Modern international relations are marked by increased instability, the emergence of new armed conflicts and exacerbation of old ones, threats coming from international terrorism, as well as challenges to international peace and security. In such conditions, not a single subject of international law is able to cope with these negative trends alone. In this regard, collective efforts of states at the sites of international intergovernmental organizations, as well as the expansion of inter-organizational cooperation, in particular between the UN and the OIC, can make a significant contribution to collective measures to maintain international peace and security and ensure human rights in the modern world. Azerbaijan's proposals to develop a model of a global-regional partnership in the framework of cooperation between the UN and the OIC are designed to strengthen the international security system, intensify the fight against the growing geography of international terrorism and extremism, and also promote the ideas of tolerance and multiculturalism.
