To do a book on the United States, China and International Economic Law is to consider an idea of overcoming. These countries have contributed much to the world and continue to do so. On this occasion, we go inside them, that is, how the United States and China function, as well as the proposals of International Economic Law. When we start an investigation we will not know what will come out of it, however, the novel results are very interesting and verifiable and by using only primary sources (not easy to obtain), anyone can go into them and learn more about these topics.
