Academic freedom is best understood not as an abstract universal principle or an ideal state of being but as concrete university practices nested in specific relational environments. As such, practices of academic freedom vary across the world, according to variations in political cultures, educational cultures and state-university relations. The article discusses these variations with particular reference to differences between universities associated with the limited liberal states of the English-speaking world, and those associated with comprehensive East Asian states in the Sinic tradition, including China. Given the different traditions there is no point in imposing judgments on one system in terms of the norms of another, but worth exploring the potential for common ground. Any world-wide approach to academic freedom would need to combine a universal element with space for context-specific elements.
