Hu Xiaoyi, vice minister of the Ministry of Human Resources and Social Security, said that the national social security fund will be invested in more than one channels to form an invesement portfolio in a bid to hedge against inflation, China Securities Journal reported Friday.

"The designing of the investment methods entails a comprehensive and complicated process. The appropriate method should be in a portfolio format instead of investing in a single channel," Hu said. He did not state the exact time that the fund would enter the security market.

In a meeting held on Thursday, Hu revealed that China will continue to enlarge all kinds of social security coverage, with the number of citizens covered by basic pension insurance in rural and urban areas to reach 305 million.
