The World Baseball Softball Confederation (WBSC) has unveiled the draw for this year's Under-18 Baseball World Cup.
Hosts and 2017 runners-up South Korea headline Group A and are placed with two other teams in the world's top 10, Australia and the Netherlands, as well as Canada, Nicaragua and China.
Group B features the world's number one side, Japan, four-time defending champions United States and a strong Chinese Taipei team, alongside Panama, South Africa and Spain.
"Both groups feature the best youth teams in the world and this will create a very intense opening round," said WBSC President Riccardo Fraccari.
"The Under-18 Baseball World Cup is one of the most prestigious international events in the youth sports space, with players who have done well here going on to stardom and securing some of the most lucrative contracts in sports."
The tournament is due to be staged from August 30 to September 8 at Gijang-Hyundai Dream Ballpark in Gijang, Republic.
The top three teams from Group A will play the top three from Group B in the super round from September 5 to 7, with the top two teams meeting in the final on Sunday, 8 September.
