Recent developments in diplomatic relations between China and the United States demonstrate complex and often contradictory dynamics. Relations between these two countries are not only influenced by economic interests, but also by political, security and human rights issues. One significant development is increased dialogue between the leaders of the two countries. The meeting between US President Joe Biden and Chinese President Xi Jinping showed a desire to reduce tensions and establish communication channels. Both countries agreed on the need to maintain regional stability and avoid unnecessary conflict. This dialogue also covered climate issues, where the two countries agreed to increase cooperation in efforts to deal with global climate change. In the economic field, trade remains a central issue. Despite efforts to repair trade relations damaged by tariffs and protectionist policies, tensions may re-emerge due to technological competition. Initiatives such as “Made in China 2025” and the US focus on national security in terms of technology are points of contention. Policies such as export restrictions on Chinese technology companies by the US show concerns about technological dominance. Human rights issues also continue to be a stumbling block. China’s actions in Xinjiang and Tibet and its handling of demonstrations in Hong Kong sparked sharp criticism from the US. Sanctions imposed by the US on Chinese officials in response to human rights abuses have exacerbated tensions. This was accompanied by calls from some members of the US Congress to adopt a tougher policy towards China. In the military field, China’s military activities in the South China Sea and Taiwan are a source of tension. The US is increasing military support for Taiwan and conducting joint military exercises with allied countries in the region, which China considers a provocation. Increasing maritime surveillance and arms supplies to Taiwan are important steps for the US in demonstrating its commitment to East Asian security. Both countries are also involved in competition in the global arena, including in international organizations. China seeks to strengthen its influence through the Belt and Road initiative, while the US seeks to build alliances to respond to challenges arising from Chinese influence. Cooperation on global health issues, although limited, also shows potential for future collaboration. COVID-19 is a reminder of the importance of international cooperation in facing global problems, but the rise of nationalism often hinders progress. Social media and information have also become a new battle arena. Disinformation and propaganda from both sides has the potential to influence public opinion and create further tensions. China uses state communications tools to reinforce positive narratives about its policies, while the US seeks to promote democracy and freedom. The energy crisis and climate change, which are also global issues, provide opportunities for further dialogue. Each country has a responsibility to reduce greenhouse gas emissions and invest in renewable energy. Collaboration in research and green technology could be a starting point for repairing already strained relations. In terms of technological developments, competition in the fields of AI and 5G is in the spotlight. The US is executing policies to limit Chinese companies’ access to high technology, which could lead to a new technological arms race. In contrast, China continues to invest in developing its own technology to reduce dependence on foreign products. Recent developments in diplomatic relations between China and the United States reflect the complexity of various interrelated issues and require strategic policies to bridge differences. The balance between competition and collaboration will be a key challenge as both countries consider their roles on the global stage.
