The geopolitical dynamics of Southeast Asia in the era of globalization displays increasing complexity. This area has become the center of world attention, given its strategic position and diversity of natural and cultural resources. In this context, a number of factors influence these dynamics, including economic growth, regional conflicts, and the influence of major powers such as the United States and China. Southeast Asia’s rapid economic growth is one of the main drivers of geopolitical dynamics. In the last two decades, countries in the region have experienced significant GDP growth. Countries such as Indonesia, Vietnam and the Philippines are showing impressive achievements, attracting foreign investment and creating job opportunities. This makes Southeast Asia one of the regions with the fastest economic growth in the world, which further increases its political bargaining power on the international stage. On the other hand, territorial tensions in the South China Sea illustrate the challenges facing Southeast Asian countries. This issue involves overlapping claims by several countries, including China, Vietnam and the Philippines. This dispute threatens regional stability and affects diplomatic relations between countries. China’s use of military force and infrastructure development in the area creates tensions that can affect national security in small countries. The influence of the United States in Southeast Asia is also very significant. As part of its Indo-Pacific strategy, the US seeks to maintain its presence in the region to balance China’s power. Military cooperation with ASEAN countries, such as joint exercises and arms sales, is an effort to strengthen strategic alliances and maintain stability. Southeast Asia is also faced with various social and economic issues, including income inequality, poverty and human rights issues. These issues not only affect the internal stability of countries, but also affect the region’s reputation in the eyes of the world. The government needs to implement inclusive policies to ensure sustainable economic growth and reduce social tensions. Climate change is another challenge that cannot be ignored. Countries in Southeast Asia are very vulnerable to the impacts of climate change, such as rising sea levels and natural disasters. This requires international cooperation in handling it, as well as a commitment to sustainable development. Multilateral cooperation through ASEAN plays an important role in dealing with these various challenges. ASEAN seeks to create stability through dialogue and diplomacy, although it is often faced with challenges in reaching agreements among its members who have different interests. Strengthening the economic, social and political pillars within ASEAN is expected to increase the region’s adaptability to global change. With increasing digitalization and information interconnection, Southeast Asia is also experiencing transformation in social and economic aspects. The digital revolution allows countries in the region to innovate and compete in global markets, creating new opportunities for startups and industry. However, challenges in terms of digital skills and infrastructure still need to be overcome to ensure all countries can enjoy these benefits. The geopolitical dynamics of Southeast Asia in the era of globalization reflect complex interactions between economic growth, regional security and social issues. In facing these challenges, a collaborative and innovative approach is needed to create a safe, stable and prosperous region. Strengthening relations between countries in the region and commitment to international cooperation will be critical to achieving this goal.
