ChemChina / Syngenta
Simpson Thacher & Bartlett, Davis Polk & Wardwell, Clifford Chance and two Swiss firms have taken the lead on the largest outbound M&A deal by a Chinese company to date.

State-owned China National Chemical Corp., better known as ChemChina, said that it will acquire Swiss agrochemical giant Syngenta AG for $43 billion. The deal, which has its roots in China’s desire to secure a sustainable food supply for its surging population, comes after nearly a year of negotiations between the companies.
