China's sovereign wealth fund has bought a stake in a Hong Kong-based commodities trading firm.
China Investment Corp, the country's $200bn (£123bn) fund, took a 15% stake in Noble Group in return for $850m.
The deal comes after China recently signed a pact with another commodity trader, Glencore, in an attempt to increase its influence in the sector.
China's rapid economic growth has made it one of the world's largest consumer of raw materials such as oil and steel.
Noble, whose shares are listed in Singapore, is one of the few publicly-listed commodity trading houses.
China's fund bought its shares at an 8% discount to Noble's last traded share price of 2.30 Singapore dollars.
Noble has investments in Australian coal, soybean crushing plants and sugar and ethanol mills in Brazil, among others.
In July, China Investment Corp paid $1.5bn for a 17% stake in Canadian miner Teck Resources Ltd.
"A lot of sovereign wealth funds or state-linked firms are increasingly showing interest in resources, so this is in line with the trend," said OCBC Securities analyst Lee Wen Ching. "Noble provides access to a diversified portfolio."
Sovereign wealth funds are the investment funds established by governments in Asia and the Middle East mainly, who have large surpluses of money which they wish to invest abroad.
Abu Dhabi has the largest fund, at $800bn, while Norway's is $400bn and Singapore has a $330bn sovereign fund.
China's fund was established in September 2007.
