On Wednesday, Russian President Vladimir Putin traveled to Yalta on the contested Crimean peninsula, where he addressed a forum by the All-Russia People’s Front, a political movement Putin started in 2011 to coexist with the United Russia political party.
Hours after Putin’s speech, the Ukrainian Foreign Ministry sent Moscow a formal letter of protest, claiming that Putin failed to obtain Kiev’s permission to set foot in “Ukrainian territory occupied by the Russian Federation.” This wasn’t the first time Ukraine has sent such a letter, and it’s not likely to be the last.
