The Russia–United States maritime boundary was established by the June 1, 1990 USA/USSR Maritime Boundary Agreement ^[1] (since Russia declared itself to be the successor of the Soviet Union). The United States Senate gave its advice and consent to ratification as early as on September 16, 1991, but it has yet to be approved by the Russian State Duma. This delimitation line is also known as the Baker-Shevardnadze line or Baker-Shevardnadze agreement, after the officials who signed the deal, Minister of Foreign Affairs of the Soviet Union Eduard Shevardnadze and U.S. Secretary of State James Baker.^[2] The 1990 Agreement has been provisionally applied by the two countries since its date of signature. (The Russian Federation is the successor of the USSR with respect to the 1990 Agreement and the agreement to provisionally apply it.)

In general concept, the 1990 line is based on the 1867 United States – Russia Convention providing for the U.S. purchase of Alaska. From the point, 65° 30' N, 168° 58' 37" W the maritime boundary extends north along the 168° 58' 37" W meridian through the Bering Strait and Chukchi Sea into the Arctic Ocean as far as permitted under international law. From the same point southwards, the boundary follows a line specified by maritime geographic positions given in the Agreement.^[1]

The need for the maritime boundary arose with the introduction of the 200-mile limit by the United States and the Soviet Union. The United States proposed using the 1867 Alaska line because it understood that to be the likely Soviet position. ^[3] The 1990 delimitation was complicated since neither side could produce the maps used during the original Alaska purchase negotiations. Furthermore, the two sides agreed that the boundary was intended to be a straight line on a map, but they did not agree which map projection was used: Mercator or conformal. This resulted in about 15,000 square nautical miles (51,000 km²) of disputed area. The 1990 line split the difference between the two lines and introduced several "special areas", which were beyond the 200-mile zone, but in which the sides ceded their rights to the opponent.

Many in Russia have criticized Mikhail Gorbachev and Edvard Shevardnadze for rushing the deal, ceding Russian fishing rights and other maritime benefits, but Foreign Minister Sergey Lavrov recently defended the agreement as being in the interest of all parties.^[4]
