“China National Chemical Corporation (ChemChina) and Syngenta today announced that the companies have received clearance on their proposed transaction from the Committee on Foreign Investment in the United States (CFIUS),” a joint statement released by Syngenta said.

“In addition to CFIUS clearance, the closing of the transaction is subject to anti-trust review by numerous regulators around the world and other customary closing conditions. Both companies are working closely with the regulatory agencies involved and discussions remain constructive.

“The proposed transaction is expected to close by the end of the year.”
