At the Genoa Conference, representatives from 34 nations gather to plan the economic restoration of Central and Eastern Europe. Yet above all, the real focus - not openly declared - was on Great Britain’s plan to form a European common interest group against communist Russia. For its part Russia attempts to conduct bilateral talks with the nations represented at the conference and to negotiate economic and political agreements.

16 April

During the Genoa Conference, dialogue between Russia and Germany deepens. After long hesitation by Rathenau a treaty is signed in the nearby coastal resort of Rapallo on the basis of the talks. The Rapallo Treaty stipulates the renouncement of war-related claims against each other and the resumption of diplomatic relations. Both states also agree a most-favored-nation clause, which stipulates that beneficial trade agreements concluded with other states are also afforded to the contracting partner. Both the Germans and the Russians hope to overcome their international isolation using the treaty.
