Ukraine paid an average of $305 in the first quarter of 2010 and $330 in the second quarter. Mid-April Ukrainian officials stated they are seeking an average price of $240–$2 cubic metres for 2010. Following these talks Russian Prime Minister Vladimir Putin stated that Russia was prepared to discuss the revision of the price for natural gas it sells to Ukraine. The Prime Minister of Ukraine, Mykola Azarov, and the Energy Minister, Yuriy Boyko, visited Moscow in late March 2010 to negotiate lower gas prices neither clearly explained what Ukraine was prepared to offer in return. Īmid several Russia–Ukraine gas disputes, including a halt of natural gas supplies to European countries, the price that Ukraine had to pay for Russian natural gas was raised in 2006 and in 2009. During the presidency of Victor Yushchenko (January 2005 – February 2010) the Ukrainian government declared that the lease would not be extended and that the fleet would have to leave Sevastopol by 2017. Ukraine also agreed to lease major parts of its new bases in Sevastopol to the Russian Black Sea Fleet until 2017.

In 1997, Russia and Ukraine signed the Partition Treaty, establishing two independent national fleets and dividing armaments and bases between them. Shortly after the annexation of Crimea by the Russian Federation in March 2014, Russia unilaterally terminated the treaty on 31 March 2014. The treaty was effectively a continuation of the lease provisions that were part of the 1997 Black Sea Fleet Partition Treaty between the two states. The agreement, signed on 21 April 2010 in Kharkiv, Ukraine, by Ukrainian President Viktor Yanukovych and Russian President Dmitry Medvedev and ratified by the parliaments of the two countries on 27 April 2010, aroused much controversy in Ukraine. The Agreement between Ukraine and Russia on the Black Sea Fleet in Ukraine, widely referred to as the Kharkiv Pact ( Ukrainian: Харківський пакт) or Kharkov Accords ( Russian: Харьковские соглашения), was a treaty between Ukraine and Russia whereby the Russian lease on naval facilities in Crimea was extended beyond 2017 until 2042, with an additional five-year renewal option in exchange for a multiyear discounted contract to provide Ukraine with Russian natural gas.
