Recent developments in diplomatic relations between the United States (US) and China show complex and varied dynamics. There are several key factors that influence interactions between the two countries, including trade issues, regional security, and diplomatic duties. In the trade sector, both countries still face major challenges. Despite efforts to negotiate a deal, tensions remain due to high tariffs imposed during the trade war. In 2023, the US set new restrictions on technology goods from China, aimed at protecting national security. This decision has the potential to trigger a response from China and cause further tension in bilateral relations. Security issues are a major concern. The increasing military presence in the South China Sea by China and the US reaction to it creates constant tension. Military exercises carried out by the two countries often result in tense communications. The US is also increasing diplomatic and military cooperation with its regional allies, such as Japan and Australia, demonstrating a commitment to confronting China’s growing influence. On the other hand, environmental aspects have also become a new focal point in diplomacy. Both the US and China, as the two largest emitting countries in the world, are experiencing global pressure to take real action on climate change. In recent months, there has been dialogue between the two countries regarding clean energy and sustainability initiatives, although debate over each party’s responsibilities and contributions remains an obstacle. Apart from that, human rights issues are also an inseparable component of diplomacy between the two countries. The US response to China’s treatment of the Uighur minority in Xinjiang and the political situation in Hong Kong are in the international spotlight. The US continues sanctions against Chinese officials deemed responsible for human rights abuses, causing further tensions. High-level meetings between the leaders of the two countries also took place, where dialogue on various issues took place. Although the two countries remain divided in their views, there is awareness of the need for better communication to avoid open conflict. It is hoped that this meeting will improve communication channels and allow both parties to find common ground on sensitive issues. Finally, the existence of multilateral platforms, such as the G20 and COP26, helps bring the US and China together in a broader context. Both must be cooperative in dealing with global issues, such as post-pandemic economic recovery and the climate crisis. This dialogue provides an opportunity to forge a more constructive relationship, even though challenges still dominate the bilateral agenda. Overall, recent developments in diplomatic relations between the US and China are filled with challenges but also opportunities. In facing this complex reality, it is important to observe how the two countries manage their differences and find ways to work together for global stability.
