In 2014, President of Ukraine Petro Poroshenko considered the option of giving up Crimea to Russia in return for membership in NATO and the European Union. The situation in Ukraine is similar to what happened to Georgia. It is already clear that Abkhazia and South Ossetia will not return to Georgia. However, the loss of Crimea can be used to acquire membership in the EU and NATO.
Recurring pro-Kremlin disinformation narrative about Crimea.
President of Ukraine Petro Poroshenko, representatives of the European Union and NATO have consequently declared their position on the illegal annexation of Crimea by Russia. For example, during his speech at the Ukrainian breakfast in Davos in 2019, Petro Poroshenko clearly repeated his message about the fact that Crimea should return under the control of Kyiv. Moreover, Poroshenko signed the decision of the Parliament of Ukraine in which Crimea is recognised "temporarily occupied", while Russia is an occupying state.
The European Union does not recognise the annexation of Crimea and Sevastopol. On February 19, 2019, the President of the European Council, Donald Tusk, during a speech in the Verkhovna Rada of Ukraine on the occasion of the fifth anniversary of the armed aggression of Russia, once again assured that Europe would never recognise the annexation of Crimea by Russia and would not stop sanctions. See here for the EU statement on the fifth anniversary of Crimea annexation.
In turn, the Secretary General of NATO Jens Stoltenberg spoke publicly about the illegality of the annexation and the necessity of returning Crimea to Ukraine following the meeting of the foreign ministers of the member countries and the foreign ministers of Ukraine and Georgia in 2018.
The United Nations General Assembly adopted a resolution, which condemned Russia's illegal actions in Ukraine.
