Canada and Russia agreed Thursday to expand economic cooperation in areas of agriculture, fisheries, nuclear power and trade financing, officials said. The pact came at the close of a working visit by Russian Prime Minister Viktor Zubkov and four Russian cabinet ministers. The deal also followed a 2006 accord by Canada`s Prime Minister Stephen Harper and Russian President Vladimir Putin, as well as a joint business summit held in Ottawa last March. Over the four years between 2002 and 2006, bilateral trade has jumped from 620 million dollars to 2.3 billion, officials said. This deal was to increase promotion of bilateral trade and investment, foster greater cooperation in the peaceful uses of nuclear energy, create joint agricultural projects and collaborate on fisheries, particularly in the Northwest Atlantic and North Pacific. Further, "it was agreed that Russia`s integration into the world economy would be enhanced through membership in the World Trade Organization and the Organization for Economic Co-operation and Development," officials said in a statement. Russia, which began accession negotiations in 1993, is the last remaining major economy not to be part of the WTO, and is not included in the OECD. The talks have been complicated by long-standing political grievances between Russia and EU member Poland which have spilled over into trade issues. Membership requires unanimity of all WTO states.
