Recent developments in diplomatic relations between the United States (US) and China show complex and varied dynamics. In recent years, the two countries have faced various challenges that have affected their interactions, both politically, economically and socially. In 2023, tensions in the Indo-Pacific region will increase, especially regarding the Taiwan issue and territorial claims in the South China Sea. The Pentagon has increased its military presence in the area, while China has responded by increasing military exercises. The two countries are also involved in challenging trade negotiations. The agreement signed in 2020 has not been fully implemented, and tariffs still apply to a number of goods. However, diplomatic efforts to improve relations have been made. In the meeting between the leaders of the US and China, the focus on the issue of climate change and global security was at the top of the agenda, considering the need for the two countries to collaborate in facing global challenges. Technology is also an important area of ​​contention between the US and China. The US decision to limit exports of chips and advanced technology to China has had a significant impact on China’s technology industry. On the other hand, China is trying to strengthen its domestic technology sector with massive investments in research and development, seeking to reduce dependence on foreign technology. Human rights issues in Xinjiang and the political situation in Hong Kong are also driving tensions in diplomatic relations. The US response to human rights abuses, including sanctions against Chinese officials, has further escalated the situation. China rejects these accusations and accuses the US of interfering in domestic affairs. In the context of international organizations, the US and China are trying to expand their influence through institutions such as the UN and G20. Both seek to promote their respective visions of global governance. China’s mission to spread Belt and Road Initiative projects in various countries is also a concern for the US, which sees it as an attempt to expand China’s political influence. High-level meetings between diplomats from the two countries, such as the US Secretary of State and the Chinese Foreign Minister, often take place with the aim of easing tensions. However, the results of these meetings often do not lead to significant change, and sharp rhetoric persists. Civil society in both countries is starting to play a role in shaping public opinion about this relationship. Social media and other online platforms allow individuals to voice their opinions on issues affecting US and China relations. The pro-democracy movement and human rights advocacy in Hong Kong are in the spotlight among US civil society, which is pushing their government to take a tough stance against China. On the other hand, anti-US sentiment in China is also increasing, especially among the younger generation, who often feel that their country is being treated unfairly. This creates additional challenges for the leaders of both countries in rebuilding lost trust. Despite the challenges faced, the potential for cooperation remains. Joint initiatives in the health sector, such as the response to the COVID-19 pandemic and vaccine research, show that when two countries come together, they can tackle pressing global issues.
