In late November the European Commission released a discussion paper called "The European Union and the Arctic Region." The Commission news release describes the paper as a first step towards an E.U. Arctic policy.
Among other things, the paper recommends that, "...Member States and the Community should defend the principle of freedom of navigation and the right of innocent passage in the newly opened routes and areas."
Canada considers the straits of the Northwest Passage to be her own internal waters. Some Canadians think the reference to "freedom of navigation" suggests a threat to this Canadian position. Mark Collins has a helpful set of links to the Canadian debate over at The Torch:The Arctic and the Northwest Passage: The Euro threat.
