CURRENCY has proved to be one of the decisive weapons in the present war between Japan and China. Much though its importance is underrated by many close observers of the great conflict, the two participants have long been well aware of this fact. More than two years before military hostilities actually started, the SinoJapanese currency war was already in full swing.
