According to the terms of the Agreement:
- The northern part of the Karelian Isthmus with the cities of Vyborg and Sortavala , a number of islands in the Gulf of Finland , part of the Finnish territory with the city of Kuolajärvi , part of the Rybachy and Sredny peninsulas departed to the USSR. As a result, Lake Ladoga was completely within the borders of the USSR.
- The USSR leased part of the Hanko Peninsula (Gangut) for a period of 30 years to create a naval base on it.
As a result of the signing of the treaty, the USSR ended up with most of the territory of Karelia returned to the Russian kingdom after the end of the Northern War of Nishtadt in 1721 and which was part of the Russian Empire until 1917.
During the Soviet-Finnish War (1941-1944), Finland occupied, among other things, all territories (except parts of the Sredny and Rybachy peninsulas), which were transferred to the Soviet Union under the Moscow Peace Treaty.
After the end of World War II, the main provisions of the Moscow Peace Treaty were reaffirmed in a peace treaty with Finland , signed in Paris in 1947 .
In the post-Soviet Treaty between the Russian Federation and the Republic of Finland on the foundations of relations , signed in 1992, the territorial changes enshrined in the Moscow Treaty also remained unshakable.
