Global South solidarity? China, regional organisations and intervention in the Libyan and Syrian civil wars

Why was China responsive to regional organisations' call for intervention in the case of the Libya crisis, where it supported sanctions and an International Criminal Court referral, and acquiesced to a no-fly zone, but unresponsive to pressure from regional organisations for intervention in the Syria crisis, issuing repeated vetoes instead? Using interviews and other primary data, this article explains the variation by highlighting that China is most responsive to regional organisations when these groups remain cohesive, congregate around the same policy position and when they publicly criticise or isolate China.
