Wales will play South Korea at home in a friendly in September.
This will be the first time the two countries have met at senior men’s level and will take place at Cardiff City Stadium on 7 September, four days before Wales’ Euro 2024 qualifier in Latvia.
South Korea, captained by Tottenham striker Son Heung-min, reached the round of 16 of the 2022 World Cup in Qatar.
Former Germany and USA national team coach Jurgen Klinsmann was named head coach of South Korea in February.
“Many teams in Europe are linked by qualifiers and it’s not always easy to get strong opposition on the rare occasions when we have the opportunity to play friendly matches,” said Noel Mooney, chief executive of the Football Association of Wales.
“So having players like Son Heung Min – Ben Davies’ teammate at Spurs – and many other high quality players coming to Cardiff is great for us.
“They had a really good World Cup playoffs and it’s important that we keep testing ourselves in different styles of football.
“South Korea is offering us a really interesting chance to do this and I’m sure we’ll have another great crowd supporting Cymru before Red Wall heads to Riga in a few days.”
Wales are planning to play an October friendly against Gibraltar at Wrexham Racecourse.
A friendly match against Trinidad and Tobago in March 2019 is the only time a senior Wales men’s team has played at the Hippodrome – the world’s oldest international football stadium still hosting matches – in the last 15 years.
Wales manager Rob Page announced his squad for next month’s Euro 2024 qualifiers against Armenia and Turkey on Tuesday, after picking up four points from their first two games in March.
