Treaty of Friendship, Cooperation and Mutual Assistance Between the People’s Republic of Albania, the People’s Republic of Bulgaria, the Hungarian People’s Republic, the German Democratic Republic, the Polish People’s Republic, the Rumanian People’s Republic, the Union of Soviet Socialist Republics and the Czechoslovak Republic, May 14, 1955
The Contracting Parties, reaffirming their desire for the establishment of a system of European collective security based on the participation of all European states irrespective of their social and political systems, which would make it possible to unite their efforts in safeguarding the peace of Europe; mindful, at the same time, of the situation created in Europe by the ratification of the Paris agreements, which envisage the formation of a new military alignment in the shape of “Western European Union,” with the participation of a remilitarized Western Germany and the integration of the latter in the North-Atlantic bloc, which increased the danger of another war and constitutes a threat to the national security of the peaceable states; being persuaded that in these circumstances the peaceable European states must take the necessary measures to safeguard their security and in the interests of preserving peace in Europe; guided by the objects and principles of the Charter of the United Nations Organization; being desirous of further promoting and developing friendship, cooperation and mutual assistance in accordance with the principles of respect for the independence and sovereignty of states and of noninterference in their internal affairs, have decided to conclude the present Treaty of Friendship, Cooperation and Mutual Assistance and have for that purpose appointed as their plenipotentiaries:
who, having presented their full powers, found in good and due form, have agreed as follows:
The Contracting Parties undertake, in accordance with the Charter of the United Nations Organization, to refrain in their international relations from the threat or use of force, and to settle their international disputes peacefully and in such manner as will not jeopardize international peace and security.
The Contracting Parties declare their readiness to participate in a spirit of sincere cooperation in all international actions designed to safeguard international peace and security, and will fully devote their energies to the attainment of this end.
The Contracting Parties will furthermore strive for the adoption, in agreement with other states which may desire to cooperate in this, of effective measures for universal reduction of armaments and prohibition of atomic, hydrogen and other weapons of mass destruction.
The Contracting Parties shall consult with one another on all important international issues affecting their common interests, guided by the desire to strengthen international peace and security.
They shall immediately consult with one another whenever, in the opinion of any one of them, a threat of armed attack on one or more of the Parties to the Treaty has arisen, in order to ensure joint defence and the maintenance of peace and security.
In the event of armed attack in Europe on one or more of the Parties to the Treaty by any state or group of states, each of the Parties to the Treaty, in the exercise of its right to individual or collective self-defence in accordance with Article 51 of the Charter of the United Nations Organization, shall immediately, either individually or in agreement with other Parties to the Treaty, come to the assistance of the state or states attacked with all such means as it deems necessary, including armed force. The Parties to the Treaty shall immediately consult concerning the necessary measures to be taken by them jointly in order to restore and maintain international peace and security.
Measures taken on the basis of this Article shall be reported to the Security Council in conformity with the provisions of the Charter of the United Nations Organization. These measures shall be discontinued immediately the Security Council adopts the necessary measures to restore and maintain international peace and security.
The Contracting Parties have agreed to establish a Joint Command of the armed forces that by agreement among the Parties shall be assigned to the Command, which shall function on the basis of jointly established principles. They shall likewise adopt other agreed measures necessary to strengthen their defensive power, in order to protect the peaceful labours of their peoples, guarantee the inviolability of their frontiers and territories, and provide defence against possible aggression.
For the purpose of the consultations among the Parties envisaged in the present Treaty, and also for the purpose of examining questions which may arise in the operation of the Treaty, a Political Consultative Committee shall be set up, in which each of the Parties to the Treaty shall be represented by a member of its Government or by another specifically appointed representative.
The Committee may set up such auxiliary bodies as may prove necessary.
The Contracting Parties undertake not to participate in any coalitions or alliances and not to conclude any agreements whose objects conflict with the objects of the present Treaty.
The Contracting Parties declare that their commitments under existing international treaties do not conflict with the provisions of the present Treaty.
The Contracting Parties declare that they will act in a spirit of friendship and cooperation with a view to further developing and fostering economic and cultural intercourse with one another, each adhering to the principle of respect for the independence and sovereignty of the others and non-interference in their internal affairs.
The present Treaty is open to the accession of other states, irrespective of their social and political systems, which express their readiness by participation in the present Treaty to assist in uniting the efforts of the peaceable states in safeguarding the peace and security of the peoples. Such accession shall enter into force with the agreement of the Parties to the Treaty after the declaration of accession has been deposited with the Government of the Polish People’s Republic.
The present Treaty is subject to ratification, and the instruments of ratification shall be deposited with the Government of the Polish People’s Republic.
The Treaty shall enter into force on the day the last instrument of ratification has been deposited. The Government of the Polish People’s Republic shall notify the other Parties to the Treaty as each instrument of ratification is deposited.
The present Treaty shall remain in force for twenty years. For such Contracting Parties as do not at least one year before the expiration of this period present to the Government of the Polish People’s Republic a statement of denunciation of the Treaty, it shall remain in force for the next ten years.
Should a system of collective security be established in Europe, and a General European Treaty of Collective Security concluded for this purpose, for which the Contracting Parties will unswervingly strive, the present Treaty shall cease to be operative from the day the General European Treaty enters into force.
Done in Warsaw on May 14, 1955, in one copy each in the Russian, Polish, Czech and German languages, all texts being equally authentic. Certified copies of the present Treaty shall be sent by the Government of the Polish People’s Republic to all the Parties to the Treaty.
