Recent developments in diplomatic relations between the United States (US) and China reflect the complex dynamics influencing global politics. In recent months, the two countries have experienced fluctuations in relations covering trade, security and technology issues. One significant step was a diplomatic meeting between the leaders of the two countries aimed at improving communication and reducing tensions. One of the main focuses in this relationship is trade competition. The US and China are engaged in negotiations to overcome tariffs imposed on both countries’ products. China demonstrated its commitment to increasing purchases of US agricultural products and expanding market access for US companies. This response, despite the existing challenges, is expected to stimulate better economic relations again. Technology issues are also an important pillar in diplomatic discussions. With the rise of AI and 5G technology, both countries are competing to become global leaders. The US is increasingly wary of Chinese investments in the technology sector, especially those related to national security. Restrictions on Chinese companies such as Huawei reflect the US’s defensive stance against technological developments it deems threatening. Apart from that, the situation in the South China Sea has exacerbated tensions. The US continues to express its support for allies in the region, while China strengthens its military presence. Joint military exercises between the US and Southeast Asian countries, such as the Philippines and Japan, demonstrate the US’ commitment to maintaining regional stability. China, on the other hand, responded by claiming rights to the disputed territory, underscoring the importance of the issue in diplomacy. In terms of climate change, US and China collaboration was seen through joint statements to increase global efforts to address environmental challenges. The COP26 meeting was held with the hope that the two countries could collaborate in developing green technology, even though there were gaps in their respective commitments. Facing these challenges, cultural diplomacy is also an important part. Student exchange programs and academic collaboration aim to increase intercultural understanding. This initiative, despite facing obstacles, played a significant role in creating more solid relations between the young generations of the two countries. The two countries also seek to balance dialogue on human rights issues. China has faced international criticism over its treatment of minorities, especially in Xinjiang. The US, in this context, insists that dialogue should cover these issues, even though China rejects foreign interference in its internal affairs. In the face of all these challenges, it is important for the US and China to establish effective communication channels. Back-channel diplomacy is an important instrument for resolving deep-seated disputes and ensuring relations remain constructive. Moreover, the ever-changing global situation encourages both countries to find common ground for mutual interests. All these aspects show that although US and China relations are full of challenges, efforts to manage differences and increase cooperation remain the main focus in the two countries’ diplomacy. A planned approach and open dialogue are the keys to maintaining stability and encouraging the continuation of mutually beneficial relationships.
