South Korea and the United States have agreed to move ahead with a liquefied natural gas-fired combined cycle power plant in Encinal, Texas, and U.S. nuclear power projects as strategic investments in the U.S. The Alaska LNG project was added to the investment list, but while Washington publicly stated that South Korea would invest more than $50 billion, Seoul says it will negotiate further over the size and details of the commitment. MASGA, or Make American Shipbuilding Great Again, a $150 billion shipbuilding cooperation project between the two countries, is expected to become the next focus of bilateral talks.
U.S. President Donald Trump announced the terms of the strategic investment agreement from the Oval Office at the White House in Washington on the 30th. The announcement came nine days after the South Korean government reported its plan for U.S. projects to the National Assembly on the 22nd. Authority to declare the investment projects rests with the U.S. president, so the agreement becomes official only when Trump announces it.
Seoul secured several safeguards in the talks. The two sides agreed to write into a legally binding operating contract a clause ensuring that the previously agreed strategic investment total of $200 billion and the annual remittance ceiling of $20 billion are not exceeded. The provision is designed to keep the overall remittance burden from growing even if costs for individual projects rise. The two sides also agreed to split profits from all projects evenly until the full principal and interest on the investment are recovered, strengthening the risk-pooling function.
That framework is seen as the reason the U.S. government, departing from what had been reported earlier, pinned down South Korea's Alaska LNG investment and put a specific figure on it of "more than $50 billion." The $22.3 billion for the Encinal LNG combined cycle plant in Texas and the $120 billion needed for eight large nuclear reactors already account for $142.3 billion in confirmed investment, leaving $57.7 billion under the cap. In effect, Washington is pressing Seoul to pour nearly all of the remaining room into the Alaska LNG project. The project is estimated to require more than $67 billion at most.
The government says it will approach the Alaska LNG investment cautiously. Industry and Trade Minister Kim Jung-kwan told reporters on the 22nd, after reporting on the U.S. investments to the National Assembly, that "if we accept the costs as they are, we could exceed the cap, so we asked the U.S. to scale down the Alaska LNG project and present it again." He added, "We will argue fiercely so that it is commercially acceptable and strategically serves our interests."
The Alaska LNG project is an infrastructure venture that would build a 1,300-kilometer gas pipeline linking the North Slope oil fields in the north to Nikiski on the southern coast, along with a liquefaction terminal for exports. It is considered difficult to build because workers are hard to find in a sparsely populated region and a large pipeline must be laid across polar terrain with unstable ground. Industry officials have warned that commercial viability will be hard to secure unless LNG prices surge.
To improve the commercial case if the project proceeds, the U.S. agreed to offer South Korea a range of benefits. These include creating favorable conditions for South Korean equipment suppliers and cutting tariffs on equipment that includes steel and other materials. Washington will also guarantee South Korea priority access to LNG produced in Alaska by signing long-term purchase contracts on economically viable terms. The Ministry of Trade and Industry also sees various incentives offered at the Alaska state level as factors that would improve the project's viability.
If commercial viability is secured, the ministry calculates, the Alaska LNG project could help diversify an LNG supply chain that now depends on a handful of key shipping routes. Qatari cargoes must pass through the Strait of Hormuz, Australian and Malaysian cargoes through the South China Sea and the Taiwan Strait, and U.S. cargoes through the Panama Canal, concentrating routes at major maritime chokepoints. Alaskan cargoes, by contrast, would cross the open western Pacific, with almost no risk of blockage. Kim also said, "Looking at our current LNG import routes, they are vulnerable overall. So there is a need to review alternative import routes strategically."
Investment in supply chain security, including critical minerals, is expected to follow the Alaska LNG project. "If even $1 billion to $2 billion of room is left under the cap, I would like to add meaningful projects that serve both countries' strategic interests, such as critical minerals, even if they are small in scale," Kim said. The aim is to identify projects that maximize the strategic interests of both countries even if profitability is somewhat lower.
With much of the $200 billion in U.S. investment now agreed, analysts expect MASGA negotiations to begin in earnest. Discussions on MASGA, worth $150 billion, did not advance in the latest round of talks. At issue is whether simple order volumes or ship financing count toward the MASGA investment total, and how deeply South Korean companies must be involved in reviving U.S. shipyards. "One round of talks on U.S. investment is now finished, and the next round is MASGA," Kim said. President Lee Jae-myung also said that cooperation in shipbuilding, including warship construction, was a main agenda item at a surprise summit with the U.S. held in New York on the 24th.
Trump's announcement came nine days after the government reported the terms to the National Assembly. That was an unexpected outcome, given that Washington had been pressing Seoul to invest quickly. Analysts attribute the delay to internal U.S. procedures, which slowed as major diplomatic events, including the U.N. General Assembly and Chinese President Xi Jinping's state visit to the U.S., overlapped just as South Korea's procedures were completed.
A memorandum of understanding on U.S. investment signed by the two countries last year states that "the president of the United States holds final decision-making authority over the investments." Before making a final selection, however, Trump must receive project recommendations from an investment committee chaired by Commerce Secretary Howard Lutnick. That committee must consult with South Korea either directly or through a consultation committee chaired by Kim. In other words, even after the government completes domestic procedures with its report to the National Assembly, the U.S. investment projects are finalized only after administrative steps on the American side.
