China's wealth fund has lifted the veil on its U. S. securities holdings, revealing more than $9.6 billion of holdings in about 60 U. S. companies.

China Investment Corp. disclosed a $713.8 million position in Wall Street investment firm BlackRock and a $498 million position in two types of shares in the Brazilian metals giant Vale.

But CIC, which has $300 billion in assets worldwide, appears to be mostly taking modest positions without seeking management control. The biggest investments listed were CIC's well-known $1.7 billion stake in Morgan Stanley, and its $3.5 billion stake in Vancouver-based mining company Teck Resources.

CIC paid $3 billion for a 10 percent stake in Blackstone in 2007 and bought more shares in 2008. Canadian miner Teck Resources Ltd held the biggest holding listed in the SEC filing, worth $3.54 billion.

Lou Jiwei, the chairman of CIC, said the fund would manage more of its investments in developed markets internally and steadily accelerate its overseas investments.

CIC has been investing rigorously in resources and commodities since 2009, as there is plenty of room for price gains in the sectors. CIC needs to take steps against the growing problem of inflation as the world economy picks up. CIC's policy aims to operate the fund as a financial investor seeking to maximize its returns and not control the companies in which it invests.
