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 Romanian People's Republic, the Union of Soviet Socialist Republics and the Czechoslovak Republic

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 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.

Article 5

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.

Article 9

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.
