The National Council for Social Security Fund, China's largest limited partner, has only invested 2.2 percent of its money into the venture capital and private equity sectors, and there is ample room for growth, said Wang Zhongmin, vice-chairman of the SSF, on Wednesday.

"Under the rules, up to 10 percent of the social security fund can be used for venture capital and private equity investment, and the ratio at the end of 2011 was only 2.2 percent," Wang said.

"While the securities market is volatile, the primary market is full of investment opportunities for us to seek and seize."
