Article 1 Hostilities between Finland and the U.S.S.R. shall cease immediately in accordance with procedure laid down in the protocol appended to this treaty.

Article 2 The national frontier between the Republic of Finland and the U.S.S.R. shall run along a new line in such fashion that there shall be included in the territory of the U.S.S.R. the entire Karelian Isthmus with the city of Viipuri and Viipuri Bay with its islands, the western and northern shores of Lake Ladoga with the cities of Kexholm and Sortavala and the town of Suojarvi, a number of islands in the Gulf of Finland, the area east of Markajarvi with the town of Kuolajarvi, and part of the Rybachi and Sredni peninsulas, all in accordance with the map appended to this treaty.

A more detailed determination and establishment of the frontier line shall be carried out by a mixed commission made up of representatives of the contracting powers, which commission shall be named within ten days from the date of the signing of this treaty.

Article 3 Both contracting parties undertake each to refrain from any attack upon the other and to make no alliance and to participate in no coalition directed against either of the contracting parties.

Article 4 The Republic of Finland agrees to lease to the Soviet Union for thirty years, against an annual rental of eight million Finnish marks to be paid by the Soviet Union, Hanko Cape and the waters surrounding it in a radius of five miles to the south and east and three miles to the north and west, and also the several islands falling within that area, in accordance with the map appended to this treaty, for the establishment of a naval base capable of defending the mouth of the Gulf of Finland against attack; in addition to which, for the purpose of protecting the naval base, the Soviet Union is granted the right of maintaining there at its own expense the necessary number of armed land and air forces.

Within the days from the date this treaty enters into effect, the government of Finland shall withdraw all its military forces from Hanko Cape, which together with its adjoining islands shall be transferred to the jurisdiction of the U.S.S.R. in accordance with this article of the treaty.

Article 5 The U.S.S.R. undertakes to withdraw its troops from the Petsamo area which the Soviet state voluntarily ceded to Finland under the peace treaty of 1920.

Finland undertakes, as provided in the peace treaty of 1920, to refrain from maintaining in the waters running along its coast of the Arctic Ocean warships and other armed ships, excluding armed ships of less than one hundred tons displacement, which Finland shall be entitled to maintain without restriction, and also at most fifteen warships or other armed ships, the displacement of none of which shall exceed four hundred tons.

Finland undertakes, as was provided in the same treaty, not to maintain in the said waters any submarines or armed aircraft.

Finland similarly undertakes, as was provided in the same treaty, not to establish on that coast military ports, naval bases, or naval repair shops of greater capacity than is necessary for the above-mentioned ships and their armament.

Article 6 As provided in the treaty of 1920, the Soviet Union and its citizens are granted the right of free transit across the Petsamo area to Norway and back, in addition to which the Soviet Union is granted the right to establish a consulate in the Petsamo area.

Merchandise shipped through the Petsamo area from the Soviet Union to Norway, and likewise merchandise shipped through the same area from Norway to the Soviet Union, is exempted from inspection and control, with the exception of such control as is necessary for the regulation of transit traffic; neither customs duties nor transit or other charges shall be assessed.


Article 7 The government of Finland grants to the Soviet Union the right of transit for goods between the Soviet Union and Sweden, and, with a view to developing this traffic along the shortest railway route, the Soviet Union and Finland consider it necessary to build, each upon its own territory and insofar as possible in the year 1940, a railway which shall connect Kantalahti (Kandalaksha) with Kemijarvi.
