The essential idea is quite simple: in the long run, an international monetary system cannot be built on a national currency – a point made a half-century ago by the Belgian-American economist Robert Triffin. Recognition of this fundamental problem was the reason why the IMF’s Special Drawing Rights (SDRs) were created in the 1960’s.
要求建立新的全球储备体系所基于的核心观点相当简单：长期来看，国际货币体系不可能建立在一个主权国家的货币之上——比利时裔美国人罗伯特·特里芬早在半个世纪之前就表达了这样的观点。国际货币基金组织于20世纪60年代创立特别提款权(SDRs)，就是因为世界各国认识到了这一根本问题。
