Ask Greenland Authorities... They tried doing so during oil drilling off the west coast, to keep Greenpeace helicopters away.... Greenpeace dragged it through court (or almost, a complaint to the CAA was enough), and the CAA stepped in and the area was removed. It has to be said the CAA wasn't involved in the decision beforehand, so they were not to blame.
Eventhough you have class A airspace etc. over international waters, you still see the military of particular nations give a crap and fly VFR through it.
