BEIJING, Nov 6 (Reuters) - Chinese supply chain operator and property developer Xiamen C&D 600153.SS said on Thursday it had signed contracts totalling over $5.2 billion with seven agribusinesses and trading houses including Cargill and Louis Dreyfus Company in Shanghai.

The contracts signed covered soybeans, corn and cotton among other goods, the Xiamen-based company said in statements released on its Chinese social media account.

Xiamen C&D's deal with Cargill, a U.S. firm, would supply the Chinese company's animal feed and food processing businesses, according to one of the statements.

It was not immediately clear if the Cargill deal touches on soybeans, a highly watched commodity after Washington said China would resume purchases of U.S. soybeans as part of a trade truce reached last month.

The Chinese firm's $2.5 billion deal with agricultural commodity merchant Louis Dreyfus Company would help establish a stable global agricultural supply network, it said in a statement published on Wednesday.

Xiamen C&D's other contracts were signed with Swiss-based Syngenta and U.S.-based CHS CHSCP.O, as well as Olam OLAG.SI, BTG Pactual and Cutrale.
