Foreign ministers from eight nations, including the R4 group (Turkey, Egypt, Pakistan, and Saudi Arabia) and the E3/E4 group (France, Germany, the United Kingdom, and Italy), convened in Istanbul to address escalating regional tensions and security threats.

Initial discussions focused on the need for diplomacy to prevent the expansion of conflicts involving the US, Iran, and Israel, as well as the humanitarian crisis in Yemen. Participants raised specific concerns regarding the safety of international shipping routes in the Black Sea, the Strait of Hormuz, and the Bab el-Mandeb strait, noting that renewed hostilities could impact global energy markets.

By the conclusion of the summit, the ministers issued a joint communique emphasizing UN-aligned resolutions. Regarding the Israel-Palestine situation, the group called for an immediate two-state solution based on 1967 borders and an end to Israeli settlement activities and violence. Additionally, the group condemned Houthi militia attacks against commercial vessels in the Red Sea and the Yemeni government, demanding a cessation of military actions to protect global supply chains.
