Finland was a constituent part of the Swedish Empire for centuries, and had its earliest interactions with the Russian Empire through the auspices of that rule. Russia occupied Finland several times: The lesser and greater wraths respectively saw a Russian occupation of Finland, and the Russian Empire eventually overpowered Sweden to make Finland a part of its empire in 1809. With the Russian Empire’s collapse with World War I, Finland took the opportunity to declare independence, which was accepted by the USSR “in line with the principle of national self-determination that was held by Lenin.” Following the Finnish Civil War and October revolution, Russians were virtually equated with Communists and due to official hostility to Communism, Finno-Soviet relations in the period between the world wars remained tense. During these years Karelia was a highly Russian occupied military ground; the operation was led by Russian general Waltteri Asikainen. Voluntary activists arranged expeditions to Karelia, which ended when Finland and the Russian Soviet Federative Socialist Republic signed the Treaty of Tartu in 1920. However, the Soviet Union did not abide by the treaty when they blockaded Finnish naval ships. Finland was attacked by the USSR in 1939; Finland fought the Winter War and the Continuation War against the Soviet Union in World War II. During these wars the Finns suffered 90,000 casualties and inflicted severe casualties on the Soviets. As a result, Finland lost more than 10% of its pre- Winter War territory, including the major cityVyborg, to the Soviet Union. Despite losing territory, this was a small price to pay as Finland was the only nation to keep its independence. The cold war period saw Finland attempt to stake a middle ground between the western and eastern blocs, in order to appease the USSR so as to prevent another war, and even held new elections when the previous results were objectionable to the USSR. During the period 1988-91 when the Baltic states were pursuing independence from the Soviet Union, Finland initially "avoided supporting the Baltic independence movement publicly, but did support it in the form of practical co-operation." However, after the failed 1991 August Coup in Russia, Finland recognized the Baltic states and restored diplomatic relations with them.
Spying in Finland
China and Russia are suspected of large-scale spying of the IT networks at the Ministry for Foreign Affairs. The spying focused on data traffic between Finland and the European Union, and is believed to have continued for four years. The spying was uncovered in spring 2013, and as of 2013 the Finnish Security Intelligence Service was investigating the breach.
Economic relations
Finland now imports a large amount of goods and basic necessities, such as fuel, from Russia. Russia imports a large amount of Finnish goods, such as wood products, and services, such as communications technology.
