International institutions work hard to achieve Sustainable Development Goals (SDGs) by implementing multilateral cooperating systems. Over the past decade of Chinese and United States leadership, however, organizations like UNSC, UNHRC and the WTO faced many challenges. This paper will analyse the structures of these organizations and present solutions to the problem that plagued them. The possible reforms for these three institutions, respectively, are to repair the relationship between states through future collaboration, equalize the representation power of each state by making the operation transparent, and protect the common principality with an independent enforcement body. In conclusion, we should reform these institutions as well as protect them from selfish exploitation from nations.
