China's banking regulator has recently asked lenders to assess their credit-risk exposure to companies active in overseas acquisitions, sources close to the regulator told online news service Caixin, as the country continues to curb a shopping spree that led to a record capital exodus last year. The China Banking Regulatory Commission said the risk assessment includes Anbang Insurance Group Co, Fosun Group, Wanda Group, and the unit of Sino-Europe Sports Investment Management Changxing Co that recently acquired Italy's AC Milan soccer team, the sources said.
