The Soviet Union, true to the Leninist principles of respect for the rights and national independence of all peoples great or small, has always been and is guided in its relations with other countries by the principles of mutual respect for territorial integrity and sovereignty, non-aggression, non-intervention in each other's internal affairs, equality and mutual benefits, peaceful coexistence and economic cooperation.
