The dynamics of diplomatic relations between the United States (US) and China have become an important topic in the global arena in recent decades. Since the end of the Cold War, these two countries have experienced fluctuations in their relations, which can be seen through political, economic, and military approaches. These diverse relationships are often influenced by issues such as trade, human rights and regional security. In terms of trade, the tariff conflict that started in 2018 is a major highlight. The Trump administration imposed high tariffs on Chinese goods, claiming this was to protect domestic industry. These actions created tensions that resulted in retaliation from China in the form of tariffs on US products. Since then, despite efforts to negotiate, trade tensions have remained, creating far-reaching global impacts. The issue of human rights is also a sensitive point. The US frequently criticizes China’s policies in Xinjiang and Hong Kong, accusing Beijing of human rights abuses. China’s response was to view the criticism as interference in its internal affairs. When the US imposes sanctions on Chinese individuals and entities, Beijing responds with counter-sanctions. In the military field, China’s closeness to Russia and its increasing military strength in the South China Sea are of concern to the US. China claims most of the South China Sea, which is also claimed by several ASEAN countries. The US, which has geographic and strategic interests in the region, frequently carries out freedom of navigation operations, which Beijing often views as provocative. In the context of multi-lateral diplomacy, these two countries are involved in various international organizations such as the UN, where they seek to influence policies globally. The US is trying to build alliances with allied countries such as Japan, Australia and India to balance China’s influence in the Indo-Pacific region. Meanwhile, China is strengthening relations with developing countries through the Belt and Road initiative. The economic interdependence between the two countries is also worth noting. The US is a major market for Chinese goods, while China is one of the two largest creditors of the US national debt. This dependency creates a delicate network that requires both to maintain some form of cooperation despite existing tensions. The dynamics of relations between the US and China are very complex and continue to evolve. There is always a chance for this relationship to improve, especially on global issues such as climate change and public health. Open dialogue and multilateral diplomacy are the keys to resolving existing conflicts and ensuring regional and global stability for future generations. Looking ahead, many factors will influence the direction of this relationship, including changes in political leadership and global economic dynamics. Over time, a deeper understanding of these complexities will be critical to maintaining peace and cooperation on the international stage.
