KIEV, July 30. /TASS/. Ukraine’s Foreign Ministry has remonstrated to Russia a yet another time over a trip to Crimea by Prime Minister Dmitry Medvedev, the press service of the ministry said on Monday.

The ministry claimed Dmitry Medvedev’s visit meant "crude violation of Ukraine’s state sovereignty and territorial integrity" and was an instance of "a cynical and defiant disregard of the commonly accepted norms of international law."

Medvedev is making a trip to Crimea to chair a conference on the region’s social and economic development. On Sunday, July 29, he attended a naval review making Navy Day.

Following the state coup in Kiev in February 2014 that was applauded by Washington and its allies and on the face of a growing chaos and the onslaught of ultra-rightwing outrage across Ukraine, the Supreme Soviet of Crimea and the City Hall of Sevastopol adopted a declaration of independence from Ukraine on March 11.

On March 16, the residents of Crimea and Sevastopol held a referendum for reunification with Russia, with the turnout of 80% of registered voters. The proposal to reunify with Russia was supported by 96.77% voters in the Republic of Crimea and 95.6% in Sevastopol.

A treaty on accession of the new constituent territories to the Russian Federation was signed on March 18.

The US, the EU and the government in Kiev refused to recognize the fact of Crimea’s reunification with Russia.
