(Interactive graphic) China has been steadily increasing its foreign investments outside of bonds in recent years. Between 2005 and 2010, it made more than $224 billion in overseas investments and also entered into engineering and construction contracts of more than $94 billion, according to data compiled by The Heritage Foundation, a conservative think tank in Washington, D.C. The group tracks China’s foreign nonbond investments and contracts worth more than $100 million. Before 2005, China had relatively few overseas investments outside of bonds, says Heritage’s Derek Scissors. But China’s investments are still dwarfed by the United States, he says.
