57.     Treaties establishing territorial and analogous regimes.

Succession of states does not as such affect a boundary established by a treaty or rights and obligations established by a treaty and relating to the regime of a boundary1. The same is the case for various other territorial regimes2, as well as for fluvial3, lacustrine, and maritime regimes. If in force, the treaty in question is opposable to a successor state4.
