The Russian invasion of Ukraine was widely condemned internationally. The United Nations General Assembly adopted a resolution which condemned it and demanded a full withdrawal. The International Court of Justice ordered Russia to suspend military operations, and the Council of Europe expelled Russia. Many countries imposed new sanctions, which have led to economic consequences for Russia and the world economy. Various countries gave humanitarian and military aid to Ukraine. Protests occurred around the world; those in Russia have been met with mass arrests and increased media censorship, including banning the terms "war" and "invasion". Some companies withdrew their products and services from sale in Russia and Belarus.
The invasion of Ukraine was appraised by many international jurists as a violation of the UN Charter and constituted a crime of aggression according to international criminal law, raising the possibility that the crime of aggression could be prosecuted under universal jurisdiction. The invasion also violated the Rome Statute, which prohibits "the invasion or attack by the armed forces of a State of the territory of another State, or any military occupation, however temporary, resulting from such invasion or attack, or any annexation by the use of force of the territory of another State or part thereof". Ukraine had not ratified the Rome Statute and Russia withdrew its signature from it in 2016.

- [International Court of Justice] Allegations of Genocide under the Convention on the Prevention and Punishment of the Crime of Genocide (Ukraine v. Russian Federation)
This Application concerns a dispute between Ukraine and the Russian Federation relating to the interpretation, application and fulfilment of the 1948 Convention on the Prevention and Punishment of the Crime of Genocide (the “Genocide Convention”). As Ukraine further explains, the Russian Federation has falsely claimed that acts of genocide have occurred in the Luhansk and Donetsk oblasts of Ukraine, and on that basis recognized the so-called “Donetsk People’s Republic” and “Luhansk People’s Republic,” and then declared and implemented a “special military operation” against Ukraine with the express purpose of preventing and punishing purported acts of genocide that have no basis in fact. On the basis of this allegation, Russia is now engaged in a military invasion of Ukraine involving grave and widespread violations of the human rights of the Ukrainian people. Ukraine emphatically denies that any such genocide has occurred and brings this Application to establish that Russia has no lawful basis to take action in and against Ukraine for the purpose of preventing and punishing any purported genocide.

- [International Court of Justice] Application of the International Convention for the Suppression of the Financing of Terrorism and of the International Convention on the Elimination of All Forms of Racial Discrimination (Ukraine v. Russian Federation)
On January 16th, 2017, Ukraine filed a claim with the International Court of Justice requesting the court to initiate proceedings against Russia. Ukraine is accusing Russia of violating the Convention on the suppression of financing terrorism, and the International convention on elimination on all forms of racial discrimination. Ukraine wants not just for the court to order Russia to stop financing terrorists or to stop violating the rights of Crimean Tatars, but also the highest judicial authority within the UN system to recognize that Russia is financing the terrorist in eastern Ukraine, and indeed is violating Human rights of the Crimean Tatars in Crimea.
