United Nations (UN) peacekeeping missions are under political and financial pressure. In his letter dated 10 October 2025, UN Secretary-General António Guterres called on nine missions to prepare contingency plans for spending cuts of up to 25 per cent. The peacekeeping mission in Cyprus (UNFICYP), established in 1964, shows why Europe has a fundamental interest in the UN remaining engaged.

The conflict between the Republic of Cyprus in the Greek-speaking south and the Turkish Republic of Northern Cyprus, the Turkish-speaking region recognised only by Ankara, has been largely frozen since the de facto division of the island. This certainly has also been due to UNFICYP’s presence. Since the 1974 ceasefire, the mission has controlled the “Green Line”, a 180-kilometre strip separating the two parts that is intended to prevent direct confrontation.

Nevertheless, the mission continues to record numerous military and civilian violations in and along the buffer zone By doing so, it still prevents “those sparks from bursting into flames”, as Colin Stewart, head of UNFICYP until August 2025, put it. To this day, there still is no direct military contact mechanism between the parties. In fact, the threat perception has increased again on both sides recently.

New impetus for peace efforts

For this reason alone, the European Union and its member states cannot be interested in any further reduction or even a potential withdrawal of the mission. The political process is just beginning to tentatively gain momentum. María Angela Holguín Cuéllar was reappointed as the Secretary-General’s Personal Envoy in May 2025 and is tasked with exploring possibilities for a new round of formal negotiations and breaking the deadlock. 

This is a difficult undertaking. While the UN Security Council continues to pursue a federal solution, Northern Cyprus and Turkey have been promoting a two-state solution for years. However, the election of Turkish Cypriot President Tufan Erhürman in October has raised hopes that the door could open for new negotiations under UN auspices. The first trilateral meeting between him, the President of the Republic of Cyprus, and Holguín has just taken place. But a rapprochement is likely to take time. Confidence-building measures and the safeguarding of peace by the UN therefore remain essential.

The essential role of the UN

As the Republic of Cyprus is a member of the EU, the Union itself can hardly act as an impartial mediator. It therefore primarily supports the UN-led political process. The EU’s options in the security domain are also constrained. A separate EU mission – as is currently being considered for Lebanon following the withdrawal of UNIFIL – would be unrealistic, if only because of the tense relationship between Greece and Turkey, both of which, alongside the United Kingdom, are the guarantor powers for Cyprus. 

Therefore, the stabilising function of the UN mission remains essential for the foreseeable future. It also creates the framework for practical rapprochement, for example through the projects of the Technical Committees. Under joint Greek Cypriot and Turkish Cypriot leadership and facilitated by the UN, these initiatives promote understanding between the two communities, and the EU provides a large portion of the funding. 

UNFICYP is in a better financial position than many larger UN missions, as Greece and the Republic of Cyprus cover about half of the budget. However, staffing and operational cuts will be necessary. At the same time, the raison d'être of a mission that has been running for decades is repeatedly being called into question. At the end of January 2026, the mandate is up for renewal again. Despite all the criticisms from the Turkish government and former leaders in Northern Cyprus, the UN Security Council's position has remained unchanged so far. 

In order to break the deadlock in negotiations, there is a need for more economic engagement from the European side to improve the situation in the north. In the short term, however, EU member states should make it clear that UNFICYP – and UN peacekeeping as a whole – is indispensable.
