Diplomatic relations between China and the United States (US) have experienced significant dynamics in recent years, reflecting changes in foreign policy, the economy and global challenges. In the current geopolitical context, both countries are trying to navigate tensions arising from various issues, including trade, technology and security. One of the main factors in the development of this relationship was the trade war that began in 2018. The tariff policy imposed by the US on Chinese goods caused a significant impact on the economies of both countries. Despite a temporary agreement in January 2020, tensions remain, especially in the technology sector, where the US has sought to limit the access of Chinese companies, such as Huawei, to global markets. Technology is the main arena of competition between China and the US. In the fields of 5G, artificial intelligence and semiconductor development, the two countries are competing to dominate innovation. The policies taken by the US to encourage domestic production of semiconductors and limit technology exports to China have exacerbated tensions. In this context, China responded by increasing investment in local technology research and development. The issue of climate change is also an area where the two countries have common interests. In several international meetings, both parties agreed on the importance of collaboration to overcome this global challenge. China is committed to reaching peak carbon emissions before 2030 and becoming carbon neutral by 2060, while the US seeks to lead global initiatives through environmentally friendly policies. Furthermore, human rights issues, especially regarding Xinjiang and Hong Kong, continue to be a stumbling block. The US frequently condemns China’s policies in both of these areas, creating tensions in diplomatic dialogue. Sanction measures by the US government against Chinese government officials made matters worse, while China denounced foreign interference in its domestic affairs. Military influence also reflects these twists in diplomatic relations. The increased naval presence in the South China Sea, and US military exercises with its allies, add a new layer to the competitive dynamic. China considers the US action a provocation, while the US argues that it is seeking to defend freedom of navigation. When looking ahead, summit meetings between the leaders of the two countries, such as the G20 meeting, will be important to ease tensions. Open discussions on various issues, including cybersecurity and post-pandemic economic recovery, can create space for more constructive diplomacy. To improve relations, both countries need to adjust expectations and listen to each other’s concerns. While China pursues a sustainable economic growth model, the US must consider the impact of its policies on global stability and bilateral relations. Overall, recent developments in China and US diplomatic relations are complex and require careful handling. Opportunities for collaboration exist, but the challenges that exist cannot be ignored. Public education on these issues is important, so that both the Chinese and US people understand the nuances in the relationship between these two global powers.
