Access to and from the sea for landlocked states has been a long-standing issue in the law of the sea. Such issue is also addressed by the Convention on the Legal Status of the Caspian Sea (or Aktau Convention), which foresees a right of free access to other seas for landlocked State Parties—Azerbaijan, Kazakhstan, and Turkmenistan—through the Russian Federation. At the same time, it upholds the transit state's sovereignty and right to protect its legitimate interests. Consequently, it is important to assess the limits of the transit state's discretion pursuant to the Aktau Convention. In this regard, that instrument has important linkages with UNCLOS and with general international law. These linkages introduce in the Aktau Convention various norms—such as due regard and reasonableness—that play an important role in its interpretation.

4 The Volga-Don canal is the only ingress for over-sized offshore drilling rigs and other support equipment for the Caspian Sea. During the 1995–96 war with Chechnya, the Russian government closed the Volga-Don canal to ships sailing under the Azerbaijani flag. However, Russia had indicated a willingness to sign documents with Azerbaijan over the “question of maintaining joint use of the Caspian Sea's water surface and water mass for purposes of ensuring freedom of navigation and compliance with uniform standards of fishing and environmental protection” (see Timothy L. THOMAS, “Russian National Interests and the Caspian Sea” (1999) 4Perceptions: Journal of International Affairs 75 at 75–96).
