The second argument made by the US Treasury and the Trade Representative is that no sufficiently precise currency rules can be negotiated. But there is nothing wrong with the IMF guidelines – both the 2007 and 2012 versions – negotiated by the Treasury itself.
美国财政部和贸易代表的第二个理由是可谈判的货币规则不够明确。但由美国财政部谈成的IMF的指引毫无问题——2007版和2012版均是如此。
