Hungary Rejects Carpathian Eight Forum and Oil Storage Deal, Deepening Ukraine Tensions

Key points

• Hungarian Prime Minister Peter Magyar stated that Budapest declined an invitation to join the Carpathian Eight summit, which was held in Ivano-Frankivsk Oblast on September 18.
• The forum, aimed at boosting regional investment and security, was attended by leaders from Poland, Romania, Serbia, Czechia, Austria, and Slovakia, but Hungary was absent from the group photo and opening speeches.
• Magyar also blocked a memorandum between Ukraine’s Naftogaz and Hungarian company MOL regarding oil storage facilities in Hungary, warning MOL to consult the government before proceeding.
• Ukraine’s Foreign Minister Andrii Sybiha criticized Hungary’s stance as confrontational, suggesting it mirrors the isolationist policies of former Prime Minister Viktor Orbán.
• Budapest continues to veto Ukraine’s EU accession talks, citing unresolved issues regarding the rights of the Hungarian minority in Ukraine, despite a previous agreement on minority rights.

Background

Relations between Hungary and Ukraine saw a partial thaw after Peter Magyar took office in May 2026, replacing Viktor Orbán. Magyar initially signaled interest in resetting ties and lifting vetoes on EU aid, but tensions have resurfaced over minority rights and energy cooperation. Previous EU court rulings have blocked Hungary from halting aid funded by frozen Russian assets, highlighting ongoing legal and political disputes.

How outlets are covering it

The Kyiv Independent and Kyiv Post emphasize Hungary’s formal rejection of the Carpathian Eight and the diplomatic fallout, noting that Hungary was listed as a member despite its refusal. Euronews highlights the clash between Magyar and Sybiha on social media, with Magyar comparing the situation to a football team signing an unknown player. Ukrainska Pravda focuses on the oil storage dispute, detailing MOL’s claim that the process is still in early stages and that the government was not notified due to the preliminary nature of the talks. All sources agree that Hungary’s actions are seen as a setback for the reset in relations, with Kyiv accusing Budapest of continuing Orbán’s obstructionist approach.

Why it matters

Hungary’s rejection of the Carpathian Eight and the oil storage deal signals a significant obstacle to regional cooperation and energy security in Eastern Europe. It also underscores the fragility of the recent diplomatic thaw between Hungary and Ukraine, with Budapest’s continued vetoes on EU accession talks threatening to stall Kyiv’s integration into the EU. This dispute could have broader implications for EU unity and energy policy in the region.

What to watch

A potential meeting between Zelensky and Magyar remains unscheduled, with Kyiv’s advisor Dmytro Lytvyn indicating that the delay is on Hungary’s side. The outcome of the MOL-Naftogaz negotiations and Hungary’s stance on EU accession talks will be critical in determining the future of bilateral relations. Further diplomatic efforts may be needed to address minority rights and energy cooperation to prevent a deeper rift.
