US–Serbia Strategic Dialogue Advances Energy, 5G and Infrastructure Cooperation

The first US–Serbia Strategic Dialogue in Washington on 17 July 2026 established a new framework for cooperation between Belgrade and Washington, with energy infrastructure, telecommunications, security, science and technology among the main areas of discussion.

Led by US Secretary of State Marco Rubio and Serbian Foreign Minister Marko Đurić, the meeting produced several initiatives with potential economic implications, including a memorandum on energy infrastructure and regional energy security, preliminary American support for the Đerdap III pumped-storage hydropower project, and a proposed $50 million US Export-Import Bank loan guarantee for Telekom Srbija’s 5G deployment.

The agreements remain at different stages of development, with most representing memorandums, preliminary decisions or financing announcements rather than completed investment contracts. Their economic impact will depend on procurement processes, ownership structures, environmental approvals, financing conditions and implementation requirements.

Energy cooperation places Đerdap III at the centre of bilateral agenda

The energy component of the dialogue highlights Đerdap III, also known as Iron Gate III, as one of the largest potential infrastructure projects linked to the new partnership. The planned pumped-storage hydropower facility on the Danube River has been discussed since the Yugoslav period but has not reached a final investment decision. Current concepts envisage a large storage facility capable of absorbing excess electricity and supplying power during periods of higher demand.

Serbian energy models have examined possible configurations ranging from approximately 600 MW to 2.4 GW, although the final capacity, reservoir design and operating model have not been determined. A potential completion timeline around 2038 has been mentioned, indicating that the project remains in an early development phase.

The Ministry of Mining and Energy has begun activities related to a preliminary feasibility study, spatial planning and environmental assessment. Serbia has also created an information-sharing framework with Romania, whose cooperation will be required due to the Danube’s cross-border status, the existing jointly managed Đerdap hydropower complex, and potential effects on regional electricity and water systems.

Interest from six US companies has provided an initial indication of market attention, but it does not represent contractual commitments. Before financing can be secured, Đerdap III will require a defined technical concept, environmental and water-management approvals, a grid connection assessment, a dispatch model and a clear revenue structure.

Pumped-storage facilities generate value through electricity price differences, using lower-cost electricity for pumping and selling electricity during higher-demand periods. Additional revenues can come from balancing services, reserves, congestion management and system restoration. The project’s economic case is therefore linked to electricity market volatility and the growth of variable renewable energy sources rather than only hydrological conditions.

Storage capacity linked to Serbia’s renewable expansion plans

The importance of Đerdap III is increasing as Serbia develops new wind and solar capacity while continuing to operate an ageing lignite-based power generation fleet. Additional renewable generation is expected to create periods of surplus electricity production, including possible low or negative prices, followed by periods when flexible electricity supply is limited. A large-scale storage facility could help absorb excess generation and reduce reliance on imported electricity during peak demand.

The project could also strengthen Serbia’s role in regional electricity balancing and trading between central Europe and the southern Balkans. Its potential commercial impact would involve Elektroprivreda Srbije (EPS), the transmission system operator EMS, Romanian partners and regional electricity markets.

However, a multi-gigawatt pumped-storage project would represent one of Serbia’s largest infrastructure investments. No final capital expenditure estimate, financing structure or public-private risk allocation model has been disclosed. The eventual investment value will depend on civil engineering works, tunnels, reservoirs, electromechanical equipment, transmission upgrades, geological conditions and environmental mitigation measures. Long construction periods would expose the project to inflation, financing costs during construction and potential delays. The engineering and procurement model will therefore be a key factor in determining project economics.

Gas diversification becomes a strategic energy priority

The strategic dialogue also addressed Serbia’s gas supply position, with diversification away from heavy dependence on Russian gas emerging as a key issue. Serbia continues to rely significantly on Russian gas supplies, while shorter-term contracts and geopolitical uncertainty have increased the importance of alternative sources.

The Serbia–Bulgaria gas interconnector provides access to the wider Southern Gas Corridor and the Greek LNG network. The Alexandroupolis LNG terminal creates additional potential access to US and other international LNG supplies, while further cooperation with Romania could provide another supply route. US LNG is not expected to replace Russian gas solely through price competition. The commercial consideration is the value of supply security and contractual flexibility.

Diversification may increase average supply costs during some periods, but it reduces exposure to interruptions from a single supplier and strengthens Serbia’s negotiating position. Reliable gas access remains important for industrial companies, district heating systems and electricity generation, affecting production costs, inflation pressures and government intervention risks.

NIS ownership remains unresolved amid sanctions pressure

The future ownership structure of Naftna Industrija Srbije (NIS) remains one of the most immediate economic issues connected with US policy.

NIS operates the Pančevo refinery, with annual processing capacity of approximately 4.8 million tonnes, and supplies most of Serbia’s fuel market. Russian companies hold the controlling stake, while the Serbian state owns just under 30%.

The US Treasury’s Office of Foreign Assets Control (OFAC) has issued temporary licences allowing NIS operations to continue while discussions over ownership changes proceed. A new waiver allows crude imports and operations until 28 August 2026, extending the period for negotiations over the possible acquisition of the Russian-held stake by MOL Group.

The temporary licences have prevented immediate disruption to fuel supplies, but they have not resolved the long-term uncertainty. Banks, insurers, crude suppliers, pipeline operators and trading partners cannot treat repeated regulatory extensions as equivalent to a permanent ownership solution.

The uncertainty increases compliance costs and affects NIS planning for procurement, financing and capital expenditure. The strategic dialogue provides a channel for discussions between Belgrade and Washington, but it does not remove OFAC requirements. Any long-term solution must result in a transaction that changes control and meets sanctions-related conditions.

Telekom Srbija receives proposed EXIM-backed 5G financing

The most clearly quantified financial commitment from the dialogue is the proposed $50 million EXIM loan guarantee for Telekom Srbija Group. The financing is intended to support the company’s 5G network deployment using suppliers considered trusted by Washington. Although the amount represents only part of the cost of a nationwide mobile network, the initiative has broader strategic importance because 5G infrastructure supports industrial systems, transport, utilities, public services and defence-related applications.

Supplier selection affects equipment costs, cybersecurity architecture, software maintenance, data governance and long-term technology dependencies. The EXIM guarantee could reduce financing costs and support competition from US and allied suppliers against Chinese vendors that often combine equipment supply with financing and rapid deployment models.

For Telekom Srbija, the facility could diversify its financing sources and improve access to export-credit-supported equipment purchases. The final value of the arrangement will depend on pricing, procurement requirements, currency exposure and repayment structures. The financing also relates to commitments made under the 2020 Washington Agreement, under which Serbia agreed to restrict equipment from “untrusted vendors” in 5G networks.

US technology cooperation intersects with Chinese investment presence

China remains one of Serbia’s largest sources of infrastructure and industrial investment, with Chinese companies active in mining, metals, transport, energy and telecommunications. Serbia and China maintain a comprehensive strategic partnership, including cooperation in artificial intelligence and technology governance.

American financing in telecommunications and digital infrastructure therefore creates broader decisions concerning technology standards, cloud systems, artificial intelligence, surveillance infrastructure and data centres. Competition among US, European and Chinese suppliers could improve commercial conditions, but differences between technology ecosystems may create challenges if infrastructure standards become fragmented.

Defence, science and Expo cooperation expand bilateral engagement

The United States and Serbia also agreed to strengthen defence cooperation, building on the 20-year partnership between the Serbian Armed Forces and the Ohio National Guard. Serbia has requested the purchase of US defence equipment, although no equipment list or contract value has been announced.

The cooperation would add to Serbia’s mixed defence inventory, which includes domestic production, Russian, Chinese and western systems. New US equipment would require consideration of training, maintenance, spare parts, software updates and interoperability requirements. Serbia’s military neutrality does not prevent purchases from the United States, but Washington will continue assessing end use, technology security and Serbia’s wider defence relationships.

The two countries also continued humanitarian cooperation, including $1.5 million allocated for demining activities addressing unexploded ordnance. Serbia’s participation in the Artemis Accords adds a science and technology dimension to the relationship, supporting principles for peaceful civil space exploration and potential cooperation in areas such as satellite applications, geospatial services, agriculture and environmental monitoring. The expanded Fulbright Programme includes a Serbian commitment of $300,000 annually under a cost-sharing agreement aimed at increasing academic exchanges.

Investment relations depend on project execution

US participation in Expo 2027 Belgrade provides an additional platform for American companies to examine opportunities in Serbia and the wider Western Balkans. The event may attract interest from technology, infrastructure and consumer companies, although long-term economic impact will depend on whether companies establish operations, partnerships, supply agreements or regional service centres after the exhibition.

Serbia also plans to open consulates in San Francisco and Miami to strengthen links with US technology companies, investors and diaspora capital. San Francisco provides access to technology, venture finance and artificial intelligence sectors, while Miami offers connections in finance, logistics, real estate and technology.

Serbia recorded €3.5 billion in foreign direct investment in 2025, equal to approximately 3.9% of GDP, although inflows were 33.5% lower than the record level achieved in 2024. European and Chinese investors remain more visible in major physical assets, leaving room for increased US participation. American companies typically require predictable procurement procedures, enforceable contracts, transparent state aid rules and reliable legal protection before committing capital.

Strategic dialogue linked to EU accession requirements

The new US framework also intersects with Serbia’s EU accession process, as the European Union remains Serbia’s largest trade and investment partner. EU regulations will continue shaping Serbia’s product standards, energy policies, environmental rules and competition framework.

Cooperation with Washington and alignment with Brussels are not necessarily conflicting, particularly in areas such as energy diversification, secure telecommunications, regional stability and transparent infrastructure procurement. Differences between US and EU approaches, as well as Serbia’s balancing between external partners, could create challenges. The unresolved relationship with Russia remains particularly significant because of NIS ownership, gas dependence and foreign-policy issues.

Chinese investment presents a different challenge, as Chinese companies are deeply integrated into Serbia’s mining, steel, transport and telecommunications sectors.

The strategic dialogue provides Serbia with additional sources of financing, technology and political support, but its economic value will depend on completed projects, transparent risk allocation and the ability to reduce dependency risks. The future of Đerdap III, the implementation of the Telekom Srbija 5G financing, and the resolution of the NIS ownership issue will be among the key indicators of whether the new framework produces long-term economic outcomes.
