Germany believes China, India and the US should be forced to adopt higher environmental and health standards if they want to export food products to the European Union, says Horst Seehofer, Germany’s farm minister.

His comments echo calls by Paris for new EU barriers to free trade in response to rising global demand for food. Michel Barnier, France’s farm minister, last month called for curbs on “free-market liberalism”, a view reflected by Mr Seehofer: “We need more market liberalisation, but under fair conditions.”
