China’s sovereign wealth fund is set to post its best yearly gain in 2009 after stepping up investments in commodities to ride a rebound in global markets.

China Investment Corp. is likely to report a return on its global portfolio “well over 10 percent” in its upcoming annual statement, said Rachel Ziemba, London-based senior analyst at Roubini Global Economics. The $300 billion fund had a 2.1 percent loss on its global assets in 2008, after chalking up a 0.2 percent return in its starting year of 2007 when the value of a $3 billion investment in Blackstone Group LP plunged.

Chairman Lou Jiwei pumped nearly $10 billion into commodity-related companies such as Canada’s Teck Resources Ltd. in the second half to benefit from the global economic recovery. That compared with $4.8 billion in new investments across all industries for the entire 2008.

“2009 results should be good because commodities staged a strong rally,” said Francis Lun, general manager at Fulbright Securities Ltd. in Hong Kong. “CIC was very timid, which actually helped it to avoid the financial tsunami” in 2008.
