South Korea plans to reduce the Middle East's share of its crude oil imports to 50% by 2035, according to a Reuters report, a move aimed at widening the country's supplier base for its refinery-heavy economy.

Reuters reported on September 23, 2026 that South Korea plans to cut its reliance on Middle East crude oil imports to 50% by 2035. The goal is framed as a share of total crude purchases rather than an absolute volume, meaning Middle Eastern barrels would account for no more than half of the crude the country buys at that point. Because the policy is described as a reduction, it implies the current share sits above that 50% threshold. The report did not specify interim milestones, the volume of crude involved, or which suppliers would take up the displaced barrels.
South Korea produces essentially no crude oil of its own, so its refining industry runs almost entirely on imported barrels. Middle Eastern producers, with Saudi Arabia traditionally among the largest, have been natural suppliers because of shipping proximity, established long-term supply arrangements and the compatibility of their crude grades with Korean refinery configurations. South Korea is also a significant exporter of refined products, which means the composition and cost of its crude slate feed directly into what its refineries can sell into Asian and other export markets. That dual role as importer and product exporter shapes how quickly the crude mix can be changed.
Candidates to replace Middle Eastern volumes include crude from the United States, Latin American producers such as Brazil and Guyana, and suppliers in Africa and Southeast Asia. Each option carries trade-offs: voyages from the U.S. Gulf Coast to Northeast Asia are considerably longer than Gulf-to-Korea routes, requiring different tanker sizes and tying up more capital in transit inventory. Crude quality is a second constraint, since refineries configured to process medium, higher-sulfur grades may need operational adjustments or capital investment to run lighter, sweeter barrels efficiently. Pricing benchmarks differ as well, with Middle Eastern grades typically linked to Dubai-linked pricing while Atlantic Basin crudes reference Brent or WTI.
Diversifying import sources is a longstanding energy-security objective for economies that depend heavily on seaborne crude. Concentrating purchases in one region exposes an importer to supply disruptions, particularly around chokepoints such as the Strait of Hormuz, through which a large share of the world's seaborne oil passes. Other major Asian importers have pursued comparable diversification strategies over the past two decades, though the pace has varied with price spreads, freight economics and contract availability. South Korea additionally maintains strategic petroleum reserves and long-term supply arrangements that complement supplier diversification.
According to a Reuters report dated September 23, 2026, South Korea plans to reduce its reliance on Middle East crude oil imports to 50% by 2035. The target is expressed as a share of the country's total crude imports, so Middle Eastern barrels would make up no more than half of purchases by that date. Since the measure is described as a cut, it indicates the current proportion is above 50%.
South Korea has virtually no domestic oil production, so its refineries depend entirely on imported crude. Middle Eastern suppliers have historically been competitive because of shorter shipping distances, established long-term contracts and crude grades that match the configuration of Korean refineries. That combination made the region the default source for a large share of the country's crude slate.
Analysts commonly point to the United States, Brazil, Guyana, and producers in Africa and Southeast Asia as potential alternative sources. However, each carries trade-offs, including longer voyage distances from the Atlantic Basin, different freight and tanker requirements, and crude quality that may not match existing refinery configurations. Benchmark pricing also differs, with Atlantic Basin crudes generally linked to Brent or WTI rather than Dubai-linked pricing.

Several practical questions remain unanswered in the initial report, including whether the 50% figure covers crude only or also refined products and condensate. It is also unclear how the target would be enforced, given that most of South Korea's refining capacity is operated by private companies that make procurement decisions on commercial grounds. Achieving a national sourcing target would likely require alignment between government policy and corporate purchasing, potentially through term contracts, equity stakes in overseas fields, or incentives tied to supply agreements. The report did not detail the policy instruments or the government bodies responsible for delivery. Based on public news sources.
Concentrating crude purchases in a single region leaves an importing economy exposed to supply disruptions, particularly around maritime chokepoints such as the Strait of Hormuz. Diversifying suppliers is a standard risk-management approach used by major Asian importers, and it complements other tools such as strategic petroleum reserves and long-term supply contracts. South Korea's plan fits that broader pattern of reducing single-region exposure.
If the target is met, it would gradually shift a meaningful volume of Northeast Asian crude purchasing toward Atlantic Basin, African and Southeast Asian suppliers, which could alter tanker routes and term-contract structures over time. The scale of any shift depends on how much of the plan is actually implemented, since most Korean refining capacity is privately operated and procurement decisions are commercially driven. The original report did not specify volumes or interim milestones.
