EU imposes sanctions on Mikhail Piotrovsky, director of Russia's State Hermitage Museum

The European Union has imposed sanctions on Mikhail Piotrovsky, the director of Russia's State Hermitage Museum, as part of its 20th sanctions package adopted on 23 April. Piotrovsky, a vocal supporter of Russia's full-scale invasion of Ukraine, is cited for being a close associate of Vladimir Putin and for actively supporting the war, including justifying Russian cultural policies that incorporate Ukrainian museum items into Russia's State Museum Fund and enabling unauthorized archaeological excavations in occupied Crimea. The sanctions also target three other cultural officials involved in the Crimean digs. Meanwhile, Hermitage archaeologist Alexander Butyagin, arrested in Poland in December 2025 at Ukraine's request, was released in a prisoner exchange on 28 April.
