Two weeks after U.S. President Donald Trump and South Korean President Lee Jae Myung announced a breakthrough on trade and security talks, no formal agreement has been released. The delay reportedly hinges on Seoul’s push to secure U.S. approval for building a nuclear-powered submarine.

Why It Matters:
The submarine issue exposes tensions over technology transfer and defense autonomy. Seoul says it has U.S. approval to use nuclear fuel, but Washington remains cautious about allowing sensitive submarine technology to be built in South Korea a move that could reshape regional power dynamics in East Asia.

South Korea: Seeking U.S. backing to build, not just fuel, a nuclear submarine domestically.

United States: Weighing strategic benefits against proliferation and security risks.

President Trump & President Lee: Keen to finalize a broader trade and security deal worth $350 billion in investments.

Regional Powers (China, Japan, North Korea): Watching closely for shifts in regional military balance.

What’s Next:
Officials say the draft on tariffs and trade is ready but awaits the final “factsheet” on security. The submarine wording remains under review by multiple U.S. departments. Both sides are expected to announce the full deal once the dispute is settled and a memorandum of understanding is signed.
