Renberg's first international experience came at the European Junior Championship, in which he helped Sweden secure a gold medal by scoring 7 goals in 6 game against Europe's top competition. Renberg next wore the three crowns in the 1992 World Juniors and scored six goals and four assists, playing with future NHL stars Peter Forsberg, Michael Nylander, and Markus Näslund. Renberg finished fourth in the scoring behind his three aforementioned countrymen. Despite the high offensive output of the Swedes, they only returned home with a silver medal.
