Interesting ….UK showed decent growth in bilateral economic trade with China in 2012. UK showed 15.5% growth in exports to China compared with zero or negative growth from the majority of European countries.
Two things helping here, China was venue of last Olympics and UK this year I’m sure helped strengthen relations, co-operation and opportunities for networking and deal making. Also London is arguably the capital of global FX trading due to its position right bang in the middle of time zones of the major financial centres ( US, Europe & Asia). China is moving to allow London as a location for offshore dealing in the Yuan which would be the first in the world not in China I believe. Only stands to reason then that trade between the two would and should increase.
