The latest developments in US-China diplomacy are increasingly attracting global attention, considering the role of the two countries as major powers that influence many aspects of world geopolitics, economics and security. Relations between the US and China have entered a complicated phase, with various initiatives and trends visible in recent years. One of the main issues in this diplomacy is trade disputes. Since 2018, the US administration has imposed high tariffs on Chinese products, which has led to a similar response from the Chinese side. However, in 2021, there appears to be an attempt to return to the negotiating table. Several rounds of negotiations took place, although concrete results often fell short of expectations, creating uncertainty in global markets. Apart from trade, technology is also one of the main focuses in this relationship. The rise of advanced technology in China, such as artificial intelligence and 5G, has sparked concerns in the US, which believes China’s technological dominance could threaten national security. Initiatives such as the Clean Network and restrictions on investment in Chinese technology companies are steps by the US to maintain its technological edge. The issue of climate change has also become a new meeting point in US-China diplomacy. Both countries are the world’s largest emitters and there is an agreement to work together to tackle climate challenges. A 2021 summit led by the leaders of the two countries resulted in commitments to reduce emissions and invest in renewable energy. Despite some bright spots, tensions remain. The Taiwan issue, which is a red line for China, continues to be a source of conflict. The US supports Taiwan diplomatically and militarily, while China asserts its right to take back the territory. Increasingly intense military exercises around the Taiwan Strait show the extent of these tensions. In multilateral terms, the two countries also compete and collaborate in international forums. For example, at the G20 forum, both play a role in determining global economic policy. However, in the context of more specific agreements, such as ASEAN, differences of opinion often occur, exposing the competitive side of this relationship. Diplomatic visits between high-ranking officials from both countries, such as foreign ministers and ambassadors, are an effort to ease tensions. Although this dialogue is important, many doubt its effectiveness given the tenacity of each side in defending their core positions. Recent developments in US-China relations are also influenced by the domestic situation of each country. In the US, identity politics and public views of China are increasingly polar. On the other hand, China is focused on regaining its status as a global power post-COVID-19 pandemic, seeking to strengthen its influence in Asia and Africa through the Belt and Road Initiative. Changes in leadership in both countries may also have a significant impact on diplomatic approaches. The US led by Biden wants a more cooperative approach, while China under Xi Jinping continues to show a firm stance in foreign policy. Given these dynamics, future developments in US-China relations will continue to be in the world’s spotlight, with far-reaching impacts on the entire international community.
