South Korea toward Iran

-20

South Korea froze Iranian funds in compliance with sanctions, disrupting bilateral financial ties. Its government also pursued arrangements to use or transfer Iranian funds for humanitarian purposes, including a 2023 transfer arrangement, reflecting diplomatic engagement alongside sanctions compliance.

Overall relationship

-20

The relationship has been shaped by sanctions-constrained economic ties, particularly the interruption of Iranian oil imports and the freezing of Iranian funds in South Korea. Diplomatic efforts to address those funds have coexisted with serious friction, including Iran's seizure of a South Korean-flagged tanker. These durable constraints and disputes outweigh the limited evidence of practical cooperation.
