Responding to concerns by U.S. lawmakers, Syngenta says the takeover by ChemChina of Syngenta poses no food or national security issues. Ag Professional reports Syngenta made the response following the concerns in a letter by four senators requesting the Committee on Foreign Investment review the $43 billion deal’s potential impact on the U.S. food system. The senators feared that increased foreign control over important parts of US food production could create threats to domestic food security. A Syngenta spokesperson responded by saying while the company would welcome a full review, it believes the proposed takeover would not pose any security or food safety issues. The company says the takeover would be beneficial to farmers and customers in the United States. Syngenta generates 27 percent of its sales in North America.
