Ukrainian President Volodymyr Zelensky emphasized that Hungarian Prime Minister Viktor Orban has “no reason” to obstruct Kyiv’s European Union aspirations, addressing the issue on the eve of an EU summit. Zelensky, in Oslo after talks with five Nordic leaders, challenged Orban to provide even a single reason for the blockade, stating, “Tell me one reason, I’m waiting for (an) answer.”

The EU summit in Brussels aims to reaffirm support for Ukraine, offering a substantial macroeconomic package of 50 billion euros ($54 billion) and the prospect of formal membership talks. However, Orban has threatened to veto both measures, raising the specter of failure for the summit. Such an outcome would leave Ukraine and its neighbor Moldova, also seeking membership talks, in a precarious position nearly two years after Russia’s extensive invasion of Kyiv’s territory.

Hungary asserts principled objections to Ukraine’s bid, contending that Zelensky’s administration, amid wartime challenges, hasn’t sufficiently addressed corruption. Orban, reiterating his opposition on Wednesday, deemed opening EU membership talks with Ukraine a “terrible mistake.”

The geopolitical implications are significant, with Ukraine and Moldova potentially sidelined despite their aspirations for European integration. The veto threat introduces a diplomatic challenge for EU leaders as they convene to navigate the complex dynamics surrounding Ukraine’s bid and broader regional stability.

Zelensky expressed optimism about a “very constructive meeting” with Orban, emphasizing their shared borders. The discussions between the two leaders will likely shape the EU’s approach to Ukraine’s bid and could impact the broader geopolitical landscape in Eastern Europe. As the summit unfolds, the outcome will not only influence the immediate prospects for Ukraine but also set a precedent for EU engagement with neighboring nations seeking closer ties.
