While not necessarily intended to be a rival tournament, the last three AUDCs coincided with the schedule of the All-Asian Championship, which made it impracticable for teams to attend both tournaments.
Universiti Kebangsaan Malaysia, which was one of the founding institutions of AUDC and entered teams in the AUDC in 2005 and 2006, chose to attend the All-Asians Championship in 2007. Among the universities that won the All-Asians prior to the split, they are the only institution to have participated in the All-Asians since the inception of the AUDC. They attended AUDC again in 2008.
