Disputes - international:
Antarctic Treaty freezes claims (see Antarctic Treaty Summary in
Government type entry); sections (some overlapping) claimed by
Argentina, Australia, Chile, France, NZ, Norway, and UK; the US and
most other states do not recognize the territorial claims of other
states and have made no claims themselves (the US and Russia reserve
the right to do so); no claims have been made in the sector between
90 degrees west and 150 degrees west; several states with land
claims in Antarctica have expressed their intention to submit data
to the UN Commission on the Limits of the Continental Shelf to
extend their continental shelf claims to adjoining undersea ridges
