A ban must be formally announced by the official governing body or organizer of the event. This includes formal prohibitions, sanctions, suspensions, or exclusions that explicitly prohibit participation. Voluntary withdrawals, boycotts, or non-qualification due to poor performance do not count. Speculation or threats without official enforcement do not qualify. Individual bans may not constitute a country ban unless the individual is the sole representative. The ban only needs to be announced (not enforced) before the deadline to trigger resolution.
