Geopolitical dynamics in Southeast Asia is a complex and interesting theme. This area is strategic, connecting the Pacific Ocean and the Indian Ocean, and is a major trade route. The countries of Southeast Asia include Indonesia, Malaysia, Thailand, the Philippines, Singapore, Vietnam, Myanmar, Cambodia, Laos, and Brunei, each with unique social, political, and economic characteristics. One of the main factors in the geopolitical dynamics of Southeast Asia is the involvement of major powers, especially the United States and China. The two countries compete for influence in the region, raising tensions on the topic of regional stability. China, through the Belt and Road Initiative (BRI) project, seeks to improve economic and infrastructure ties with ASEAN countries, leading to increased economic interdependence. Meanwhile, the United States seeks to strengthen alliances through various defense agreements. This approach can be seen in the “Pivot to Asia” policy which prioritizes military and economic cooperation. In this context, ASEAN as a regional organization plays an important role in facilitating dialogue and cooperation between countries, maintaining stability and reducing tensions. On the other hand, issues such as territorial disputes in the South China Sea continue to be a source of tension. Countries such as Vietnam and the Philippines claim rights to a number of islands and natural resources in the region. This conflict involves China often showing an aggressive attitude in defending its claims, adding to fears of a possible confrontation. Social and cultural aspects also play a role in this dynamic. The ethnic and cultural diversity in Southeast Asia creates its own challenges in establishing unity. Even though there are regional agreements through ASEAN, there are often differences of opinion regarding foreign policy issues. Issues such as human rights, democracy, and sustainable development are major concerns affecting relations between countries. Apart from that, climate change is also an important concern in this region. Southeast Asia is an area that is vulnerable to natural disasters such as floods, storms and rising sea levels. Regional cooperation is needed to face these challenges, formulate adaptive policies, and increase regional resilience to climate change. Along with technological developments, new threats such as cybercrime and terrorism also cast a shadow over stability. Countries in the region realize the importance of cooperation in the field of cyber security to protect critical infrastructure. Training programs and information sharing between countries are needed to build capacity to face these threats. Changes in domestic political dynamics in several countries also influence geopolitics. For example, elections, regime changes, or social conditions can influence foreign policy. The wave of protests in Myanmar and political uncertainty in Thailand show the impact of domestic dynamics on regional stability. With conditions always changing, attention to education and human resources is also key. Investment in education and capacity development is vital to produce a competitive workforce, support sustainable economic growth, and increase bargaining power in global markets. The role of youth is also increasingly important in geopolitical dynamics. The younger generation has a different opinion perspective, is more open to change, and contributes to social movements. Through digital platforms, they can influence political views and policies in Southeast Asia, bringing global issues into local discussions. Looking at the whole picture, geopolitical dynamics in Southeast Asia are a reflection of the complex interactions between international forces, regional issues, and shifts in society. It is important for countries in the region to continue to adapt, develop inclusive strategies, and commit to cooperation to create sustainable stability and prosperity.
