The EU's trade chief, Peter Mandelson, blamed the failure on the United States, saying Washington was "unwilling to accept" the flexibility shown by others.

The meeting had been called by WTO Director-General Pascal Lamy with ministers from Australia, Brazil, the 25-nation European Union, India, Japan, and the United States to try to reenergize the talks.
This group, known as the G6, accounts for some three-quarters of world trade.
