SEOUL — South Korean authorities have faced a difficult legal barrier after government data revealed that 49 foreign diplomats were linked to criminal or other incidents in the country from 2022 through July 2026, with diplomatic immunity preventing South Korean authorities from pursuing ordinary criminal prosecution in cases where immunity was not waived.
The figures, submitted by the Ministry of Foreign Affairs to the National Assembly’s Foreign Affairs and Unification Committee, cover incidents ranging from traffic violations and theft to assault and alleged sexual violence, according to The Korea Herald.
The number has fluctuated in recent years:
- 2022: 10 cases
- 2023: 13 cases
- 2024: 10 cases
- 2025: 13 cases
- January–July 2026: 3 cases
That brings the reported total to 49 diplomats over the period.
The number may not tell the whole story
The data comes with an important limitation.
The Foreign Ministry figures cover cases reported to investigative authorities and subsequently notified to the ministry. That means the actual number of incidents involving foreign diplomats could be higher.
The cases also involved diplomats’ accompanying family members.
According to the government data, 12 incidents involved family members of foreign diplomats during the same period:
- 5 in 2022
- 2 in 2023
- 3 in 2024
- 1 in 2025
- 1 from January through July 2026.
Why can’t South Korea simply prosecute them?
The issue centers on diplomatic immunity, a protection recognized under the 1961 Vienna Convention on Diplomatic Relations.
Diplomatic agents generally enjoy immunity from the criminal jurisdiction of the country where they are stationed. Under the convention, the receiving country normally cannot prosecute an accredited diplomatic agent in its own courts unless the diplomat’s sending state expressly waives the immunity.
That does not mean diplomats are legally permitted to commit crimes.
In fact, the Vienna Convention specifically says diplomats have a duty to respect the laws and regulations of the receiving country.
The protection is therefore better understood as a restriction on the host country’s jurisdiction, rather than a declaration that the conduct itself is lawful.
South Korean police can still investigate
Diplomatic immunity does not necessarily mean that authorities simply ignore an allegation.
According to the reports, South Korean police can conduct a voluntary investigation with the diplomat’s consent.
However, if the sending country does not waive immunity, South Korean authorities cannot proceed with criminal prosecution in their courts even if investigators establish facts surrounding an alleged offense.
The sending state can also expressly waive the diplomat’s immunity, which would open the door to criminal proceedings in South Korea.
What if a person doesn’t identify themselves as a diplomat?
There is another important wrinkle.
If someone involved in an incident refuses to identify themselves as a diplomat, South Korean authorities may initially handle the matter under procedures applicable to other foreign nationals.
The diplomatic status can then affect how the case proceeds once that status is confirmed.
The figures are being reported across Korean media
The Korea Herald’s report was published on Sept. 10, 2026, based on Foreign Ministry data submitted to lawmakers.
Yonhap News Agency independently reported the same figure of 49 foreign diplomats, with the annual breakdown matching the Korea Herald’s report. Yonhap likewise said the incidents ranged from traffic violations and theft to assault and sexual violence.
The Korea Times also reported that 49 diplomats were involved in criminal or other incidents during the period, citing the same Foreign Ministry data.
Meanwhile, Korea JoongAng Daily reported that the 49 cases involved allegations including theft, assault and sexual violence and emphasized that the figures may not represent every incident because they only include cases reported to investigative authorities and later communicated to the Foreign Ministry.
That cross-check strengthens the central figure while also highlighting the need to avoid overstating what the data proves.
A wider diplomatic problem: traffic violations
The issue is not limited to criminal allegations.
Separate reporting this week found that vehicles belonging to foreign diplomatic missions in South Korea committed 4,117 traffic-law violations over roughly four and a half years, with speeding accounting for more than half of the violations.
U.S. diplomatic vehicles recorded the highest number in that separate dataset, followed by Russian diplomatic vehicles.
The two datasets should not be confused: the 49 figure concerns diplomats involved in reported incidents, while the 4,117 figure concerns traffic-law violations by vehicles of diplomatic missions.
What happens when immunity prevents prosecution?
When diplomatic immunity applies, South Korean authorities can document the circumstances but may have to close the case without prosecution in Korea.
The diplomat’s sending country retains jurisdiction, meaning immunity from South Korean courts does not necessarily mean immunity from consequences in the diplomat’s home country.
Diplomats can also face diplomatic consequences.
Under the Vienna Convention, a receiving state can declare a diplomatic agent persona non grata, effectively requiring the sending state to recall the diplomat or terminate their diplomatic functions.
The bigger question for South Korea
The disclosure of the 49 cases has reignited an old but difficult question in international diplomacy:
How should a country balance diplomatic privileges with accountability when allegations of serious wrongdoing arise on its territory?
Diplomatic immunity exists to protect diplomatic functions and prevent host governments from using criminal proceedings to interfere with foreign missions. But the same protection can create frustration when victims or the public expect alleged offenses to be handled through the country’s ordinary justice system.
The latest figures do not establish that all 49 diplomats committed crimes, nor do they mean that all 49 cases involved conduct that would have resulted in criminal convictions. The government data describes people who were reported as being involved in criminal or other incidents.
What the figures do show is a recurring jurisdictional challenge: when diplomatic immunity applies and is not waived, South Korea’s ability to prosecute an accredited foreign diplomat is sharply limited.
And with 49 reported cases since 2022 — plus 12 involving accompanying family members — the issue is unlikely to disappear from South Korea’s diplomatic and legal debate anytime soon.
