IVANO-FRANKIVSK / BUKOVEL, Ukraine – In the rolling foothills of the Carpathian Mountains, far from the front lines of Russia’s ongoing war of aggression, Ukrainian President Volodymyr Zelenskyy this week formally launched a new regional cooperation format that Kyiv hopes will reshape trade, energy and security relations across Central and Eastern Europe. The inaugural summit of the “Carpathian Eight,” or C8, brought together leaders and representatives from Ukraine and seven neighbouring countries – Romania, Serbia, Poland, Slovakia, the Czech Republic, Austria and Hungary – along with the European Union, in a deliberate effort to turn the Carpathian region into a more cohesive economic and security space.
The three-day gathering, held primarily in the western Ukrainian resort town of Bukovel and surrounding areas of Ivano-Frankivsk Oblast from 18 to 20 September 2026, produced more than 50 investment and trade agreements valued at over €1 billion, with energy projects accounting for the majority. Zelenskyy framed the initiative as both a practical response to the disruptions caused by Russia’s full-scale invasion in 2022 and a longer-term strategic play to accelerate Ukraine’s European integration while strengthening the resilience of the entire region.
“This marks the start of a movement that should bring our countries even closer together and create another strong framework for cooperation at the EU level,” Zelenskyy said in remarks following the opening sessions. He thanked regional partners for keeping critical trade and transport corridors open since the invasion, noting that the Carpathians had already proven themselves a vital logistical backbone for Ukraine’s wartime economy. Security, he stressed, remained the overriding priority “right now and for the years ahead.”
The Carpathian Eight is not a formal military alliance or a substitute for NATO or EU membership. Instead, it is designed as a flexible platform linking national governments, regional administrations, businesses and local communities. Its declared focus areas include energy resilience, logistics and transport interconnectivity, cross-border economic cooperation, critical minerals, military mobility and support for local communities. Organisers presented a joint investment portfolio of roughly 90 to 95 projects with a combined estimated value ranging from €9.4 billion to more than €40 billion, depending on the scope of projects included. Energy accounted for the largest share, with dozens of initiatives in solar, wind, storage, interconnectors and gas infrastructure.
Among the concrete proposals highlighted by Zelenskyy was a Carpathian wind-energy cluster with a planned capacity of 1.5 gigawatts. “Solar and wind energy. Energy storage. And new interconnectors. And our large underground gas storage facilities,” he said. “The Carpathians can become an energy contributor to the European Union – and not only a transit region.” The Ukrainian president repeatedly linked the initiative to Europe’s broader goal of reducing dependence on Russian energy supplies, a theme that has dominated regional politics since the 2022 invasion and the subsequent energy crisis.
High-level attendance underscored the political weight Kyiv attached to the launch. Polish Prime Minister Donald Tusk, Serbian President Aleksandar Vučić and Romanian President Nicușor Dan were among the most prominent guests. Representatives from Slovakia, the Czech Republic, Austria and Hungary also took part, as did EU officials. The presence of Vučić was particularly notable given Serbia’s historically complex relationship with both Russia and the West; his participation signalled Belgrade’s willingness to engage in pragmatic regional economic formats even while maintaining its own careful balancing act.
Participants adopted a declaration of intent establishing the Carpathian Integration Initiative as a coordinating platform. The document commits the countries to annual summits and to joint work on energy infrastructure, civil protection systems, transport corridors and the gradual alignment of candidate countries with the EU acquis. It emphasises strengthening good-neighbourly relations, economic interconnectivity and sustainable development within the shared European space. Officials described the C8 as a potential building block toward a formal EU macro-regional strategy for the Carpathians, sometimes referred to in discussions as EUSCARP.
Energy at the centre
Energy cooperation dominated both the political messaging and the business programme. More than half of the agreements prepared for signature concerned renewable power generation, storage and related infrastructure. Ukraine’s extensive underground gas storage facilities – among the largest in Europe – were repeatedly cited as a strategic asset that could serve the wider region once interconnectors and market mechanisms are strengthened. Zelenskyy argued that turning the Carpathians into a net energy exporter rather than a mere transit zone would simultaneously bolster Ukraine’s reconstruction, generate revenue and contribute to continental energy security.
The timing is deliberate. Russia’s systematic attacks on Ukrainian energy infrastructure since 2022 have forced Kyiv to accelerate decentralisation, renewable deployment and integration with European grids. Neighbouring countries have themselves sought alternatives to Russian pipeline gas and electricity imports. Joint projects in the Carpathians offer a geographically coherent way to expand capacity while improving physical and market connections. Summit materials listed dozens of specific energy proposals, including wind and solar parks, battery storage, grid modernisation and cross-border transmission lines. Business representatives – nearly 550 were expected – examined these projects in an “Investment Lab” format designed to match developers with capital.
Ukrainian officials noted that 55 of the projects, valued at around €8 billion, were located in the Ukrainian Carpathians alone. Broader regional portfolios pushed the total higher. While many of the €1 billion in near-term agreements remain subject to final negotiation and financing, the political signal was clear: Kyiv intends to use the Carpathian platform to lock in concrete commercial commitments rather than merely declarative statements of support.
Trade, logistics and reconstruction
Beyond energy, the summit placed heavy emphasis on transport and logistics. The Carpathian region has long functioned as a critical east-west and north-south corridor. Since 2022, it has absorbed diverted trade flows after Russian control of Ukraine’s Black Sea ports and the disruption of traditional routes. Zelenskyy highlighted the need for better roads, railways, border infrastructure and ports, arguing that improved connectivity would strengthen both economic resilience and collective security. “Security always depends on our ability to work together – when our systems are connected, and our countries cooperate, our protection is stronger too,” he said.
Officials also positioned the Carpathians as a potential European gateway for routes from the South Caucasus and Asia via the Black Sea. This vision aligns with longer-standing efforts to develop the Middle Corridor and alternative supply chains that reduce reliance on Russian territory. Joint work on critical minerals, industrial projects and agricultural value chains featured in the investment pipeline as well. Ukrainian Prime Minister Serhii Koretskyi later described three priority directions for the C8: expanding mutual trade and investment, attracting major international capital through joint regional platforms, and involving the partner countries in Ukraine’s reconstruction as a shared economic project.
The business programme reflected these ambitions. Deals spanned oil and gas, energy, infrastructure and culture. While precise breakdowns of the €1 billion-plus package were not released in full, Ukrainian officials stressed that implementation would be the next test. “The next step is to move ahead with implementation,” Koretskyi wrote after the summit. Zelenskyy publicly thanked leaders, businesses and local communities for their engagement, expressing hope that the potential measured in billions of euros would translate into tangible growth.
Security dimension
Although the Carpathian Eight is primarily economic in character, security considerations permeated the discussions. Zelenskyy described the Carpathian macro-region as “one of the most reliable foundations of our defence.” The format is intended to enhance military mobility, civil protection systems and preparedness for emergencies. Improved infrastructure and energy interconnections are themselves framed as contributions to collective resilience. During the summit, Polish Prime Minister Tusk announced that Poland had joined an anti-ballistic missile coalition involving Ukraine and other partners, illustrating how bilateral and minilateral security arrangements continue to evolve alongside the new regional format.
The C8 does not replace existing mechanisms such as the Ukraine Defence Contact Group, the Coalition of the Willing or bilateral security agreements. Rather, it adds a geographic layer focused on the immediate neighbourhood that has borne much of the logistical and refugee burden of the war. By institutionalising regular high-level meetings and project pipelines, Kyiv hopes to lock in practical cooperation that outlasts any single political cycle in the participating capitals.
Context and challenges
The launch of the Carpathian Eight occurs against a complex regional backdrop. Relations between Ukraine and some neighbours have experienced friction in recent years, particularly over agricultural trade, historical issues and the pace of EU accession. Poland, long one of Ukraine’s strongest supporters, has seen periods of tension, yet Polish businesses have continued to expand their presence in the Ukrainian market. Hungary’s government under Viktor Orbán has maintained a more ambivalent stance toward both the war and Ukraine’s EU path. Serbia occupies a unique position as a non-EU, non-NATO country with significant economic ties to both Russia and the West. The decision of these governments to send high-level representatives or engage constructively was therefore politically significant.
For Ukraine, the initiative serves multiple purposes simultaneously. It demonstrates to European partners that Kyiv is capable of generating regional public goods rather than solely requesting assistance. It creates additional channels for investment at a time when reconstruction needs remain enormous. It reinforces the argument that Ukraine’s integration strengthens the wider European project rather than diluting it. And it offers a concrete response to the energy and logistics vulnerabilities exposed by the war.
Sceptics will note that previous regional formats in Central and Eastern Europe have sometimes struggled to move from summit declarations to sustained delivery. Financing the larger project pipeline will require significant private capital as well as public and international financial institution support. Political alignment among the eight participants is not automatic; differing national priorities and external relationships will test the format’s cohesion. Implementation capacity inside Ukraine, still under wartime conditions, remains a constraint. The declaration of intent and the €1 billion in near-term agreements represent a start rather than a finished architecture.
Nevertheless, the political optics of the Bukovel summit were carefully managed. Hosting the inaugural meeting on Ukrainian soil, in a region that has become synonymous with wartime resilience and logistical ingenuity, sent a message of agency. The emphasis on renewable energy and interconnectors aligned the C8 with the European Green Deal and REPowerEU objectives. The inclusion of both EU members and non-members, plus the EU institutions themselves, positioned the format as complementary to rather than competitive with existing European structures.
Looking ahead
Zelenskyy and his team have signalled that the Carpathian Eight is intended as an enduring platform with annual summits. The immediate test will be whether the agreements signed or prepared in September 2026 move into active project development and whether the joint investment portfolio attracts the scale of capital required. Success would mean measurable progress on wind and solar capacity, stronger electricity and gas interconnections, upgraded border and transport infrastructure, and deeper commercial ties across the region.
For Ukraine, the initiative is one more strand in a broader strategy of diversification – of energy sources, trade routes, security partnerships and diplomatic formats. For its Central and Eastern European neighbours, it offers a structured way to engage with a large neighbouring market that is simultaneously a security challenge, a reconstruction opportunity and a future EU member. Whether the Carpathian Eight evolves into a durable engine of regional integration or remains a series of well-intentioned summits will depend on the follow-through in the months and years ahead.
As the first summit concluded, Zelenskyy returned to a consistent theme: the strength that comes from connected systems and cooperating countries. In the Carpathians this week, Ukraine sought to turn that principle into concrete partnerships on trade, energy and security. The region, and Europe more broadly, will now watch to see how far the new format can travel.
