United Asian Debating Championship (UADC) is an annual debating tournament for teams from universities in Asia. It is the largest inter-varsity Parliamentary Debate tournament in Asia, with over 600 participants. The UADC holds debates in the Asian 3-on-3 format Parliamentary Debating. The UADC was created after a decision to merge the two separate championships that were held after the Asian Debating community split in 2005 – the Asian Universities Debating Championship (AUDC) and the All-Asian Intervarsity Debating Championship(AIDC or “All-Asians”). The decision to unite the two competing tournaments, and thus, create a single debate championship for Asia was taken at the last Asian Universities Debating Championships in 2009.
