Make-or-break talks will be held in Geneva this week to rescue the troubled Doha international trade round, amid fears that a deepening rift between rich and poor countries will see the collapse of almost 10 years of negotiations. After months of stalemate, the World Trade Organisation has set a deadline for the leading players to cut a deal in the key area of industrial tariffs. Pascal Lamy, the WTO's director general, described the situation as 'grave' after seeing no signs of a breakthrough since the start of 2011.
