The dynamics of diplomatic relations between the United States and China have been the focus of global attention for decades. These two countries, as the largest economic powers in the world, have complex and diverse interactions, including political, economic, military and cultural aspects. One of the key factors in this relationship is China’s rapid economic growth since the late 20s. China has succeeded in shifting the position of the United States as the leader of global trade. In this context, tariffs and trade policy become key issues, with both countries imposing duties on each other’s imports. These tensions peaked during the trade war under Donald Trump, who demanded China change trade practices it deemed unfair. Foreign policy also influences relations between the two countries. China has demonstrated its military escalation in the South China Sea, which has sparked concerns in the US and other Southeast Asian countries. The international community views China’s actions as an attempt to assert dominance in this strategic area. The United States, as part of its strategy to counter Chinese influence, is seeking to strengthen alliances with allied countries in the region, including Japan, South Korea and Australia. On the human rights side, relations between the two countries are also experiencing tension. The US often criticizes human rights violations that occur in China, especially regarding the treatment of Uyghurs and Hong Kong. China’s response to this criticism was to accuse the US of interfering in their internal affairs, sparking more diplomatic friction. Cultural aspects also play an important role in this relationship. Student exchange programs, cultural exports, and cooperation in the field of scientific research often act as bridges between the two countries. Even though diplomatic relations look bleak, interactions on the cultural front can help ease tensions. The climate issue is a common agenda that is starting to get attention. Both countries agree that climate change is a global challenge that requires collaboration. In this context, they are committed to reducing carbon emissions and increasing the use of renewable energy. Technological developments are also in the spotlight. The US is concerned about China’s dominance in advanced technologies, such as artificial intelligence and 5G. Policies to limit China’s access to sensitive technology are part of a strategy to maintain US technological superiority. Overall, the dynamics of diplomatic relations between the United States and China reflect a broader global power struggle. Tensions in various aspects are challenges that both countries must overcome to achieve stability and mutual prosperity on the international stage.
