KIEV, March 21 - Ukraine's foreign ministry has registered its strong protest against the visit of March 18 - the second anniversary of Russia's annexation of Crimea - to the disputed peninsula by Russian President Vladimir Putin and other Russian officials.

The ministry said the visit was “yet another uncoordinated with Ukraine“ trip to the “temporarily occupied territory – the Autonomous Republic of Crimea."

"Ukraine and all democratic nations of the world will double their efforts to free residents of the Ukrainian peninsula from authoritarian rule of the occupation regime and to make Crimea free again," the ministry said in a statement regarding the visit.
