Thank you very much.
Mr. O'Rourke, for two years running, we've seen Chinese coast guard vessels operating in the Arctic. This year, the new class 1 icebreaker Xue Long 2 was shadowed by the Canadian Coast Guard from Japan to the Bering Sea.
Exploring that within the framework of NORAD, can you tell us why they were tasked with shadowing that vessel from Japan to the Bering Sea to the Arctic?
