Trump Presses Japan and South Korea to Back Alaska LNG as Investment Pledges Fall Behind Target
Tokyo has deployed just $36 billion of a $550 billion US investment commitment, with Washington adding Alaska pipeline equity to an already stretched list of demands.
Trump told South Korean President Lee Jae Myung at the White House in late August (2026-08-25) that Washington and Seoul would be "making a deal, a joint venture" on an Alaska LNG pipeline, renewing a push he had already raised with Japan, Aju Press reported. Both Seoul and Tokyo have already committed hundreds of billions of dollars to US investment to preserve market access. The Alaska demand implies those commitments are not a ceiling.4
Tokyo agreed to a $550 billion US investment program whose terms Washington controls, and whose financial beneficiary may be the White House itself rather than the broader US economy, Foreign Policy reported. The deal was structured to protect Japanese automakers after Trump imposed 25% automobile tariffs in April (2026-04).3,1
But executing the pledge is harder than making it. The first tranche totaled $36 billion, and a second round of $73 billion is pending. With the straightforward deals already done, Foreign Policy reported it is unlikely Japan could meet the $550 billion figure by the November 2028 deadline — a timeline Tokyo is tracking closely.3
South Korea followed a parallel path. Seoul agreed to invest $350 billion in the United States, equivalent to roughly 19% of South Korea's entire GDP in 2024, The Economist reported. Neither government found a viable way to push back. Washington is extracting commitments from allies who cannot afford to be seen as unreliable by the United States or as weakened in the eyes of Beijing.2,1
Trump announced reciprocal tariffs of 24% on all Japanese goods and 25% on all Korean goods, then suspended both for 90 days, The Economist reported. Suspensions are revocable. That lever staying in place, rather than the tariff itself, is what keeps both governments at the table.1
The IMF put numbers on the damage on April 22 (2026-04-22): South Korea's 2026 growth forecast cut to 1%, down from 2% in January; Japan's fell 0.5 percentage points in the same revision. Japan and South Korea together represent the largest block of LNG import demand in the world, and lower growth in both economies reduces spot volumes over time.1
JKM Asian LNG front-month held at $26.05/MMBtu on Wednesday (2026-09-23). USD/JPY was at 157.69 on the same day, lifting the yen cost of each imported LNG cargo above where it stood at the start of the tariff cycle. That currency drag compounds the financial cost of the Washington relationship for Tokyo's buyers. [live prices]
Alaska LNG, if it moves forward with Japanese or Korean equity and long-term offtake, would lock both governments into dollar-denominated supply contracts on terms not yet disclosed. On the existing $550 billion program, Trump "calls the shots" on investment direction, Foreign Policy reported; the same logic applied to a pipeline deal would mean energy security becomes contingent on White House approval at each stage.3,4
Japan has deployed $36 billion, has $73 billion pending, and needs to find another $441 billion before November 2028. Whether Alaska LNG investment counts toward that total, or arrives as a separate ask on top of it, is not yet clear. That distinction matters more to Tokyo's planners right now than the pipeline's long-term commercial merits.3
