Tensions in the US-China bilateral trade relationship have been a significant driver of investment in the clean energy sector in third countries, reshaping clean energy supply chains linked to both Chinese and US firms.
Third countries have positioned themselves to seize opportunities related to US-China strategic competition around clean energy and critical minerals, but this strategy carries risks that have grown more pronounced with recent shifts in US trade policy.
US policymakers seeking to build alternatives to China-exclusive supply chains could encourage the White House to clarify the meaning of recent official statements relating to transshipment and duty evasion, and establish country-specific tariff-rate quotas on clean energy exports from jurisdictions with significant levels of Chinese investment.
The global clean energy economy today looks starkly different than it did even 10 years ago. Not only have production and deployment of clean energy technologies expanded significantly, the geographic distribution of clean energy manufacturers, resellers, and end-users has shifted dramatically. In 2015, clean energy supply chains were somewhat diversified.[i] Today, China is by far the largest producer of most of the intermediary and finished goods that feed into global solar, wind, battery, and electric vehicle (EV) supply chains—in many cases accounting for a majority of global production.[ii] (See Figure 1).
Note: *US data for 2022 and 2024 are estimated from EIA growth numbers and Comtrade data and should be taken as purely illustrative.
These tectonic shifts in a sector poised to become one of the principal engines of global economic growth have occurred against deteriorating US-China relations and are causing growing concern among US leaders about the US-China bilateral trade deficit. Minimizing the flow of Chinese or Chinese-affiliated clean energy products into US markets has become a bipartisan project, with major implications for both global energy supply chains and the clean energy transition for the United States and China.
But the impact of US trade hawkishness is not limited to the bilateral relationship. Third countries that serve as nodes along clean energy supply chains have been significantly affected by US-China trade tensions. In some cases, these third countries have benefited economically from a diversification of Chinese and US investment and supply chains. Yet growing US concerns about tariff circumvention and the Trump administration’s mercurial approach to tariffs have injected uncertainty into the durability of those investment and supply chain relationships, and left countries with ties to both Chinese and US markets feeling squeezed.
This commentary examines how instability in US-China trade ties is shaping investment and trade in clean energy goods around the world and assesses the implications of China’s growing energy engagement in third countries for US policymakers.
Benefits to Third Countries
Expanded Chinese-Global South Trade
Since the Obama administration, the United States has steadily increased market barriers on a range of Chinese clean energy goods, substantially decreasing the short-term cost competitiveness of those goods and, in some cases, reducing import volumes to a trickle. In response, Chinese manufacturers have recalibrated their commercial strategies to focus on more receptive markets, increasing supply, lowering prices, and accelerating clean energy adoption.
Between 2021 and 2024, emerging markets accounted for 70% of the growth in China’s export of solar, wind, and EV products. In 2024, nearly half of these exports went to the Global South, matching exports to developed countries.[iii] This influx has helped lower clean energy prices and transform energy systems in many developing economies, especially those without significant domestic clean energy industries.[iv] For example, Pakistan, one of the largest Asian importers of Chinese solar panels, imported enough in 2024 to expand its power capacity by one-third. In Africa, too, cheap solar panels are helping countries lessen their reliance on hydropower following the worst mid-season drought in more than a century.[v]
Trade and Investment Partnerships
China has reinforced its shift to non-US markets through trade agreements and policy initiatives. Participation in frameworks like the Regional Comprehensive Economic Partnership (RCEP) has reduced barriers to trade in clean energy technologies and energy-efficient appliances to Southeast Asia.[vi] Since 2021, renewable energy investment has also become a new policy focus of China’s Belt and Road Initiative (BRI).[vii] In the first half of 2025, BRI green energy engagement reached US$9.7 billion across wind, solar, and waste-to-energy projects—an increase of US$4.2 billion from 2024—adding an estimated 11.9 gigawatts (GW) of green energy.[viii]
Amid ongoing US-China trade tensions, both advanced and emerging economies are positioning themselves as reliable partners for Chinese clean-tech investment. European OECD members now constitute the largest destination for China’s exports and overseas manufacturing investments by value (not without consequences to European producers, as discussed below).[ix] Meanwhile, a number of resource-rich countries in the Global South are angling to be strategic players in the global clean energy transition by pursuing policies that not only attract upstream (raw goods) but also midstream (processing and refining) investment that build local manufacturing capacity as a means to break out of extractive economic relationships.
Indonesia, for example, has leveraged its vast nickel reserves, a key input into EV batteries, by banning raw ore exports and requiring local processing, drawing major Chinese investment into smelting and battery precursor production.[x] Officials in other mineral-rich countries are likely to seek to replicate Indonesia’s success in shifting Chinese investment strategy away from raw mineral exports to local minerals processing. For example, South Africa, which produces about 70% of global platinum-group metals and has vast manganese, vanadium, and chromium reserves, is prioritizing local value-add through its 2025 Critical Mineral Strategy, with China as a likely partner.[xi]
Alongside this surge in Chinese exports and investment, US-backed financing is expanding as Washington seeks to counterbalance Beijing’s influence and mitigate Beijing’s chokehold on critical materials. Through the International Development Finance Corporation, the US has provided a US$150 million loan for Mozambique’s Balama graphite mine[xii] and helped broker an agreement between the Democratic Republic of Congo and Zambia to develop an EV battery supply chain tapping their cobalt and nickel reserves.[xiii] More recently, the Trump administration announced a multi-billion dollar partnership with Australia to reduce US dependence on Chinese exports of rare earth materials following Beijing’s imposition of stringent export controls on them in response to US tariffs in October.[xiv]
Supplying the US Market
While the Biden administration steadily increased market barriers on Chinese imports and expanded US-backed financing, it also created (now largely obsolete) incentives for the adoption of clean energy technologies alongside new supply chain relationships to meet growing American demand for these products. Such initiatives included the Inflation Reduction Act’s clean energy investment and production tax credits, and rebates on EVs.
Pairing trade barriers on China with subsidies for clean energy generation and low-carbon technologies created lucrative market opportunities for clean energy firms in some third countries, particularly in the solar sector. Exporters based in Southeast Asia currently account for more than 90 percent of imports of solar products into the United States,[xv] despite being dwarfed by Chinese solar manufacturing and exports at a global level.
With respect to lithium batteries, Korea and Japan have become the second and third largest suppliers to the United States, although China continues to dominate.[xvi] Finally, although foreign-made EVs remain a small share of total sales in the United States, prohibitive tariffs on Chinese EVs mean that non-Chinese producers will not have to compete with low-cost Chinese brands.
Deepening Risks
The benefits described above come with associated risks and liabilities that have grown more pronounced since the start of the second Trump administration.
Price Competition
An influx of low-cost Chinese solar panels, batteries, and EVs—widely attributed to overproduction and associated surplus capacity in China’s domestic market—threatens to undercut domestic manufacturing capabilities in many importing countries, undermining their long-term industrial development and contributing to premature deindustrialization.[xvii]
Countries that aim to build local clean-tech industries have struggled to compete with China’s scale-driven cost advantages. As of 2024, Chinese automakers accounted for one in four EVs sold in Europe, with prices roughly 20% below European models.[xviii] In Thailand, Chinese brands now hold over 70% of the EV market.[xix] Governments from Bangkok to Brussels are responding with tariffs, anti-subsidy investigations, and incentives to protect domestic industry.[xx]
Chinese Foreign Ownership
Another risk is growing dependence on Chinese clean energy equipment and financing, which creates structural and strategic vulnerabilities beyond trade relations. Between 2023 and 2024, China announced US$58 billion in overseas clean energy manufacturing projects, along with US$24 billion in overseas power generation and storage deals, largely in South Asia, the Middle East, and North Africa.[xxi] The sheer scale of these investments and export volumes has increased the risk of supply chain disruptions for importing countries and raised concerns about exposure to Chinese retaliatory measures and economic coercion.
Consider the challenge now facing Indonesia. Jakarta’s efforts to promote investment into value-added activities in its nickel sector have come with a cost: Chinese companies now dominate the sector, controlling an estimated 75% of domestic nickel operations.[xxii] During the Biden administration, Indonesia sought to diversify its partnerships and was considering limits on future Chinese project ownership to comply with US trade rules. These efforts to rebalance its supply chain partnerships are now facing major headwinds with the partial repeal of the IRA.[xxiii]
Dwindling US Opportunities
Similarly, the opportunities many third countries identified in the US market are beginning to look illusory. The recent omnibus reconciliation bill repealed or significantly curtailed many of the most important tax credits under the IRA and substantially expanded the scope of the “foreign entities of concern” restrictions on subsidy eligibility.[xxiv] These changes will inevitably suppress demand for imported clean energy products and undercut the commercial logic of additional investment into US renewable power generation and EV supply chains.
Compounding these challenges, the Trump administration’s assertive use of tariffs has cast a pall around US-focused export strategies in third countries. Steep tariffs on countries angling to compete with China as global manufacturing powerhouses have led multinational firms to pause and reconsider their plans to shift production out of China.[xxv] To add to the uncertainty, multiple US courts have found that the legal basis the White House has invoked for most of these tariffs, the International Emergency Economic Powers Act (IEEPA), is invalid.[xxvi] The tariffs remain in force for the time being, with final resolution likely to come with a decision from the US Supreme Court, expected in early November.
Perhaps the biggest whipsaw has been for countries that benefited from Chinese investment into their domestic manufacturing sectors that, in turn, supplied US firms. In July 2025, the White House issued an executive order adjusting previous tariffs imposed under IEEPA, which included a declaration that “goods transshipped to evade applicable duties [i.e., tariffs]” would be subject to a 40% tariff.[xxvii] Neither “transshipment” nor “duty evasion” are terms with clear legal meaning under IEEPA or other trade and customs authorities, and could conceivably encompass a broad range of practices.[xxviii] US political trade “deals” with Cambodia, Malaysia, Thailand, and Vietnam announced in October all reference cooperation on “duty evasion” but do not clarify how such evasion should be assessed or what rules of origin would apply to goods shipped from those four countries.[xxix]
Southeast Asian countries that import Chinese components and re-export will be particularly exposed to this new transshipment policy, but the impacts will likely be felt more broadly. The Malaysian solar industry, which drew billions in Chinese investment during the first Trump administration only to crater in the wake of Biden administration tariffs, offers a worrying precedent for regional actors in this regard.[xxx]
Policy Implications
For US policymakers seeking a high degree of decoupling from Chinese-linked clean energy supply chains—or to limit deployment of clean energy technologies in general—the current state of affairs may be desirable. Chinese and third country exporters of clean energy supply chains are likely to pull back from supplying the US market in the face of uncertainty over tariffs and subsidies, leading to slower deployment of clean energy infrastructure in the United States and higher prices for clean energy goods. But dwindling points of entry for Chinese firms into US-bound supply chains are likely to accelerate Chinese investment and trade partnerships outside North America, potentially undercutting US efforts to blunt China’s influence in the Global South.[xxxi]
If policymakers’ goal is to replace Chinese and Chinese-linked clean energy supply chains with alternatives from third countries, current US policy is counterproductive. As of this writing, many third countries face actual or prospective economywide tariffs similar to and even higher than those on Chinese goods, making it difficult for them to compete on price.[xxxii] Rather than seeking partnerships with aspiring clean energy manufacturing hubs like India and Brazil, for example, the administration has imposed a baseline tariff of 50% on both countries’ exports under IEEPA, relative to China’s 30% (current as of October 29, 2025).[xxxiii] To exacerbate matters, the administration has justified its IEEPA tariffs on non-Chinese imports with shifting rationales, making it difficult for exporters to feel confident in the stability of current tariff rates and leaving trading partners uncertain about what measures, if any, they could adopt to receive more favorable treatment.
US policymakers interested in building alternatives to Chinese-exclusive clean energy supply chains could encourage the White House to clearly define the scope of the transshipment-related tariff policy authorized in President Trump’s executive order. They could also go a step further and propose linking actual or threatened imposition of those tariffs to tightened rules of origin on implicated goods, which third country governments could leverage to demand Chinese investment lead to more value-added activity, upskilling, and technology transfer, similar to what Indonesia achieved in its nickel sector.
A second, complementary approach would be to agree to tariff-rate quotas on specific clean energy goods on a country-by-country basis, similar to what was achieved with textiles under the (now defunct) Multi-Fibre Agreement.[xxxiv] Under this scheme, third countries would have reliable low-tariff access to the United States only up to a mutually agreed upon quantity of goods, allowing the US to control the geographic distribution of clean energy imports and discouraging Chinese investors from cycling from one country to another to avoid US anti-circumvention and anti-transshipment measures.
Rather than antagonizing longstanding trade partners with high tariffs, Washington’s strategic interests may be better served by coordinating with select third countries on addressing the extreme concentration of global clean energy supply chains. The goal of such coordination would be twofold: building resilience to future disruptions and shocks by diversifying sources of key clean energy goods and ensuring future clean energy investment does not flow disproportionately to Chinese firms at the expense of other market players.

[xxviii] Transshipment, which generally refers to the routing of goods through intermediate destinations, is extremely common in global supply chains and has numerous legitimate commercial applications. Tariff evasion, meanwhile, could plausibly refer not only to clearly illegal acts like smuggling and fraudulent customs declarations but also more ambiguous scenarios such as disputes over whether a good originates from a particular country under applicable rules of origin.
