SEOUL, April 16 (AJP) - South Korea is reviewing participation in an international effort to secure the Strait of Hormuz, with the presidential office and defense ministry weighing roles in a postwar multinational force.

The presidential office said on Thursday that President Lee Jae Myung is reviewing participation in an international virtual meeting on the Strait of Hormuz scheduled for Friday, to be led by the United Kingdom and France, according to officials. 

The official said around 70 to 80 participants, including international organizations, have been invited.

Defense Minister Ahn Gyu-back told a parliamentary hearing on Tuesday that the United Kingdom and France are leading discussions on forming a postwar maritime force, and that Seoul has already signaled its willingness to participate.

“As a responsible member of the international community, we are preparing step-by-step plans,” Ahn said, noting that the military has outlined a four-phase strategy in coordination with the Joint Chiefs of Staff and the Defense Ministry.

A military source said options under review range from dispatching personnel to a multinational command structure to providing remote support without a direct deployment to the strait.

French President Emmanuel Macron said Tuesday the initiative would take the form of an international security mission excluding parties directly involved in the conflict — namely the United States, Israel and Iran. The European-led framework aims to ensure safe navigation through the strait even after active fighting subsides, though officials cautioned that restoring full maritime operations could take time.

Germany, historically cautious about overseas deployments, is also likely to participate, according to a senior official. Its involvement would broaden the scope of the mission, given Berlin’s financial resources and key military capabilities.

Seoul has already taken part in online consultations led by the UK and France. Joint Chiefs of Staff Chair Jin Young-seung joined videoconference discussions on March 26 and again on Wednesday, alongside parallel vice foreign minister-level talks.

With limited allied support to reopen the chokepoint — where traffic has dwindled under tight Iranian control — Washington has moved unilaterally. U.S. forces began a “reverse blockade” on Iranian activities over the water corridor since earlier this week.

President Donald Trump said on Truth Social that the United States had begun “clearing out” the strait “as a favor” to countries including China, Japan, South Korea, France and Germany, while criticizing them for failing to act.

Despite a ceasefire, uncertainty persists over when the strait can fully reopen. A report by The New York Times said Iran has been unable to locate or remove naval mines it previously deployed, complicating efforts to resume maritime traffic.

Citing U.S. officials, the report added that Tehran may not have recorded the precise locations of all the mines, some of which were designed to drift with ocean currents. While Iran has released maps indicating safe routes, those corridors are considered limited.

Analysts say South Korea could be assigned mine-clearing duties if it joins the mission.
“Possible roles would likely include mine removal, securing the strait and escorting oil tankers,” said Jeong Kyung-woon, a researcher at the Korea Association of Military Studies. He added that even the formation of a multinational naval force could itself serve as pressure on Iran by narrowing its strategic options.

Ahn emphasized that any deployment would only take place after the war ends.
Experts urged caution.

“While South Korea is allied with the United States, it is important to avoid being drawn into a conflict that is not directly our own,” said Choi Gi-il, a professor of military studies at Sangji University.

Separately, top naval commanders from South Korea, the United States and Japan held talks in Seoul on Wednesday — the first such trilateral meeting since 2022 — fueling speculation that Washington may seek broader allied support for Hormuz-related operations.
