"The Ministry of Foreign Affairs of Ukraine expresses strong protest in connection with the next visit of the President of the Russian Federation Vladimir Putin on August 10, 2019, which was not agreed with the Ukrainian side," the statement said.
Earlier it was reported that Putin arrived at the Night Wolves bike show in Crimea and congratulated the motorcycle club on the 10th anniversary of the event on the peninsula.
Also at the end of July, the Ukrainian Foreign Ministry protested over the trip of Russian Prime Minister Dmitry Medvedev to Crimea.
Crimea became the Russian region after a referendum held in March 2014, in which most residents spoke out for reunification with Russia.
