What Happened

• South Korea decided to expand the operational area of its anti-piracy unit already deployed in the Gulf of Aden to cover Hormuz Strait, without joining the U.S.-led International Maritime Security Construct (IMSC).
• The U.S. Government welcomed Seoul’s decision to expand operations to the Persian Gulf.
• Iran has expressed “concern” about the troop deployment, but also noted that it “understands South Korea’s decision.”
• There was some domestic push back; however, according to polls, 51.9 percent of South Korean support the troop deployment.

Implications: The South Korean government’s decision to dispatch troops to the Strait of Hormuz exemplifies South Korean idea of “balanced” diplomacy – accommodating different demands of surrounding powers while also avoiding any direct conflicts. South Korea partially conformed to the American request by expanding the Cheonghae Unit’s operational zone, but minimizing the risk of directly provoking Iran by not joining the IMSC.

The government also bypassed the difficulty of getting domestic approval for overseas troop deployment by framing it as an “extension” of the existing operation, rather than commencing a new mission. According to the law, the government needs parliamentary approval for overseas troop deployment. However, such consent is unnecessary for expanding the operation zone of a deployed unit.

Context: South Korea has managed to achieve a relatively successful balancing act between the demands of its most important ally and a potentially important future trade partner. South Korea was the 4th largest exporter to Iran in 2011. After the conclusion of the 2015 Iran nuclear deal, Korean exports to Iran grew from $6.1 billion to $12 billion in 2017. South Korea also imported approximately 230,000 barrels per day from Iran in 2011. The reimposition of U.S. sanctions on Iran in 2018 suspended this deep commercial relationship, but Seoul likely hopes for a speedy resolution of the tensions and the lifting of sanctions to reengage the growing consumer market in Iran.
