The China Project, a New York-based, China-focused news, information and business services platform, recently reported on newly passed state legislation in Arkansas that has resulted in ordering Chinese state-owned company Syngenta, a seed and pesticide giant, to sell its land holdings in the state. In addition to Arkansas, other states including Florida, Louisiana, Montana, North Dakota and Ohio have since passed legislation that restricts some land ownership for Chinese citizens or companies, according to The China Project. Ronald Cheng, a Pillsbury partner who focuses on complex litigation in China, said the state provisions are likely to come under legal objection from affected companies.
