US Economic Diplomacy With Allies Becomes an Election Showcase for Trump

Investment pledges by Japan and South Korea make tempting achievements for Trump to hold up ahead of the voting.

U.S. Senator Dan Sullivan (blue tie) speaks while standing next to U.S. President Donald Trump during an event announcing new investment for the Alaska LNG pipeline, Sep. 30, 2026.

On September 28, Trump invited Iowa Representative Ashley Hinson, the Republican running for an open Senate seat, to the Oval Office to announce a new $15 billion steel plant in her home state, which is being built by the local subsidiary of an Indian conglomerate. Two days later, with Alaska Senator Dan Sullivan standing beside him, Trump announced roughly $54 billion in prospective South Korean investment in the Alaska LNG pipeline. 

Notably, both announcements came a little over a month before the midterm elections. The Associated Press noted that it was “the second time in three days” Trump had paired a major investment announcement with a Republican Senate candidate in a race that had become unexpectedly competitive.

Seoul described the Alaska announcement quite differently. South Korean Industry Minister Kim Jung-kwan said it went “far beyond what was agreed,” while his ministry said it had not decided whether to invest or how much. The U.S. Commerce Department’s fact sheet was more conditional: the two sides had agreed to begin work on Alaska LNG, subject to commercial reasonableness and domestic legal requirements. 

Similarly, Washington also presented a roughly $22 billion Texas project and a nuclear framework valued at up to $120 billion. Again, Seoul has indicated a more cautious approach to those investments, with individual reactor projects still under review. In other words, the headline figures may not all materialize. 

The election wasn’t the driving force behind these projects or negotiations, which have been in the works for nearly a year. But the announcements have clear electoral value. On September 30, Trump said he had done “a very bad job of explaining how good the country is doing.” The Iowa and Alaska events show how investment announcements involving U.S. partners are being caught up in Trump’s pre-election economic messaging. 

The approaching elections – and polling suggesting that a number of Republican seats in Congress are at risk – increases the political value of presenting long-term allied investment plans as immediate economic wins. Both South Korea and Japan had agreed to invest hundreds of billions of dollars in the United States as part of overall economic deals reached in 2025 with the Trump administration. The upcoming election may be impacting the announcement of specific projects under those investment pledges – although it’s hard to establish the connection definitively. It’s also possible that Japan and South Korea could use Trump’s sense of urgency over specific projects to leverage better terms. 

The structure of the deals is responsible for some of the confusion. The Korean and Japanese “agreements” are actually administrative arrangements that create no legally binding obligations. Under the standard timetable, actual funding is not required until at least........
