I have just read the cricinfo article, which you mentioned. The exact words used are "The ban is because of pressure from Australia and England. There is no problem in Asia" . He has not said "White countries are trying to hold back cricketers from the subcontinent".
He is right about the pressure being from Australia (umpires calling hm for throwing) and England (Chris Broad).
Just seen another article on Bloomberg which confirms the words he used.(as above) (The article is titled: Murali,Cricket's Leading Bowler, Divides Players, Lawmakers.

I have also read in 'the Age' an interview by Shane Warne, where he suggests Murali should develop a thick skin regarding the criticism. The title of this article is 'Murali :over-sensitive to criticism : Warne' by Chloe Saltau, Harare. (

I think Warne does have a valid point.
