Geopolitics of Southeast Asia in the Era of Globalization Southeast Asia is a strategic region, located at the crossroads of trade routes between the Pacific Ocean and the Indian Ocean. In the era of globalization, the geopolitics of this region are increasingly complex, influenced by global political, economic and social dynamics. Countries in Southeast Asia, such as Indonesia, Malaysia, Thailand and Vietnam, are faced with new challenges and opportunities that affect their relations at regional and international levels. One of the key aspects of geopolitics in Southeast Asia is the large influence of global powers, especially the United States and China. The US continues to strengthen its defense alliance with ASEAN countries, seeking to restrain the expansion of China’s influence through various initiatives, such as the Indo-Pacific Strategy. On the other hand, China has expanded its presence through the Belt and Road Initiative (BRI), which offers infrastructure investment to Southeast Asian countries. Geopolitical tensions in the South China Sea are a major highlight in this context. Some countries, such as Vietnam and the Philippines, have overlapping territorial claims with China, causing tensions that have the potential to disrupt regional stability. Diplomatic efforts through ASEAN must be increased to defuse these tensions, although there are challenges in reaching agreements among member countries with different interests. The Southeast Asian economy is also experiencing significant transformation in the era of globalization. With a large population and growing middle class, the region is attractive for foreign investment. Digitalization and information technology have changed the face of business and commerce. Countries such as Singapore and Indonesia are becoming centers of innovation and startups, attracting the attention of global investors. In addition, regional economic cooperation is increasing through agreements such as RCEP (Regional Comprehensive Economic Partnership), which increases economic integration in the region. Meanwhile, social and cultural issues are no less important. Globalization has brought various cultural influences, but it has also raised questions about national identity. Ethnic and religious tensions, especially in multicultural countries, are challenges that need to be managed. Through constructive intercultural dialogue, ASEAN countries can create social cohesion amidst diversity. Environmental challenges also cannot be ignored in the geopolitical context of Southeast Asia. Climate change and natural disasters threaten natural resources and food security. Cross-border cooperation is essential to address this issue, with a focus on sustainable development. Green initiatives, such as the use of renewable energy and protection of biodiversity, should be a priority on the regional political and economic agenda. As Southeast Asia steps into an increasingly complex era of globalization, it is important for countries in the region to adapt and build inclusive and collaborative strategies. Multilateral diplomacy needs to be strengthened to face common challenges, while innovation and the digital economy are the main drivers of growth. By leveraging its rich resources and cultural diversity, Southeast Asia has the potential to become a key player on the world stage. Sustainability, peace and cooperation are the keys to building a better future for the region.
