A now annual event on the Pacific rim and Asia with equaly sometimes bizaar clothes usualy with some heritage to the host nation being worn by the leaders in attendance notably from Australia, Indonesia, Russia, China, Chile, USA, Japan, Malaysia, Korea, Mexico, Canada, Phillipines, Peru, Vietnam, etc
Previous notable attire has been Red & Blue costumes from China and Ponchos from Mexico. In the tradition I am tipping this week in Sydney we will see these leaders in Drizabone coats, RM Williams boots and Akubra hats. And maybe depending on the mood of the conference a stockwhip as well.
EEC and EU eat your hearts out.
