Chinese investors evaded government controls to move more than $600 billion U.S. out of the country last year and the outflow is increasing, fueling economic and political risks as communist leaders prepare for a handover of power, a Washington-based monitoring group says.
The study by Global Financial Integrity gives backing to anecdotal signs of huge, unreported movements of Chinese money out of the country.
Experts say the outflows are driven by public frustration with a banking system that subsidizes state companies at the expense of savers and by businesses profiting from loopholes in the government's pervasive economic controls.
Chinese companies are widely believed to move money abroad both to invest and to "round trip" back into the country disguised as foreign investment to win tax breaks and other incentives.
Chinese families move money abroad to gain a better return than they can from state banks that pay low deposit rates.
Last year's outflow was part of a $3.8-trillion U.S. flood of capital that left China over 11 years, Global Financial Integrity said. It said the amount rose from $172.6 billion U.S. in 2000 to $602.9 billion U.S. in 2011.
The group said it was unclear how much of the money came from corruption or other crimes but it said the illicit outflow could aggravate economic and political strains by aiding tax evasion and widening China's sensitive wealth gap.
The study "raises serious questions about the stability of the Chinese economy," the group said in a statement.
Some commentators have suggested the outflows reflect a loss of faith by China's financial elite in the communist government but others say much of the money is sent back into the country disguised as foreign investment.
Some of the outflow also might be the proceeds of bribe-taking and other government corruption. Stories of officials who move their families and ill-gotten assets abroad are so common that Chinese Internet users have coined a name for them — "naked officials."
Public concern about chronic corruption and China's slowing economy are political risks for the ruling Communist Party as it prepares for a once-a-decade handover of power to younger leaders.
