by的用法

To those who see the negotiations as the best opportunity to rebalance the trade relationship between Washington and Beijing, the prospect of rolling back tariffs without sweeping concessions by China would fail to achieve Mr. Trump’s goal of ending what he has deemed its unfair trade practices. 


请问,此句中by作什么词,by China在句中作什么成分?

sweeping concessions by China: 

by China 作定语,修饰sweeping concessions ,意为“中国所作的全面让步”。

by 引出“动作施事者”,可以认为动作made 被省略。相当于sweeping concessions made by China。又如:

a book (written)by Lu Xun  一本鲁迅写的书


网友看下面几个表达,仔细体会不同的介词表达什么意思:

a letter by Tom

a letter from Tom

a letter to Tom

a letter for Tom

a letter about Tom
