求英语高手解释这句的语法

The European Union said it is willing to start formal financial-support talks with Hungary是句子的主干,The European Union是主语,said谓语,be willing to do固定搭配,表愿意做某事；之后 easing 动名词表伴随,解释主句中EU这样行动的目的,ease缓解什么呢,缓解的是standoff（僵局）,months-long修饰standoff,什么样的僵局呢,用over介词引导出an aid request ；that是request的宾语从句,这个从句很长,单拿出来是the request has become tangled.后面的 in a broader battle between Brussels and Budapest over democratic checks and balances其实都可以省去,对句子主要结构没有影响.
