Delimitation of the land boundary with Russia is incomplete, but the parties have agreed to defer demarcation. The [[maritime boundary]] through the [[Sea of Azov]] and the [[Kerch Strait]] remains unresolved despite a December 2003 framework agreement and ongoing expert-level discussions. [[Prime Minister of Russia|Prime Minister]] [[Vladimir Putin]] allegedly declared at a [[NATO]]-Russia summit in 2008 that if [[Ukraine–NATO relations|Ukraine would join NATO]] his country can contend to annex the [[Eastern Ukraine|Ukrainian East]] and [[Crimea]]. As of April 2024, Russia has annexed the Crimean peninsula and partly four other regions of Ukraine: Donetsk, Luhansk, Kherson and Zaporizhzhia.<ref name="The Empirical complex of Russians">{{in lang|uk}} [http://www3.pravda.com.ua/news/2008/7/3/78290.htm The Imperial complex of Russians] {{Webarchive|url=https://web.archive.org/web/20081202023256/http://www3.pravda.com.ua/news/2008/7/3/78290.htm |date=2008-12-02 }}, [[Ukrainska Pravda]] (July 3, 2008)</ref>

Starting in November 2013, the decision by Ukrainian President [[Viktor Yanukovych]] to back out of signing an integration agreement with the [[European Union]] started a [[Revolution of Dignity|period of civil unrest]] between [[Euromaidan|Ukrainians who favored integration with the European Union]] and [[Anti-Maidan|those who wanted closer ties with Russia]]. This culminated in the [[Revolution of Dignity]]. Russia took advantage of this political instability to [[Annexation of Crimea by the Russian Federation|annex Crimea]] in March 2014, though [[Political status of Crimea|Ukraine still claims sovereignty over the territory by any kind of international law]].  [[Russian military intervention in Ukraine (2014-present)|Russia has also allegedly supported quasi-separatist forces]] in the [[War in Donbas (2014–2022)|war in Donbas]].  In December 2015 Russian hackers reportedly [[2015 Ukraine power grid hack|hacked Ukraine's power grids]] leading to a blackout and widespread terror.

On 24 February 2022, diplomatic relations were cut with Russia as a response to the [[Russian invasion of Ukraine]].<ref name=":1"/>
