The competition brings together England, Scotland and Wales to play across three days of basketball action.
Sterling Muschett will lead the U14 Boys team, with Steven Lindsey set to oversee the U14 Girls programme.
The event will serve as an excellent opportunity for players to continue their development at the international level, with a view to progressing along the England Talent Pathway (ETP) and towards a potential GB spot for future FIBA European Championships.
All three countries have entered two teams into each competition, with the only exception being Wales putting just one girls' team forward.
Friday evening saw an opening ceremony followed by 3x3 activity. The Tri-Nations tournament takes place over the weekend, with both girls and boys playing throughout both days.
The Dundee showdown follows the U18s event in Cardiff last month, when England’s men and women had a clean sweep of wins, as well as the U16s Four Nations last weekend that also included a number of victories.

"After excellent tournaments for the U18s and U16s in recent weeks, it will be great to get the U14s on court against some of the best players from Scotland and Wales.
“We place a premium on making sure our young players gain the experience and opportunities needed for their development and playing competitive games in this kind of environment is certainly a part of that.
“We want to see players this weekend building on what they have learned so far and putting the pieces in place to continue their journey.”
