Chongqing turning into trade powerhouse

Chongqing, a municipality in southwestern China, might have seemed like an unlikely place for a coffee trade center before the city announced the establishment of the Chongqing Coffee Exchange in June.

But now it hopes to become the world's third-largest coffee futures market, after New York and London.

Its big ambitions ride on an intercontinental railway connecting Chongqing and Germany, the brainchild of local government that began operating in 2011.
