The Republic of Poland in the United Nations Security Council (2018 – 2019) and the Ukrainian Question

The purpose of the paper is to highlight the activities of the representatives of the Republic of Poland in the UN Security Council in the status of a non-permanent member in 2018-2019, in particular regarding the resolving of the Russian-Ukrainian conflict. The method of content analysis of state program documents, Internet portals of the government of the Republic of Poland and the United Nations, and scientific literature was used in the implementation of the goal. The problem-chronological method made it possible to trace the history of the participation of the Republic of Poland in the UN. The methodology is based on the principles of historicism and objectivity. The scientific novelty of the research lies in the new understanding of the role of Polish diplomacy in the UN Security Council after the occupation of Crimea and the start of Russia's hybrid war in Donbas. The analysis made it possible to formulate the following conclusions. The Republic of Poland – one of the founding states of the UN – tried to be an active member of the organization, including by participating in the work of its main bodies. Poland was elected a non-permanent member of the Security Council six times. The main priorities of Polish diplomacy at the UN Security Council in 2018-2019 included: respect for international law, protection of civilians in armed conflicts, peace and security in Eastern Europe. Much attention was paid to the issue of the Russian-Ukrainian conflict, which, thanks to the Polish side, did not disappear from the body's agenda and was discussed in various contexts. The Polish delegates consistently reminded about the negative impact of the violation of international law and agreements by the Russian Federation, the situation in the occupied territories of Crimea and Donbas, and in the Black and Azov seas. They tried to present the consequences of the occupation of Crimea and the war in Donbas not only as a problem of regional security, but also as a global challenge to the international legal order. The Polish state made a significant contribution to the formation and strengthening of the international coalition in support of Ukraine in countering the aggression of the Russian Federation. An obstacle to an effective resolution of the Ukrainian issue was primarily the specificity and composition of the UN Security Council, where non-permanent members play only a limited role, and one of the permanent members is an aggressor country. The example of the debate surrounding the resolution of the Ukrainian issue once again proves the deficit of UN deep reform
