Chinese regulators conditionally approved the $130 billion merger between Dow Chemical (DOW) - Get Report and DuPont (DD) - Get Report , the world's two largest chemical producers. European regulators also conditionally approved the merger in March subject to divestments that satisfy antitrust concerns. 

China's conditions for approval include the divesting of DuPont's research and development department as well as any assets that relate to pesticides and herbicides used in rice, the Commerce Ministry said. 

The two companies are still awaiting approval in the U.S., Brazil, Australia and Canada.
