "we have not by any means given up on the Doha Round... for now we go away disappointed, but not prepared to give up," Schwab said. These sentiments at least were echoed by the Brazilian minister, who said: "I don't think that the Doha Round is dead, even that it is agonizing." It is "difficult but not impossible" for all 150 members of the WTO to arrive at a comprehensive global trade deal, Amorim added. An agreement between the G4, whose members comprise both developed and developing economies, had been seen as crucial for the success of any global trade deal. But Lamy has always stressed that any deal can be brokered only through inclusive multilateral discussions between all WTO members, warning before the Potsdam meeting that "there is no such thing as a special G4 entry key." The meeting of the four key players had in any case sparked the ire of other developing countries at the WTO, who argued that Brazil and India alone were not capable of representing all their interests. Jamaica's ambassador on behalf of the G90 Plus group said on Thursday that the two states alone could not negotiate on everyone's behalf and that other developing economies felt out of the loop
