US diplomats waged an overseas lobbying campaign to promote the use of GM crops, a new analysis of WikiLeaks documents reveals.

Campaign group Food and Water Watch reviewed more than 900 diplomatic cables from the WikiLeaks documents haul, which was released two years ago. 

The cables reveal a number of pro-GM public relations strategies aimed at extolling the benefits and safety of GM products, according to The Guardian. They also show that US officials opposed GM food labelling laws and rules blocking GM food imports.

“I’m especially concerned to see how much the cables have to do with changing laws and regulations of many of those countries,” said Wenonah Hauter, executive director of Food and Water Watch. “This corporate diplomacy was nearly twice as common as diplomatic efforts on food aid.”
