Saudi Arabia and South Korea signed an energy memorandum of understanding in Riyadh on Sunday covering cooperation in crude oil, natural gas, refining, and petrochemicals, with artificial intelligence, digital transformation, and stockpile expansion folded into the same bilateral instrument. The Saudi Energy Ministry’s announcement of the MoU names the signatories as Saudi Minister of Energy Prince Abdulaziz bin Salman and South Korean Minister of Trade, Industry and Energy Kim Jung-kwan.
The Saudi-Korea energy partnership, as both governments now frame it, is no longer a string of one-off project deals. It is a written framework covering stockpiles, pipelines, digital tools, and the way the two countries move crude through increasingly contested sea lanes. The MoU followed a two-day visit by Kim, who arrived in Riyadh on Saturday and was scheduled to head to Qatar on Monday and the United Arab Emirates on Tuesday, per the Korean Ministry of Trade, Industry and Energy. That trip itself is a follow-up to a Middle East swing in April by a special envoy delegation sent by South Korean President Lee Jae-myung.
What Was Signed in Riyadh
Kim and Prince Abdulaziz met at the Energy Ministry in Riyadh on Sunday for talks on energy investment and cooperation, according to the Saudi Gazette. Signed at the end of the meeting and immediately published in the Saudi Energy Ministry’s announcement, the MoU is the central output. Per the Saudi Gazette and Korea Herald reporting, the agreement commits the two sides to cooperation in:
- Petroleum, natural gas, and their derivatives
- Refining and petrochemicals
- Energy-related investment partnerships, including expanded Saudi crude storage in the Korean Strategic Petroleum Reserve
- Crude oil pipeline infrastructure linking production and export facilities
- Artificial intelligence and digital technologies in the energy industry
- Research and development, sustainability, and energy infrastructure development
The six cooperation areas each anchor a different workstream. Among them, stockpiles, pipelines, and AI had not appeared as named MoU commitments between the two countries before this signing.
What makes the document consequential is the breadth. By tying stockpiles, pipelines, and digital tools to a single bilateral instrument, the MoU is a renewable framework that both governments can keep adding projects to. The stockpile expansion sits at the front of that pipeline.
From Crude Cooperation to Industrial Partnership
Kim did not stop with the energy minister. He also met with Saudi Investment Minister Fahad Al-Saif and Industry and Mineral Resources Minister Bandar Al-Khorayef to review the progress of South Korean companies’ projects in the kingdom, per the Korea Herald. Two flagship industrial projects were on the table at those bilateral meetings. The Asia Business Daily reported that both sides also agreed to advance cooperation in the mineral sector.
Saudi resources including sulfur, phosphate rock, bauxite, and rare earth elements would be linked to Korean refining and processing technologies under the mineral sector agreement, with both governments setting up a cooperative foundation between research institutions for mineral exploration and the development of national geological information. South Korean firms have been working Saudi clean-energy deals for years, including Gaoncell’s fuel cell showcase in Riyadh.
With facilities capable of producing 50,000 electric and internal combustion vehicles annually, the Hyundai Motor and Saudi Public Investment Fund joint venture plant is aiming to begin mass production next year. The International Maritime Industries shipyard, a joint venture between HD Hyundai Heavy Industries and Aramco, covers 4.96 million square meters, the largest shipyard in the Middle East, and plans to build approximately 40 very large crude carriers and other vessels each year. Through S-Oil, Saudi Aramco has built the Shaheen petrochemical complex in Ulsan around a thermal crude-to-chemicals facility and a steam cracker. The MoU is the framework that holds the existing project pipeline together.
The mineral and clean-energy provisions give the MoU its industrial reach. Although none of those projects were signed on Sunday, all of them get their bilateral cover from the framework.
Why the Trip Came Now: A Red Sea Reroute in the Making
The MoU was signed against a backdrop that is reshaping the global oil trade. After U.S.-Israeli strikes on Iran in late February, South Korea, which depends heavily on imports from the Middle East for its energy supply, is contending with the closure of the Strait of Hormuz. Oil prices have surged since those strikes, putting growth and inflation under pressure in Seoul, the Korea Herald reported. In April, Saudi Arabia pledged to give top priority to crude oil and naphtha shipments to South Korea during a Middle East tour by a special envoy delegation sent by South Korean President Lee Jae-myung. Kim’s own framing of the deal puts the same point more bluntly.
Amid lingering instability in global supply chains, we have secured a stable supply of key resources, such as crude oil and naphtha, and established a foundation for long-term cooperation in the energy sector with Saudi Arabia.
Kim said it in a release issued by the Korean Ministry of Trade, Industry and Energy after the signing in Riyadh. In a separate radio interview on Red Sea supply routes, the minister said Saudi Arabia has promised to prioritize Korean oil shipments, and Seoul is preparing to dispatch five Korean-flagged vessels to the Saudi port of Yanbu on the Red Sea coast. The government is considering escort operations by the Cheonghae unit’s Dae Joyoung destroyer, Kim said.
Korea’s Storage Network Is Now the Bilateral Backbone
The MoU is one piece of a wider stockpiling offer Korea is putting in front of Gulf producers. State-run Korea National Oil Corp. leases idle storage capacity to foreign producers under a joint stockpiling program, generating rental income while securing priority rights to purchase the stored oil during supply disruptions. Since the Hormuz disruption, Gulf producers have accelerated that shift toward Korean storage, with multiple Middle Eastern oil producers approaching Seoul to store crude in Korea. Saudi crude now gets priority access to that expanding capacity under the agreement.
| Cooperation Area | Specific Commitment in the MoU |
|---|---|
| Crude stockpiling | Expand Saudi crude storage in the Korean Strategic Petroleum Reserve |
| Pipeline infrastructure | Explore projects for crude pipelines linking production and export facilities |
| AI and digital transformation | Use AI and digital technologies to drive innovation in the energy industry |
| Petrochemicals and refining | Joint work on petroleum, gas, derivatives, refining, and petrochemicals |
Korea stores roughly 10 million barrels of foreign crude under existing joint agreements, including 4 million barrels for Kuwait Export Crude and 4 million barrels of light sour grades from Abu Dhabi National Oil Co. That network gives Korea an edge when negotiating with Gulf producers. Under the MoU, Saudi crude now gets that same priority access.
KNOC’s rundown of its nine stockpiling bases puts the country’s total storage capacity at 146 million barrels, with current reserves of 100 million barrels. The country holds about 100.1 million barrels of government-controlled reserves, fifth largest among IEA members.
The Korean Companies Already at Work in Saudi Arabia
The MoU is the diplomatic frame, and the companies execute the deals underneath it. Hyundai Motor and the Saudi Public Investment Fund are pushing a local manufacturing plant toward mass production next year, with capacity for 50,000 electric and internal combustion vehicles annually. Spanning 4.96 million square meters, the HD Hyundai Heavy Industries and Aramco joint shipyard at IMI is the largest in the Middle East, with plans for approximately 40 VLCCs and other vessels a year. Per Hydrocarbon Processing, the $7 billion Shaheen petrochemical complex in Ulsan is the largest single foreign investment in a single Korean venture, where Saudi Aramco, the largest shareholder in S-Oil, has built a thermal crude-to-chemicals facility and a steam cracker.
The MoU’s petrochemical and refining language is the bilateral cover for those investment flows. Both governments can now extend the framework to other project areas, including advanced industries, on the same bilateral terms. Per Hydrocarbon Processing, Saudi Aramco holds a 63.4% stake in S-Oil.
The Crude Math Already Shifting
The numbers behind the MoU are already moving on their own. South Korea released 22.46 million barrels of strategic oil reserves on March 12 as part of an IEA emergency action to contain international oil prices after the U.S.-Israeli attacks on Iran, the Korea Herald and Aju Press reported.
- 100.1 million barrels: Korean government-controlled strategic reserves
- 5th largest: Korea’s ranking among IEA members by reserves
- 146 million barrels: Total KNOC capacity across nine stockpiling bases
- 22.46 million barrels: Korea’s contribution to the March 2026 IEA emergency release
Saudi Arabia accounts for the largest share of April shipments, with stockpile swap volumes at around 32 million barrels. The MoU formalizes that priority-access arrangement for the rest of the year. With Kim’s Doha and Abu Dhabi stops ahead, the next round of bilateral deal flow is being set up in the same visit.
The trip is not over. Kim is scheduled to visit Qatar on Monday and the United Arab Emirates on Tuesday to discuss cooperation in crude oil and gas supply chains, and collaboration in the nuclear power, plant, and new industry sectors.
