The Treaty of Moscow was signed in August 1970 by representatives of the Soviet Union and West Germany. It sought to end tension between the two nations and is considered an early foundation of Cold War détente:
“The high contracting parties:
Anxious to contribute to strengthening peace and security in Europe and the world;
Convinced that peaceful cooperation among states on the basis of the purposes and principles of the Charter of the United Nations complies with the ardent desire of nations and the general interests of international peace… have agreed as follows:
Article I. The Federal Republic of Germany and the Union of Soviet Socialist Republics consider it an important objective of their policies to maintain international peace and achieve détente. They affirm their endeavour to further the normalisation of the situation in Europe and the development of peaceful relations among all European States, and in so doing proceed from the actual situation existing in this region.
Article II. The Federal Republic of Germany and the Union of Soviet Socialist Republics shall in their mutual relations, as well as in matters of ensuring European and international security, be guided by the purposes and principles embodied in the Charter of the United Nations. Accordingly, they shall settle their disputes exclusively by peaceful means and undertake to refrain from the threat or use of force…
Article III. In accordance with the foregoing purposes and principles, the Federal Republic of Germany and the Union of Soviet Socialist Republics share the realisation that peace can only be maintained in Europe if nobody disturbs the present frontiers.
They undertake to respect without restriction the territorial integrity of all States in Europe within their present frontiers.
They declare that they have no territorial claims against anybody nor will assert such claims in the future.
They regard today and shall in future regard the frontiers of all States in Europe as inviolable, such as they are on the date of signature of the present Treaty, including the Oder-Neisse line which forms the western frontier of the People’s Republic of Poland, and the frontier between the Federal Republic of Germany [West Germany] and the German Democratic Republic [East Germany]…”
