"We will, of course, not react to such a statement of low culture. In general, it's deplorable that it's not the first time we have to evaluate our neighbor based on such reflections of low personal culture," Kubilius told the Lithuanian Radio on Tuesday.
His comments followed Belarusian President Lukashenko's statement about a recent attack on Lithuania's Embassy in Minsk.
"These people are not terrorists; you shouldn't see any terrorists here," Lukashenko said during a meeting with the students and faculty of Belarusian State Economics University on Monday. He was quoted by Russian news agency Interfax.
The Belarusian president also said that Molotov cocktails were thrown into the territory of Russia's Embassy in Minsk in 2010. People behind this attack were arrested and punished, Lukashenko said.
"Lithuania was shouting that they [people convicted for the incident on the territory of the Russian Embassy] are now political prisoners. When they threw those bottles [on the territory of the Lithuania Embassy], it was terrorism. It's their policy, it's a bad policy," Lukashenko said, according to Interfax.
Two Molotov cocktails were thrown into the territory of the Lithuanian Embassy in Minsk on the evening of 6 November. The fire was swiftly put out by Lithuanian police officers guarding the embassy.
Belarusian Ambassador to Lithuania Vladimir Drazhin was later summoned to the Lithuanian Ministry of Foreign Affairs over the incident.
Belarusian law enforcement institutions launched an investigation into hooliganism.
Lithuanian Minister of Foreign Affairs Audronius Ažubalis and Emanuelis Zingeris, chairman of the parliamentary Committee on Foreign Affairs, called the incident a terrorist attack.
