Professor Fergusson, at the beginning you talked about China's polar policy. You're thinking that they're going to do more transiting through the Russian Arctic side than through the Canadian Arctic portion of the Arctic Ocean, yet China's near-Arctic policy—it came out at the end of January—talks about the polar Silk Road, and specifically about coming through the Northwest Passage.
Is there a disconnect between what you envision they will use as trade routes versus what they are saying?
