Washington and Seoul discussing new deal on cost sharing for US troops in South Korea ahead of a potential Trump election victory

Washington and Seoul may strike a cost-sharing agreement for US forces based in South Korea before the end of the year — even though the current agreement does not expire until the end of 2025 — as both sides feel a sense of urgency to get a new deal solidified before the possibility of a second Trump administration, according to two US officials and two former US officials familiar with the discussions.

The negotiations over the Special Measures Agreement, known as the SMA, strained the US-South Korea alliance during the Trump administration. Former President Donald Trump demanded Seoul pay up to 400% more for the presence of the 28,500 US troops in the country during negotiations over the current agreement.
