Which treaty aimed to re-establish diplomatic relations between the USSR and Germany?

The Rapallo Treaty, signed in 1922 between the USSR and Germany, aimed to re-establish diplomatic relations and foster economic cooperation between the two countries following World War I. After the war, both nations faced international isolation due to the punitive measures imposed by the Treaty of Versailles on Germany and the political situation of the Bolshevik Revolution in Russia. The Rapallo Treaty was significant as it allowed both countries to circumvent these treaties and pursue mutual interests, including military cooperation and economic exchanges.

This treaty exemplified a pragmatic approach to international relations, enabling Germany and the USSR to strengthen ties, share resources, and engage in joint projects despite their respective political ideologies at the time. The cooperation established through the Rapallo Treaty laid the groundwork for future agreements and highlighted the geopolitical realignments in Europe during the interwar period.

The other treaties listed serve different purposes or address distinct issues and therefore do not fit the context of re-establishing relations specifically between the USSR and Germany.
