Oasis have expressed their disappointment at the move
Oasis' debut concerts in China have been cancelled after the authorities revoked the band's licences to play, deeming them "unsuitable".
Shows in Beijing and Shanghai due to take place next month have been pulled, and fans are to be reimbursed.
Concert promoters said the Chinese culture ministry recently found out that Noel Gallagher played at a Free Tibet benefit in the US in 1997.
The rest of the band's South-East Asian tour will go ahead as planned.
In a statement issued through their publicists, Oasis said they were "extremely disappointed" about the news, and hoped the Chinese authorities would "reconsider their decision".
Organisers said that the immigration and licensing processes for the concerts had been completed before tickets went on sale.
The band are currently touring the world to promote their current release Dig Out Your Soul.
Other acts have encountered difficulties in playing China, which is celebrating the 60th anniversary since the foundation of the People's Republic this year.
Rapper Jay-Z was denied permission to perform in 2006 due to his use of profane language.
And Britney Spears was permitted to play the country in 2004 on the understanding that her costumes were not too revealing.
Last year, Icelandic star Bjork shouted "Tibet! Tibet!" after a song about independence performed during a Shanghai concert.
Correction 4 March 2009: An earlier version of this story wrongly reported that Bjork had shouted "Free Tibet!" during a Shanghai concert in 2008, and that this had gone unreported by the state-controlled Chinese media.
