As mr lipmann points out , this is not the first time that policymakers worrying about metal supplies have fumbled their response .

李普曼指出，政策制定者以前就曾因担忧金属供应问题而胡乱出招。

" China does not want to supply rare earth to build a prius or volt car battery : it wants to build and market the vehicle , " says anthony lipmann of lipmann walton , a uk-based trader .

“中国想要的不是向别人供应稀土元素，让他们去制造普锐斯或volt汽车的电池，而是自己制造和销售汽车，”英国李普曼沃尔顿（lipmannwalton）贸易公司的安东尼李普曼（anthonylipmann）表示。
