The geopolitical dynamics between the US and China are increasingly heating up, creating significant global anxiety. Relations between these two countries are filled with various issues, from trade to technology and defense. Economic competition is one of the main aspects of these tensions, with China continuing to grow as a major economic power challenging US dominance. With its “Made in China 2025” policy, China is seeking to become a leader in high-tech industries, sparking concern in Washington. On the other hand, China’s militarization of the South China Sea also plays an important role in this dynamic. China claims almost the entire sea, despite resistance from Southeast Asian countries and the US, which supports freedom of navigation. These tensions have only increased with the increasing US military presence in the region, including joint exercises with allies such as Japan and Australia. The Taiwan issue is also a major source of tension. China considers Taiwan to be part of its territory and is committed to unifying it, while the US adheres to the “One China” policy while still supporting the island’s defense. Increased US support for Taiwan also has the potential to trigger a reaction from Beijing, which has threatened to take military action if necessary. In technology, competition in innovation and information security is creating deeper dividing lines. The trade war that started in 2018 had a significant impact on the economies of both countries. The US imposes high tariffs on Chinese goods and imposes restrictions on technology companies such as Huawei. These actions aim to protect US national interests and slow China’s technological progress. Meanwhile, multilateral diplomacy is also a critical tool for both countries. The US is strengthening alliances with countries such as India and NATO in response to China’s rise. On the other hand, China is trying to expand its influence through the Belt and Road Initiative, by offering large investments in developing countries to build mutually beneficial economic relations. Global crises, such as the COVID-19 pandemic, exacerbate these tensions. The US accused China of hiding important information about the virus, while China claimed that the US was diverting attention from its internal issues. This uncertainty breeds deep distrust, making diplomacy more difficult to achieve. In the midst of this tension, international forums such as the UN have become an important arena for dialogue. However, this mechanism is often caught in political deadlock. Both countries have significant influence in international institutions, but friction often occurs, especially on issues such as human rights or climate change. Post-pandemic economic recovery is another pressure point. Both countries are seeking to dominate the global economic recovery, creating unhealthy dependency. Uncertainty about supply chains and inflation has made each country’s strategic focus shift to investment alternatives and new markets. In facing this challenge, it is important for countries in the region to find a balance between cooperation and competition. Diplomacy must be implemented carefully to avoid wider conflict. While US-China tensions continue, their impact is being felt around the world, influencing the policies and positions of other countries in confronting these two giants.
