The competition was won by Romania. Original plans called for them to receive an automatic berth into the following year's edition of the IRB Junior World Championship, the top tier of the IRB under-20 championship; however, Romania ultimately did not receive that berth after the Junior World Championship was reduced from 16 teams to 12.
