The Chinese National Teams are from the Far Eastern country of China.
They lost the final of the 2010 Quidditch World Cup in an exciting and hard-fought 3-day match against Moldova (Pm).
During the qualifying rounds in the run-up to the Quidditch World Cup tournament in 2014, China lost their match against Liechtenstein – an unexpected upset result (Pm).
Although China was a participant in the 2010 and 2014 Quidditch World Cup tournaments, no Quidditch or other wizard sports teams are listed in its Wikipedia entry (Wikipedia).
