Clifford Chance has advised Chinese state-owned food giant COFCO Corp. on its acquisition of a controlling stake in Dutch grain trader Nidera.

Under the agreement, COFCO will acquire 51 percent of Rotterdam-based Nidera. The financial details of the transaction were not disclosed, but media reports citing sources familiar with the deal have said it values Nidera at $4 billion. The Dutch company has annual revenues of over $17 billion, COFCO said in a press release.

The deal is widely seen as part of an effort by the Chinese government to secure new supplies of food for the world’s largest population. Nidera trades grains, oilseeds, vegetable oils and bioenergy products from the Americas, Eastern and Central Europe and Australia.

Beijing partner Terence Foo and Amsterdam partner David Griston led the team at Clifford Chance advising COFCO.

Shearman & Sterling Hong Kong partners Paul Strecker, Peter Chen and Paloma Wang and New York partner Beau Buffier acted as Hong Kong and U.S. counsel to Nidera. NautaDutilh advised Nidera on Dutch law.*
