The article examines the importance and necessity of creating a new international organization designed to take on the role of ensuring regional security. As an example, the Astana process to resolve the Syrian crisis, which was created with the participation of Russia, Iran and Turkey, is considered. Thus, the countries demonstrated the ability to take responsibility for ensuring regional security in the conflict zone. Russia, Iran and Türkiye were able to develop specifi c ways to resolve this crisis situation. Using the experience of the Astana format, such major players as Russia, Türkiye and Iran could find ways to solve other international problems. And here they may be joined by another influential world power — China. The strength of the new international security architecture will depend on these states. China has long played an important role in maintaining global stability. And here we can note the special role of mediation diplomacy, which has recently become the most striking calling card of Chinese diplomacy. Thus, in March 2023, with the participation of China, a historic reconciliation between Saudi Arabia and Iran took place. In light of the recent escalation of the Palestinian-Israeli confl ict, China has published a position paper on a political solution to the crisis. The document off ers recommendations to resolve the problem, namely, a complete cessation of hostilities, protection of civilians, provision of humanitarian assistance, strengthening diplomatic mediation and the search for a political settlement. The authors come to the conclusion that, taking into account the accumulated experience in fi nding ways to resolve acute regional conflicts, and by joining forces, Russia, China, Iran and Türkiye are able to create an international structure for resolving crisis situations, which will become a guarantor for ensuring international security and stability.
