The U.S. Commitee on Foreign investment has approved the China National Chemical Corp. (ChemChina) purchase of Syngenta for $43 billion, the companies said Monday. Syngenta stock soared nearly 12 percent on the news.

Syngenta, based in Basel, Switzerland, has North American headquarters in Greensboro and multiple facilities in Research Triangle Park.

Syngenta pointed out that the deal is still subject to antitrust review by various regulators globally and other closing conditions.

In a statement, Syngenta said, “Both companies are working closely with the regulatory agencies involved and discussions remain constructive.”

Syngenta (SYNN.S) declined acquisition offers last year from Monsanto, another agribusiness with a major Triangle presence.

The deal would be the largest overseas acquisition by a Chinese company ever.
