BRASILIA, Dec 9 (Reuters) - Brazilian Foreign Minister Celso Amorim warned on Tuesday that global trade talks would fail if members of the World Trade Organization tried to revise positions they had reached in July.
The WTO is considering whether to hold a ministerial-level meeting in Geneva in coming days to advance talks that collapsed in July over safeguards to protect domestic farmers from a flood of food imports.
But that meeting produced preliminary agreement in several areas, including an outline of possible tariff reductions on manufactured products.
"Any attempt to rebalance the July package will result in failure," Amorim said.
The United States wants Brazil, India and China to commit to taking part in deals eliminating tariffs in individual sectors such as chemicals but the big emerging countries say participation must be voluntary.
"Any attempt at this time to convert the basis of sectorial talks from something voluntary to obligatory ... we better not go to Geneva at all," Amorim said in Brasilia.
As a key farm goods exporter Brazil has played a key role in the talks, attempting to forge a common front of developing countries in the so-called G20 group.
An accord would require full consensus among the WTO's 153 members.
