MBC's 'King of the Masked Singer' has yet to receive payment from Chinese broadcasters who bought the license rights to remake the show. The show is now proceeding to take the matter to court.
It was reported on September 18th that MBC has not received any payments after 4 seasons of China's version of the show have run. The contract for licensing was established in 2015 but the Chinese version's producers are saying that after season 1, the producers changed the name of the show and are now saying that they were the origin of the idea for the show.
It seems Chinese show's fate may be unclear as China does not have strict laws for royalties.
