The accelerating global transition toward renewable energy is fundamentally reshaping international economic relations and creating new forms of cooperation between resource-rich countries and technologically advanced economies. As governments pursue carbon neutrality, strengthen energy security, and diversify energy supply chains, renewable energy has become an increasingly important pillar of foreign policy, economic diplomacy, and regional connectivity. Within this evolving landscape, Azerbaijan and China are gradually emerging as strategic partners in the green energy sector, driven by complementary economic interests and converging long-term development strategies. For Azerbaijan, cooperation with China supports the country's objective of diversifying its hydrocarbon-dependent economy while transforming itself into a regional hub for renewable energy production, green industrial development, and electricity exports. For China, deeper engagement with Azerbaijan strengthens its presence in the South Caucasus, reinforces the Belt and Road Initiative (BRI), and expands opportunities for Chinese companies to participate in overseas renewable energy markets while advancing Beijing's global leadership in clean energy technologies.

Political relations between the two countries have provided an increasingly favorable foundation for expanding green energy cooperation. Azerbaijan and China established diplomatic relations on 2 April 1992, and over the following three decades bilateral cooperation expanded steadily in trade, infrastructure, transportation, and economic development. A significant milestone occurred on 27 September 2022, when President Ilham Aliyev and President Xi Jinping met on the sidelines of the Shanghai Cooperation Organisation (SCO) Summit in Samarkand. The two leaders discussed strengthening cooperation in transport, logistics, trade, investment, and energy, while reaffirming their commitment to expanding bilateral strategic cooperation. These discussions laid important political groundwork for the rapid expansion of renewable energy cooperation that followed over the next two years.

An even more consequential breakthrough came on 3 July 2024, during the SCO Summit in Astana, where Presidents Ilham Aliyev and Xi Jinping signed the Joint Declaration on the Establishment of a Strategic Partnership between the Republic of Azerbaijan and the People's Republic of China. The declaration elevated bilateral relations to the level of a strategic partnership and identified green development, renewable energy, climate cooperation, and low-carbon technologies among the priority areas of future cooperation. The two governments expressed their readiness to deepen cooperation in clean energy, energy storage, new energy vehicles, electricity transmission, energy conservation, emissions reduction, and other green technologies while encouraging enterprises from both countries to participate actively in renewable energy investment projects. The declaration also confirmed China's support for Azerbaijan's chairmanship of COP29 and both countries' commitment to promoting international cooperation in addressing climate change.

Azerbaijan's own energy strategy has undergone a profound transformation during the past decade. While hydrocarbons remain the foundation of the national economy through the Azeri–Chirag–Gunashli (ACG) oil fields and the Shah Deniz gas field, Baku has increasingly adopted policies aimed at diversifying its energy portfolio and reducing dependence on fossil-fuel-based electricity generation. The adoption of the Law on the Use of Renewable Energy Sources in Electricity Production in May 2019 established Azerbaijan's first comprehensive legal framework governing renewable energy investment, introducing competitive procurement mechanisms, investment guarantees, and transparent regulatory procedures designed to attract international developers. This legislation represented a strategic shift in national policy by positioning renewable energy not merely as an environmental initiative but as a central pillar of long-term economic diversification, industrial modernization, and sustainable development.

The pace of Azerbaijan's green transition accelerated significantly after the Second Karabakh War in 2020, when the government announced its intention to transform the liberated territories of Karabakh and East Zangezur into Green Energy Zones. These regions possess considerable solar, wind, and hydropower potential and have become central to Azerbaijan's long-term renewable energy strategy. The initiative seeks to integrate renewable electricity generation with smart cities, digital infrastructure, sustainable transport, and environmentally friendly industrial development, making the liberated territories laboratories for Azerbaijan's green transformation.

Azerbaijan's renewable resource base provides strong justification for this ambitious strategy. According to official estimates, the country possesses approximately 27 GW of economically viable onshore renewable energy potential, while the Azerbaijani sector of the Caspian Sea contains an estimated 157 GW of offshore wind potential. Rather than replacing hydrocarbons, these renewable resources are intended to complement Azerbaijan's traditional energy exports by supplying domestic electricity demand, thereby allowing larger volumes of natural gas to be exported to regional and European markets. Consequently, Azerbaijan increasingly views renewable energy as an instrument for strengthening both energy security and geopolitical influence while positioning itself as a future exporter of green electricity and, eventually, green hydrogen.

Institutional reforms further accelerated this transition. On 3 February 2023, Azerbaijan hosted the First Green Energy Advisory Council Ministerial Meeting alongside the Ninth Southern Gas Corridor Advisory Council, creating a new multilateral platform dedicated to renewable energy cooperation, electricity interconnections, offshore wind, hydrogen, and sustainable investment. The establishment of the Green Energy Advisory Council symbolized Azerbaijan's commitment to complementing its role as a reliable natural gas supplier with an expanding position within the international renewable energy sector. In January 2024, SOCAR established SOCAR Green, a specialized subsidiary responsible for renewable energy development, green hydrogen initiatives, and international cooperation in sustainable energy technologies.

Another landmark development occurred when President Ilham Aliyev declared 2024 the "Green World Solidarity Year" through a presidential decree issued on 25 December 2023. The initiative emphasized renewable energy, climate resilience, environmental sustainability, and international cooperation as national priorities while preparing Azerbaijan to host the 29th United Nations Climate Change Conference (COP29) in Baku from 11 to 22 November 2024. Hosting COP29 substantially enhanced Azerbaijan's international profile as an emerging renewable energy hub and created new opportunities for cooperation with technologically advanced countries, including China.

China enters this partnership from a position of exceptional technological strength. Over the past two decades, Beijing has become the world's largest producer of renewable energy equipment and one of the leading investors in clean energy infrastructure. Chinese companies dominate global supply chains for solar photovoltaic modules, wind turbines, lithium-ion batteries, electric vehicles, and electricity storage systems. At the same time, China's commitment to achieving peak carbon emissions before 2030 and carbon neutrality before 2060 has accelerated technological innovation across renewable energy industries. Through the Belt and Road Initiative, Chinese enterprises have increasingly expanded overseas investments in renewable energy, electricity transmission, smart grids, and sustainable infrastructure, making cooperation with strategically located countries such as Azerbaijan increasingly attractive.

The establishment of the Azerbaijan–China Strategic Partnership in July 2024 significantly accelerated practical cooperation. During COP29, held in Baku in November 2024, Azerbaijan signed a series of agreements with major Chinese renewable energy companies, transforming political commitments into concrete investment projects. On 14 November 2024, the Ministry of Energy of Azerbaijan signed an Implementation Agreement with China Energy Overseas Investment Co., Ltd. and SOCAR Green LLC for the development of a 160 MW solar power plant in Fuzuli, one of Azerbaijan's Green Energy Zones. On the same day, the Ministry also signed a broader Memorandum of Understanding with China Energy on renewable energy cooperation and another MoU with China Datang Overseas Investment Co., Ltd. covering investment in renewable energy projects, feasibility studies, and the establishment of a Renewable Energy Research and Development Center in Azerbaijan.

Cooperation expanded further on 18 November 2024, when Azerbaijan signed additional Memoranda of Understanding with PowerChina Resources Limited and TBEA Co., Ltd. During meetings with Energy Minister Parviz Shahbazov, executives of both companies discussed investment opportunities in solar and wind power, engineering, construction, project operation, and the export of green electricity. The parties emphasized that renewable energy cooperation had become one of the principal pillars of the newly established Azerbaijan–China Strategic Partnership and explored opportunities for Chinese participation in Azerbaijan's ambitious plans to develop large-scale renewable energy capacity and regional electricity exports.

Only two days later, on 20 November 2024, Azerbaijan deepened cooperation by signing another Memorandum of Understanding with China Southern Power Grid International (Hong Kong) Co., Ltd. and PowerChina Huadong Engineering Corporation Limited. This agreement focused on strategically important technologies including battery energy storage systems (BESS), pumped hydro storage, high-voltage direct current (HVDC) transmission, and the digitalization of electricity transmission and distribution networks. These technologies are essential for integrating intermittent renewable energy into Azerbaijan's electricity system while supporting future exports of green electricity through regional transmission corridors.

The momentum generated during COP29 continued into April 2025, when President Ilham Aliyev paid a state visit to China. During the visit, Azerbaijan and several leading Chinese companies signed an extensive package of renewable energy agreements. These included an investment agreement for the 100 MW Gobustan Solar Power Plant, implementation agreements covering offshore wind development, a 100 MW floating solar power plant with a 30 MW battery energy storage system on Lake Boyukshor, a 160 MW solar power project with PowerChina Resources, and a Memorandum of Understanding with China's Electric Power Planning and Engineering Institute concerning renewable energy planning and electricity system development. Particularly significant was the signing of a Memorandum on developing a 2 GW offshore wind energy project in the Azerbaijani sector of the Caspian Sea involving SOCAR Green, China Datang Overseas Investment, and PowerChina Resources.

These agreements demonstrate that bilateral cooperation has evolved beyond conventional investment toward comprehensive collaboration encompassing renewable electricity generation, offshore wind, battery storage, electricity system planning, research and development, and advanced energy technologies. Chinese companies are no longer viewed solely as contractors but increasingly as long-term strategic partners capable of contributing to Azerbaijan's broader industrial modernization and technological transformation.

The emerging partnership also possesses an important geopolitical dimension. Azerbaijan occupies a strategic position along the Middle Corridor, connecting China with Europe through Central Asia, the Caspian Sea, the South Caucasus, and Türkiye. As China continues expanding the Belt and Road Initiative, renewable energy infrastructure can complement transport connectivity by supporting the decarbonization of logistics hubs, industrial parks, ports, and railway systems. Investments in electricity transmission, digital energy management, and battery storage can strengthen both the efficiency and sustainability of Eurasian transport corridors, creating synergies between green energy development and regional connectivity.

At the same time, Azerbaijan's ambition to become a regional exporter of renewable electricity creates new opportunities for cooperation with China in cross-border electricity infrastructure. The development of projects such as the Black Sea Submarine Electricity Cable, regional electricity interconnectors, and future green hydrogen initiatives could benefit from Chinese expertise in transmission technologies, energy storage, and smart grid systems. Such cooperation would reinforce Azerbaijan's position as both an energy producer and an emerging regional electricity hub.

Despite these promising developments, several challenges remain. Large-scale renewable energy deployment requires continued regulatory reforms, modernization of transmission infrastructure, expanded private-sector participation, and long-term investment certainty. Azerbaijan must continue strengthening its legal and institutional framework while ensuring that renewable energy projects remain economically competitive and technologically sustainable. Moreover, increasing geopolitical competition across Eurasia requires Baku to maintain a balanced foreign policy that enables cooperation with China while preserving productive partnerships with the European Union, Türkiye, the Gulf states, Japan, South Korea, and other international investors.

Nevertheless, the trajectory of bilateral relations suggests that renewable energy will become an increasingly important pillar of the Azerbaijan–China Strategic Partnership. By combining Azerbaijan's abundant renewable resources and strategic geographic position with China's technological leadership, manufacturing capacity, and financial capabilities, both countries are well-positioned to contribute to the emergence of a more sustainable, interconnected, and resilient Eurasian energy system. As the global transition toward low-carbon development accelerates, Azerbaijan–China cooperation in renewable energy is likely to extend beyond individual projects toward broader collaboration in green industrial development, electricity connectivity, advanced energy technologies, and regional climate cooperation, reinforcing the Caspian region's growing role in the global green economy.
