Hu Xiaoyi, vice-minister of human resources and social security, said at a national conference on social insurance funding that 304 million urban Chinese were covered by the pension system, 50.9 percent higher than the number registered in 2007.

Gross revenues for social insurance funds totaled 2.85 trillion yuan ($457.45 billion) and gross expenditures reached 2.21 trillion yuan in 2012, 2.63 times and 2.8 times that of five years ago, respectively, the ministry said.
