Daniel Hannan www.hannan.co.uk Conservative MEP for South East England WHAT IS THE POINT OF A TRADE DELEGATION WHEN YOU CAN’T SIGN A TRADE AGREEMENT? It’s nice to see David Cameron in China. Indeed, it would be a dereliction of his responsibility not to visit that vast and complex country. China grew at 6.6 per cent last year while the eurozone shrank. The world is tipping: its economic centre of gravity is running east across the Russian steppes at 90 miles a day. This need not be bad news for the West: a rising giant lifts others, with or without meaning to.
