Hi OptimusPrimea1, if you're referring to poets and quants, they've actually corrected their story.
Corrected version:
"The Financial Times also made a point in noting that Hong Kong’s University of Science and Technology Business School fell four places to tenth in the new ranking, and the newspaper said the decline is ”partly explained by a reclassification of students, faculty members and board members from China, previously counted as international by the FT for schools based in Hong Kong.” Those factors are among 20 different data points in the methodology used by the FT to rank MBA programs."
Old version:
“The Financial Times also conceded that an error in last year’s ranking allowed Hong Kong’s University of Science and Technology Business School to place sixth in 2011. The school fell four places to tenth in the new ranking and the newspaper said that the decline is ”partly explained by a reclassification of students, faculty members and board members from China, previously counted as international by the FT for schools based in Hong Kong.” Those factors are among 20 different data points in the methodology used by the FT to rank MBA programs.” (Wrong facts-See page 35 of the FT Business Education insert)
Basically, in all of its prior rankings, the FT considered China students in Hong Kong schools as international. However for the 2012 ranking, they made a change to the classification and no longer count China students as international for schools based in Hong Kong.
