Introduction

The global transition to clean energy is not merely a climatic imperative; it is a competitive and destiny-shaping arena for the reconfiguration of the geo-economic map of power, the fate of which is determined on the tables of supply chains and mineral fields. In this equation, China dominates the solar energy supply chain by an extraordinary margin. According to data from the China Photovoltaic Industry Association, in 2024, China produced approximately 93% of the world’s polysilicon, 96% of its wafers, 92% of its photovoltaic cells, and 86% of its photovoltaic modules. Simultaneously, by producing about 75% of the world’s lithium-ion batteries and dominating advanced solar cell technologies, the country has redefined the architecture of the clean technology supply chain. This dominance is the product of decades of Chinese government investment in strategic industries and targeted subsidies, placing the West in a position of dependency. On the other hand, Saudi Arabia, as the world’s largest oil exporter, stands at the intersection of two imperatives: on one side, it faces the need for economic diversification for a post-oil era; on the other, it must maintain internal cohesion through rent distribution. The difference in today’s approach compared to the past lies not in discarding the logic of rent but in shifting its material base; the origin of rent is moving from underground hydrocarbon resources to industrial production facilities, and from raw material exports to controlling the links of the technological value chain. At this confluence, Saudi Arabia deploys its capital on the path of transitioning from oil, while Beijing, by regulating the flow of technology, plays an effective role in reshaping the region’s energy structure. The Middle Eastern market could play a bridging role in the future between China’s economy and other regions in the field of clean energy.

Institutional Architecture: The Confluence of Belt and Road and Vision 2030

The development of macro-economic cooperation on the scale of infrastructure projects, above all, requires a robust institutional framework to reduce “transaction costs” and mitigate systemic risks. In the economic relations between China and Saudi Arabia, this institutional architecture has taken shape in the form of the strategic alignment of the “Belt and Road Initiative” and “Vision 2030.” These overarching documents are not merely ceremonial memoranda of understanding, but rather create a practical mechanism for reducing negotiation costs, investment risks, and potential disputes between the parties. The “Comprehensive Strategic Partnership Agreement” and the memorandum of understanding for cooperation in the field of green hydrogen have also provided a legal framework for joint investments, with governmental guarantees for capital transfer, tax exemptions, and intellectual property protection. In line with this goal, the Saudi Public Investment Fund (PIF), serving as the financial arm of this convergence, has invested approximately $10 billion in joint projects with Chinese companies such as JinkoSolar. Thus, the institutional framework resulting from the strategic alignment of the two countries has reduced transaction costs and provided an operational foundation for transforming complementary advantages of capital and technology into tangible cooperation.

A Secure Market: The Geo-economic Function of Saudi Arabia in Diversifying China’s Export Destinations

European and American markets, due to their size, high purchasing power, and historical depth, remain vital destinations for China’s export industries. However, the trade environment with the West has been fraught with severe volatility in recent years. For instance, during the US-China trade war, tariff rates on Chinese goods rose to as high as 145%. Of course, these decisions, often adopted through executive orders without sustainable legal backing, quickly became unstable and disruptive. Amidst this, the enduring reality is the structure of “Section 301 tariffs.” For example, the tariff rate on solar cells imported from China was raised to 50%, and solar wafers were also added to this tariff list at the same rate. The subtle yet decisive point, however, is the granting of strategic exemptions to 14 items of Chinese solar cell manufacturing equipment (such as silicon growth furnaces and diamond wire saws). This exemption demonstrates that tariffs are not merely a punitive policy but also a tool for managing real supply chain dependencies—a domain where the West still has no choice but to accept China’s dominance, especially in this field. In such an environment, Saudi Arabia emerges as a secure market. Although the size of this market is relatively small, it offers tariff-free access and relative stability. Unlike the bureaucratic and multi-layered Western systems that prolong the project approval process and expose it to changes, the centralized structure of power in Riyadh enables rapid decision-making with maximum executive authority at the highest level. This governance model, which sharply reduces transaction costs and risks arising from political uncertainty, holds double appeal for Chinese investors seeking predictability and speed of execution. Furthermore, the Middle East could serve as a bridge for China to access other regional markets in the future.

From Commodity Trade to Managed Localization: Limitations and Realities of Technology Transfer

The pattern of interaction between Beijing and Riyadh in the field of renewable energy has moved beyond the phase of mere import-export and entered the stage of joint industrial investment. However, a precise analysis of this process reveals a strategy of managed localization on China’s part. By establishing wind turbine and solar panel manufacturing plants in Saudi Arabia’s free zones, Chinese companies have transferred the energy-intensive segments and final assembly links of the supply chain to Riyadh. The recent agreement between the two sides to build a polysilicon production plant in Saudi Arabia’s new industrial cities is a step toward deepening this chain, as Saudi Arabia, with its access to cheap energy, possesses a high comparative advantage for producing this key raw material. The outcome of these arrangements is a division of labor that inserts Riyadh into the middle, repetitive links of the value chain. However, even this level of cooperation can be highly valuable as a starting point on Saudi Arabia’s path to industrialization. It may not qualify as genuine knowledge transfer, at least in the short term, but it is undeniably a starting point—one that, in previous cooperation models, countries dependent on the West were generally deprived of.

Saudi Arabia’s Domestic Political Economy: Post-Oil Functions, Rent Redistribution, and Elite Survival

The development of clean energy industries in Saudi Arabia goes beyond climate goals; it is a vital tool in the domestic political economy for elite survival and the redefinition of the social contract under Vision 2030. In this post-oil transition, the Saudi sovereign wealth fund acts as a distributor of new rent resources, linking a network of technocrats to the core of power. In this context, government revenues are directly channeled into financing major economic and infrastructure projects. Since oil is not an endless source of income, the ruling strategy is that, in the long run, the profitability of these very projects will replace the finite oil rent and provide new material foundations for sustaining the legitimacy of the political system. In this equation, Chinese technology is not merely an economic variable; it is a strategic catalyst for ensuring political stability and the continued hegemony of the ruling elite.

Conclusion

The relations between Beijing and Riyadh in the energy transition domain—beyond a commercial interaction yet far from a comprehensive political alliance—reflect a strategic convergence in international political economy. In this new architecture, the two countries, with a realistic understanding of each other’s structural needs, have formed a network of institutionalized cooperation. By adopting a strategy of managed localization, China has not only turned Riyadh into a secure market and regional export hub but has also deepened its uncontested hegemony over the architecture of the clean technology supply chain. In this structure, China maintains its position as the exclusive architect of the technology flow and the controller of the fundamental links of value. On the other hand, the Saudi government, by pragmatically accepting this technological hegemony, has secured a key tool to manage its post-oil transition. Integration into the middle links of China’s value chain allows Riyadh to successfully redefine the material foundations of rent in its domestic political economy. This new articulation ensures the continuity of the social contract and the long-term legitimacy of the ruling elite. Ultimately, the Chinese sun over Riyadh is a symbol of an evolving geo-economic order—an order in which Saudi Arabia, in the role of investor and relying on its financial capacities, strives to guarantee its systemic survival in the post-oil era. However, the scales ultimately tip in favor of Beijing’s broader goals, leading to the quiet yet profound consolidation of China’s strategic hegemony in the geo-economic coordinates of the Persian Gulf.
