This is stated in a letter allegedly signed by the Deputy Minister of Foreign Affairs of Poland, Marcin Przydacz. It is not true.

The letter from the Polish Foreign Ministry is a fake response to a fake letter from the Ukrainian Foreign Ministry. The "letter of response" speaks of a positive decision to rename a street in Warsaw in honor of Stepan Bandera, which houses the Russian embassy. In addition, the "letter" refers to the ways of future promotion of Bandera among the Polish population. According to the Center for Countering Disinformation, a bot account on the social network Facebook, which contains almost no messages of other messages, was likely the primary source.
