Ukrainian President Volodymyr Zelensky publicly announced on 18 September 2026 the creation of a new regional cooperation format — the Carpathian Eight (C8), bringing together the states of the Carpathian macroregion. Two days later, on 20 September, the head of state summarized the outcomes of the first C8 summit in his Telegram channel, emphasizing that it was on this platform that the Carpathian Integration Initiative was launched. In his words, the new format will become a strategic pillar for Ukraine on its path to joining the European Union, while the combined economic potential of joint projects is estimated at "billions of euros".

### Carpathian Integration Initiative: from declarations to projects

Zelensky stated that the first C8 summit made it possible to "jointly lay the foundation for the Carpathian Integration Initiative" — a mechanism designed to systematize cooperation among the macroregion's countries in the fields of security, energy, and the economy. The president called on allies to "deliver everything that is currently planned" and promised to attract additional resources and opportunities to support cross-border interaction between communities. "Let the EU's Carpathian macroregion remain strong. And let this format be our support on the path to joining the European Union," he wrote, addressing the leaders of the C8 countries, business representatives, and Carpathian communities.

### Mountain challenges: the specifics of the macroregion

Zelensky placed particular emphasis on the uniqueness of the Carpathian region. "There is a specific character here, in the Carpathians: mountain communities, and therefore mountain roads, their own social challenges, their own ecological challenges," the president explained. In his view, a significant portion of these problems cannot be solved unilaterally and requires precisely a cross-border, joint approach. This, in essence, justifies the need for ongoing institutional dialogue between the eight states and Brussels.

### What is the Carpathian Eight and who is a member of it

The Carpathian Eight (C8) is a cooperation format bringing together eight states of the Carpathian macroregion: Ukraine, Romania, Poland, the Czech Republic, Slovakia, Hungary, Serbia, and Austria, as well as the European Union as a whole as an institutional partner. The main goal of the format is to strengthen cooperation among the region's countries in three key areas: security, energy, and the economy. As Ukrainian media report, Zelensky recently revealed the first official agreements among all C8 participants, indicating that the format is moving from a declaratory phase to practical implementation.

### Contradictory data

Fact-checking revealed a discrepancy in the chronology. The main text and Ukrainian sources (RBC-Ukraine, novosti.ua, hvylya.net) unambiguously point to 18 September 2026 as the date of the public announcement of C8's creation and the holding of the first summit. However, the verified sources database contains an RFI (rfi.fr) article with a URL containing the date 12 July 2023 and the headline "The results are good, but if there had been an invitation, they would have been perfect." This may indicate either an earlier, preceding contact at the C8 level, or that the RFI link refers to a different event. In any case, confirming the exact date of the first C8 summit in 2026 requires additional verification by the editorial team.

### Financial potential and business expectations

Zelensky directly named the scale of the expected investments: "The potential — billions of euros and mutual growth." The address to business representatives at the summit and the mention of "promising projects and agreements" indicate that a portfolio of specific initiatives has already been formed within the framework of C8. For Ukraine, which is in the process of preparing for EU accession, such a regional format creates an additional channel of economic integration that does not depend exclusively on bilateral negotiations with Brussels.
