Cargill Inc’s lawsuit against Syngenta AG over rejections of genetically modified U.S. corn by China may be just the start of legal challenges against global seed makers over trade with one of the world’s biggest markets.

Trading giant Cargill said in court documents on Friday that it had lost more than $90 million because Syngenta sold Agrisure Viptera corn, known as MIR 162, to U.S. farmers without first obtaining import approval from China, which has turned away boatloads of U.S. crops containing the variety over the past year.
