The warship operated by the anti-piracy Cheonghae Unit sailed just one day after the MT Hankuk Chemi, a South Korean-flagged oil tanker, was stormed by armed Iranian Revolutionary Guard troops who forced the vessel’s crew to change course towards Iran over an unspecified investigation, according to the vessel’s owner.
“The Cheonghae Unit arrived in waters near the Hormuz Strait earlier in the day,” the military spokesperson said at the briefing. “It is carrying out missions to ensure the safety of our nationals.”
“The issue should be resolved through diplomacy,” the official said. “The unit is focused on the safety of our people who use the waterway after the seizure incident.”
Seoul’s foreign ministry called the Iranian ambassador on Tuesday for the early release of the oil tankers’ 20-member crew. However, Iran responded that the vessel is being held for “environmental and chemical pollution concerns” in the waters of the Persian Gulf and the Strait of Hormuz.
The seizure came as South Korea, in accordance with sanctions reimposed by the United States in 2018 after withdrawing from the Obama-era nuclear agreement, continues a freeze on $7 billion from Iran’s oil exports in two Korean banks. Tehran has been calling on Seoul since July 2020 to release the money.
The Islamic regime on Tuesday denied speculation that it is planning to exchange the captured ship for its $7 billion funds, offering its bluntest acknowledgment yet of a link with the frozen assets.
The 20 crew members on board the South Korean-flagged vessel include five South Koreans, 11 Myanmarese, two Indonesians, and two Vietnamese.
South Korea’s Vice Foreign Minister Choi Jong-kun is scheduled to visit Tehran on Sunday, a visit that was previously scheduled and during which a range of bilateral issues will be discussed, the ministry said on Tuesday.
Iran has a record of seizing foreign ships traveling near the strategic Strait of Hormuz as a method of gaining advantage in sanctions talks.
In 2019, Iran held a British tanker for two months after the United Kingdom seized an Iranian tanker that was suspected of carrying oil to Syria in violation of European Union sanctions.
