After a G7 meeting at which his behaviour was eccentric even by his own high standards, Donald Trump has added new and complex layers to the question of how on earth the other big trading powers should deal with him. This is one of the few areas in which experience does not necessarily bring wisdom. The US president’s actions are now so volatile that each extra piece of data, if anything, makes it harder rather than easier to discern his decision criteria and create a game plan accordingly.
在这次七国集团(G7)会议上,唐纳德•特朗普(Donald Trump)的行为即便以他自己的标准来衡量也可说非常怪异,让“其他贸易大国究竟应该如何与他打交道”这个问题变得更加复杂。这是为数不多的几个经验不一定带来智慧的领域之一。如今,特朗普的行为相当反复无常,以至于每一项额外数据(如果有的话)都让确定他的决定所依据的标准并制定相应计划变得更难、而不是更容易。
