The dynamics of relations between the United States (US) and China on the global stage are increasingly complex, covering various political, economic and military aspects. In recent years, these two countries have been involved in intense competition that has not only affected the lives of people on both sides, but also had an impact on the international order. One of the main factors in this relationship is trade dissatisfaction. The US accuses China of implementing unfair trade practices, such as intellectual property theft and subsidies for state companies. In response, the US imposed high tariffs on Chinese goods, creating inevitable tensions. This trade war caused a significant impact on global markets and supply chains, affecting the economies of various countries. On the technology front, competition between the US and China is intensifying with increasing attention to artificial intelligence and 5G. China, through initiatives such as “Made in China 2025,” aims to become a global leader in high technology. The US responded by issuing bans on Chinese companies, such as Huawei, that it deemed a threat to national security. The decision creates uncertainty for investors and companies around the world. In terms of global politics, US-China relations also influence issues such as climate change, global security and human rights. At the Climate Change Conference, the US and China are often key to reaching global agreements. However, differing views on carbon emissions and developing country responsibilities often make collaboration difficult. The militarization of the South China Sea has become a major point of tension. China continues to expand its presence in the region, which is rich in natural resources. The US, committed to maintaining freedom of navigation, sent warships in protest against China’s territorial claims. This tension leads to the risk of greater confrontation in the future. Diplomacy is also an important tool in US-China relations. Under the leadership of President Joe Biden, the US is prioritizing a diplomatic approach, although at the same time remaining firm towards China’s policies. Through summits and dialogue, both countries have attempted to reduce tensions, although the results often do not reflect expectations. The scope of this diplomacy does not only involve the two countries directly, but also involves their allies. The US is trying to strengthen alliances with Southeast Asian and European countries to balance China’s power. Meanwhile, China is also building strategic partnerships with countries in Asia and Africa, amplifying its influence globally. One of the most interesting aspects of this dynamic is the impact on civil society. Social media campaigns, both in the US and China, create different narratives about each other, influencing public views. Propaganda and disinformation are often used to build a negative image that can influence government policy. In the long term, the influence of the US and China in the global order will continue to change. While the two compete for dominance in various fields, it is important to note that collaboration on global issues such as health, security, and the environment remains an integral part of their relationship. This balance between competition and cooperation will determine the future direction of international relations.
