Chinese companies and banks were once seen as bold and fearless as they invested in countries Western investors deemed too risky. But this may now be changing. In 2007, when two Chinese state-owned companies struck a deal with the Congolese government to build the biggest mine the country had ever seen, all involved were riding high. In a mega-deal originally worth some $9 billion, Sinohydro and the China Railway Engineering Corporation (CREC) would gain access to 6.8 million metric tons of copper, the future profits of which were to underwrite the prior building of hospitals, roads and other infrastructure.
