这就是所谓的互惠原则。

This is called The Law of Reciprocity.

但随着国际间交往的发展，越来越多的国家开始放弃互惠原则，或者对互惠原则进行软化处理。

However, with the development of international transactions, more and more countries begin to abandon or weaken this principle.

这正是互惠原则的最好体现。 其实在我们的业务中有很多这样子的例子，我们的同事每天也在不断贯彻五大原则，并利用它来做各种决定。

This is the only one example of many examples in our businesses, where Everyday our associate exercises the five principles in the way we take decision and the way we behave.
