For the past decade, the Davos meeting has brought together big business, high finance and top politics to promote and celebrate the integration of the global economy. Whatever their business rivalries or political differences, the Davos delegates all agreed that the road to peace and prosperity lay through more international trade and investment – globalisation, in short.

But this year the forum has had to confront a new phenomenon – deglobalisation. The world that Davos Man created is slipping into reverse. International trade and investment is falling and protectionist barriers are on the rise. Economies are shrinking and unemployment is growing.

The symptoms of deglobalisation are all around us. Last week, it was reported that global air cargo traffic in December 2008 was down 22.6 per cent compared with December 2007. Abhisit Vejjajiva, prime minister of Thailand, told the forum that tourist receipts in his country had fallen by about 20 per cent year-on-year, in line with the general decline in international travel (and stripping out the effects of the temporary closure of Bangkok airport). In the US and Europe, governments are scrambling to bail out not just banks but also car companies. But, as the European Union has long acknowledged, “state aid” to national industrial champions is a form of protectionism.
