One-third of the China CFOs asked identified financial market risks, including interest rate risk, counterparty risk and liquidity risk, as their primary concern for 2014. Over 40 percent of China's CFOs cited liquidity risk as a concern, trailing only South Korea (49 percent) and Taiwan (43 percent).
