Rising Sino-US Tensions in Global Diplomacy In recent years, tensions between China and the United States (US) have increased significantly, affecting the dynamics of global diplomacy. The competition between these two countries covers various aspects, including trade, technology, security and geopolitics. These tensions not only impact bilateral relations, but also create wider waves of impact for countries around the world. One of the most striking aspects of these tensions is the trade war that began in 2018. The high tariff policy imposed by the US on Chinese goods resulted in retaliation in the form of tariffs from the Chinese side. This conflict shows how interconnected the global economy is, with many third countries caught in the middle. International companies face challenges in supply chains, resulting in economic uncertainty around the world. In the realm of technology, the two countries compete fiercely to become leaders in innovation. China is investing heavily in 5G technology and artificial intelligence, while the US is trying to prevent Chinese companies from accessing advanced technologies. A clear example of this is the ban on companies such as Huawei, which is considered a threat to US national security. These tensions strengthen support for domestic technology development, but also create dilemmas for other countries that depend on products and services from both countries. The security sector is also a main focus in this conflict. The US military presence in the Asia-Pacific region and the spread of China’s maritime power in the South China Sea add to tensions. The US claims that its presence aims to maintain freedom of navigation, while China sees it as a challenge to its sovereignty. Territorial disputes in the South China Sea and Taiwan have also been a source of long-standing tension, with both countries seeking to strengthen their positions. From a geopolitical perspective, China has sought to expand its influence through initiatives such as the Belt and Road Initiative (BRI), which aims to improve economic ties and infrastructure with countries around the world. The US, in response, has tried to build new alliances, including the Quadrilateral Security Dialogue (Quad) with Japan, India, and Australia, to balance China’s power. This multilateral diplomacy shows the efforts of both parties to gain global support. Climate change is also a competitive issue that is no less important. Both countries are the world’s largest emitters and have a big responsibility in global efforts to tackle global warming. Even though they have the same interest in reducing the impacts of climate change, diplomatic patterns are often hampered by existing tensions. Cooperation in the environmental sector requires long-term commitment and a win-win approach, which is currently difficult to achieve. The role of social media and information is also very crucial in Sino-US tensions. Propaganda, disinformation and political influence carried out by both parties increasingly confuse the public. In this context, it is important for the public to understand the narrative that is being built and its effect on foreign policy. Rising Sino-US tensions in global diplomacy are creating complex challenges for countries around the world. This is reshaping the international order and influencing how states interact with each other. In the future, a diplomatic solution is needed to reduce these tensions so that the world can achieve greater stability and prosperity.
