When Mr. Bachand was asking about no man's land in the middle of the Arctic, that's like the land in the middle of the Pacific Ocean or the Atlantic Ocean. It simply falls under UNCLOS for anyone in the world to use.
The part of UNCLOS that talks about the 350 miles as the limit, that part is a bit confusing. Are there not different interpretations to which the 350 miles may not apply to some extent, and it could go on even farther than that?
