Joint bidding for FIFA World Cup

FIFA formally held joint bidding since 2002, which was approved for South Korea and Japan. Co-hosting did not happen again and it did not allow from 2004. FIFA allowed this again in 2018, these include only one organizing committee per joint bid, unlike Korea-Japan, which had two different organising committees.

FIFA did allow this in 2002, 2018, 2022, 2026, 2030 and 2034.
