The hosts are hoping to bounce back from consecutive defeats, while South Korea are still searching for the first victory of Jurgen Klinsmann's tenure.
Match preview
Thursday's fixture may only be a friendly encounter, but Wales boss Rob Page will be eager to pick up a victory after seeing his position called into question following a poor start to their Euro 2024 qualifying campaign.
The early signs were actually positive after Wales scored a late equaliser to take a point off Croatia before they claimed a narrow 1-0 victory over Latvia.
However, a surprise 4-2 home defeat to Armenia and a 2-0 loss away to Turkey have left Wales in fourth position in Group D and pile the pressure on Page.
Having won just two of their last 15 internationals (D4, L9), Wales will be keen to restore an element of belief before they travel to Latvia for Monday's Euro 2024 qualifier.
However, the Dragons will be discouraged by the fact they are winless in four friendly matches (D3, L1) since beating Mexico 1-0 in March 2021.
South Korea will be targeting their first win since edging out Portugal in the 2022 World Cup group stage when they travel to Cardiff this week.
Since being eliminated by Brazil at the last-16 stage, South Korea have experienced a change in manager after Klinsmann was named as Paulo Bento's successor.
The former USA boss has experienced a rocky start to his tenure, which began with a 2-2 draw against Colombia, before South Korea were beaten by Uruguay and Peru.
The 59-year-old looked set to finally claim his first victory as South Korea manager when Hwang Ui-jo opened the scoring in June's friendly with El Salvador, but Alex Roldan levelled the scoreline in the 87th minute to leave Klinsmann waiting for his maiden win.
Having conceded in each of their last eight internationals, the Taegeuk Warriors need to shore up defensively if they are to return to winning ways in their next two friendlies against Wales and Saudi Arabia.
