The main aim or my Thesis is to examine the relationship between the United States and China. As a first step, a historical insight of the U.S-Chinese relations after World War II will take place. Furthermore, the major focus will be on traded goods between the two countries, specifically, the case of Soybeans and steel, after and before the trade war. Finally, a possible weapon that China could abuse against the US, the case of rare earth elements RREs.
