67.3 percent said they strongly supported or rather supported such a ban. 20 percent were against, and 12.6 percent did not answer the question.
Mantas Martisius, an associate professor at Vilnius University's Communication Faculty, says the number of those in favor of the ban is high, reflecting the society's information literacy.
The public display of the St George's Ribbon and the two mentioned letters was banned in Lithuania after the Russian invasion of Ukraine was launched.
As Russia and Russian communities abroad celebrate the Soviet Union's victory over Nazi Germany in WWII on Monday, Lithuanian officials fear possible provocations in the country over the public use of these symbols.
The survey also shows support among Lithuanian residents for a ban on the entry of artists from Russia, as well as a ban on their concerts, exhibitions and other performances.
58.3 percent would agree with such a ban, while 25.3 percent would disagree. 16.4 percent did not answer the question.
