US-South Korea Nuclear Talks Focus on Uranium Enrichment Rights

South Korea and the US continued security talks for a second day in Seoul, focusing on Seoul's bid to secure uranium enrichment and spent nuclear fuel reprocessing rights for civilian purposes. The talks aim to revise the 2015 bilateral nuclear energy cooperation pact that currently bars Seoul from these activities without US consent. The US delegation, led by Under Secretary of State Allison Hooker, also discussed the nuclear-powered submarine program and broader economic security issues. The follow-up talks were delayed due to legislative processes and concerns over treatment of US e-commerce giant Coupang in South Korea.

South Korea, US continue security talks for second day with uranium enrichment rights in focus

Seoul, June 3

South Korea and the United States continued talks on their security agreements for a second day Wednesday, with Seoul's bid to secure uranium enrichment and spent nuclear fuel reprocessing capabilities for peaceful purposes expected to top the agenda.

Wednesday's talks marked the second and final day of a meeting that began Tuesday as the allies launched bilateral consultations to advance the agreements reached at an October summit between the leaders of the two countries last year.

Under the joint fact sheet, the US committed to supporting processes that will lead to uranium enrichment and spent nuclear fuel reprocessing for civilian use and Seoul's push to build conventionally armed nuclear-propelled submarines, Yonhap News Agency reported.

The US delegation, led by Under Secretary of State for Political Affairs Allison Hooker, arrived in Seoul on Monday for the talks.

Also accompanying her on the trip were Ivan Kanapathy, senior director for Asia at the National Security Council (NSC), and Matthew Napoli, deputy administrator for defense nuclear nonproliferation at the National Nuclear Security Administration, among other officials.

On Wednesday, the talks were expected to center on the issue of allowing Seoul to enrich uranium and reprocess spent nuclear fuel for civilian purposes, a process that would require a revision of a 2015 bilateral nuclear energy cooperation pact.

The existing agreement bars South Korea from enriching uranium or reprocessing spent nuclear fuel unless it obtains US consent through consultations and in writing.

Seoul is reportedly seeking to revise the pact, known as the 123 Agreement, in a way that would help secure "advance consent" from the US -- a preapproved and long-term permission.

Working-level discussions on these issues were expected to be the focus of Wednesday's meeting, with officials from South Korea's National Security Office and the NSC likely to lead the talks.

The allies discussed the nuclear-powered submarine program Tuesday.

In a social media post Wednesday, Hooker said she "discussed working closely to make progress on bilateral nuclear cooperation" during her meeting with National Security Adviser Wi Sung-lac on Tuesday.

"We also covered a wide range of issues that underscored economic security is national security," she said on X.

The follow-up security talks took place months later than expected as Seoul's legislative process for a planned USD 350 billion investment in the US -- another key element of the summit agreement -- had been delayed.

Growing US concerns over what Washington views as discriminatory treatment of US-listed e-commerce giant Coupang Inc. in South Korea have also been cited as factors behind slow progress in the security talks.

As someone from the US, I'm a bit uneasy about this. Uranium enrichment, even for civilian use, is a slippery slope. But then again, if India can be trusted with it, why can't South Korea? The geopolitical dynamics in Northeast Asia are already tense enough.

South Korea has been a responsible player in nuclear non-proliferation. They have strict safeguards and IAEA oversight. If they want enrichment for energy security, let them have it. The world needs more clean energy options, especially in Asia where demand is high. 🇮🇳👍

The 123 Agreement revision is a big deal. South Korea's nuclear industry is world-class, but they're hamstrung by Cold War-era rules. Meanwhile, North Korea does whatever it wants with its program. The US needs to be consistent in its approach to allies vs adversaries.

South Korea building nuclear submarines? That changes the naval balance in the region entirely. China and North Korea won't be happy. India should watch this closely, given our own submarine ambitions. The 'conventionally armed' part is key, but still a major capability upgrade.

A respectful criticism: The US dragging its feet on this because of commercial disputes with Coupang is petty. National security cooperation shouldn't be held hostage to trade squabbles. Both countries need to keep the big picture in mind—North Korea isn't going to wait for them to sort out e-commerce disputes.
