ChemChina extends $43 bln Syngenta buyout offer to Jan 5

ZURICH, Nov 1 (Reuters) - State-owned China National Chemical Corp (ChemChina) on Tuesday said it has extended its $43 billion cash offer for Swiss agrichemicals group Syngenta AG to Jan. 5 while it works to gain regulatory approval for the deal.

"ChemChina is aiming to obtain the remaining outstanding regulatory approvals in the first quarter of 2017," the firm said in a statement.

European Union anti-trust regulators on Friday opened an in-depth investigation into the deal, China's biggest-ever foreign acquisition.
