A Thai female student was among those killed in a Halloween crush in Seoul on Saturday night, the Foreign Ministry said on Sunday evening.
The student was on a language course in South Korea, a Thai Foreign Ministry spokesman said later on Sunday.
He said said the victim was 27 and had studied the Korean language for two months. The embassy had informed her family and offered to help arrange for the body to be flown home.
All Thais were strongly advised by the embassy to avoid events throughout the country, it said.
South Korea has been one of the most popular destinations for Thai tourists since it lifted Covid-19 restrictions.
More than 150 people were killed in the crush as an estimated 100,000 people packed alleys and steep roads in the South Korean capital's Itaewon district. The crush took place at 10pm (8pm Thailand time) on Saturday.
South Korea has cancelled several events in the wake of the tragedy. Prime Minister Prayut Chan-o-cha joined other international leaders in offering condolences.
Meanwhile, Khao San Road is planning a Halloween party on Monday.
The Khao San Road Business Association will hold talks with Phra Nakhon district officials on safety measures and a plan to limit the number of people who can enter the area.
