Mexican authorities board the Arctic Surise and speak with Greenpeace campaigners. Greenpeace activists stop first shipment of genetically engineered maize entering Mexico by chaining themselves to the anchor chain of cargo container Ikan Altemira carrying a 40,000 tonne shipment of US GE contaminated maize destined for the port of Veracruz. The action takes place during the WTO meeting in Cancun.
