Key World Trade Organisation (WTO) members have admitted they will not be able to agree a framework for a new trade deal at upcoming talks in China. But the five members did decide on a plan to conclude the current round of trade talks by the end of 2006. World leaders are seeking a breakthrough in the WTO's so-called Doha round of talks, which began in 2001 and aim to set out a system of trade rules that are fairer to developing countries.
