China Cinda Asset Management Co, one of four State-owned managers of soured loans, increased its distressed-asset holdings 80 percent last year and expects buying opportunities to expand as the nation's economy slows.

China's largest so-called bad bank held 206.8 billion yuan ($33.3 billion) of distressed debts in 2014 from 114.8 billion yuan the previous year, according to financial results filed to the Hong Kong Stock Exchange on Friday. Cinda posted a 32 percent increase in net income to 11.9 billion yuan.

"Various hidden risks in the economic and financial systems will become apparent" as China's growth cools, China Cinda said in the statement. Cinda expects more opportunities from rising nonperforming loans and liquidity problems faced by some industrial enterprises, it said.
