The number

2.2 Trillion yuan

Unfunded liabilities in the individual accounts of China's pension system exceeded 2.2 trillion yuan ($348 billion) in 2011, about 500 billion yuan more than that in 2010, Zheng Bingwen, director of the Global Pension Fund Research Center under the Chinese Academy of Social Sciences, told the Beijing-based Economic Information Daily. Chinese employees had paid 2.5 trillion yuan into their pension accounts by 2011, but only about 270 billion yuan was payable, he said.
