GUANGZHOU, China - Cosplay and merchandise sales of popular Japanese anime series "Detective Conan" have been banned at some events in China since it drew backlash over recent collaboration with the manga series "My Hero Academia" that had previously been criticized for evoking Japan's wartime atrocities.

Such bans were introduced for recent events in Beijing, Chongqing and Lanzhou after many criticized the collaboration campaign between the two Japanese works as "insulting to Chinese people."
