A wide range of social institutions was set up to nurture relations in both countries. The Hungarian-Finnish Association was established in Hungary in 1937. (After World War II it was not allowed to operate and it could only be reorganised in 1984.) Currently there are 11 friendship organisations in Hungary.

The Finnish-Hungarian Association was established in 1950 in Finland (its predecessor had operated since 1928), and about 50 local organisations were set up over the years. Parallel to this, twin city relationships have developed since 1956. Currently there are 53 twin city and 3 twin village agreements. The latest, 14th conference of twin cities took place on 12-13 June 2019 in Hämeenlinna. Student exchange programmes and cooperation between Lutheran congregations became especially active between the two world wars. Hungary’s European Union membership gave a new impulse to student and teacher exchanges.
