The China Investment Corporation (CIC), the country's sovereign wealth fund, said on Tuesday it has made a return of 11.7 percent on its global investment portfolio in 2010.

The rate was unchanged from that of 2009, reversing losses in 2008 when the rate was a negative 2.1 percent, CIC said in its third annual report.

The fund's average investment return since its founding in 2007 was 6.4 percent, it said.

The CIC was founded in September 2007 to mitigate risks in China's huge foreign exchange reserves.
