Asian Games organisers in Nagoya caused controversy by mistakenly playing which country's national anthem for South Korea?

Explanation: Asian Games organisers mistakenly played the North Korean anthem for South Korea, angering South Korean officials ahead of the opening ceremony. Protocol errors involving national anthems and flags are considered diplomatically sensitive at major multi-sport events, particularly given the tense and complex relationship between the two Koreas. The mishap added to a series of organisational difficulties reported ahead of the Games, including housing shortages linked to a record number of participants.
