Türkiye's Global Diplomacy: UN Reform, Gaza, Mediation and COP31

Why It Matters

Türkiye's multilateral agenda rests on one claim: that the post-1945 UN order is too narrow to manage today's crises. Ankara pairs its call for Security Council reform, summed up in the phrase The world is bigger than five, with practical diplomacy on Gaza, Russia–Ukraine mediation, regional organizations and climate, culminating in its role as host of COP31 in 2026. This guide ties each strand to primary documents (Turkish Ministry of Foreign Affairs, Presidency and UN texts) and summarizes how partners and critics assess it.

Background

How the Security Council works, and why reform is stuck

The UN Security Council has 15 members: five permanent (China, France, Russia, the United Kingdom and the United States) and ten elected for two-year terms. Under Article 27(3) of the UN Charter, each permanent member can veto substantive decisions. The elected category grew from six to ten members through an amendment to Article 23 adopted by the General Assembly in 1963 and in force since 1965; that remains the only enlargement in the Council's history.

Any further change requires an amendment under Article 108: a two-thirds vote in the General Assembly and ratification by two-thirds of members, including all five permanent members. The General Assembly's Intergovernmental Negotiations (IGN) on Council reform began in 2008 (decision 62/557) and have produced no agreed text. In April 2022 the Assembly adopted resolution 76/262, which requires a debate within ten working days after any veto. This is the most concrete reform step in recent years.

Chronology of Türkiye's multilateral milestones

Key Players & Positions

Competing Security Council reform models

No single model commands the two-thirds majority and the P5 consent that Article 108 demands. The main proposals differ mainly on permanent seats and the veto.

The P5 are not uniform. In September 2024 the United States said it supported two permanent African seats without veto power. France and the United Kingdom have publicly backed expanding both categories of membership. China has emphasized more representation for developing countries. Each of these positions is stated in the speeches the countries give to the General Assembly and in their IGN submissions.

Gaza and Palestine

Israel says its campaign in Gaza after the 7 October 2023 attacks is self-defense under Article 51 of the UN Charter and rejects accusations of genocide. Hamas is designated a terrorist organization by the United States and the European Union; Türkiye does not use that designation. Egypt and Qatar have been central mediators alongside the United States. Several Western governments have criticized Ankara's contacts with Hamas leaders. Israeli officials have also objected to a Turkish military role in any post-war Gaza arrangement.

Russia–Ukraine

Ukraine has welcomed Turkish mediation and drones alike, while asking Ankara to go further on sanctions. Russia values Türkiye as a channel and a trade partner. NATO allies have appreciated Türkiye's Montreux implementation but have criticized its decision not to join Western sanctions. Details of the straits regime are covered in The 1936 Montreux Convention: How Türkiye Governs the Turkish Straits.

Climate

The COP31 compromise reached at COP30 reflects competing bids from Türkiye and Australia within the Western European and Others Group. Under the arrangement reported after Belém, Türkiye holds the host role and presidency in Antalya in 2026, while Australia leads negotiations. Climate groups note that Türkiye was the last G20 member to ratify the Paris Agreement (October 2021), that coal still plays a major role in its energy mix, and that it has set a 2053 net-zero target.

Source Comparison

The same events are often framed differently by international outlets and Turkish official sources. Readers should compare both against the underlying documents.

The fairest reading is that both sides cite real facts. Türkiye has demonstrably hosted talks and signed the grain deal, and critics are right that its sanctions policy, energy mix and disputes with neighbors affect how its credibility as a mediator is judged.
