The number of new anti-dumping investigations soared by nearly 40 per cent in the first six months of this year, the World Trade Organisation said on Monday, reflecting increased trade tensions as the credit crunch began to take its toll on the global economy.

Between January and June 16 WTO members started 85 new investigations compared with 61 in the first six months of 2007. China was the target of nearly half the probes, a jump of 75 per cent over the same period last year.
