The Armenian National Teams come from the Eurasian country of Armenia.
Armenia is located in Western Asia. Although they have a Junior Quidditch programme, there are no wizarding sports listed on Armenia's Wikipedia page (Wikipedia). However, it was an Armenian warlock who saved a village from werewolf attacks (which Gilderoy Lockhart took credit for) - and, where there are wizards, there are wizard sports (CS16).

Although the date printed on the third Daily Prophet Newsletter (DP3) is 1 June 1999, the timeframe for the Quidditch event is 1992-1993.
