Recent developments in Southeast Asian geopolitics show very interesting and complex dynamics. This region is the center of world attention, especially because of its strategic position on global trade routes and the existence of various large powers competing for influence. One major factor is rising tensions between the United States and China. The US is trying to strengthen military and economic cooperation with Southeast Asian countries through programs such as the Indo-Pacific Strategy. On the other hand, China continues to expand its influence through the Belt and Road Initiative (BRI) project, which offers infrastructure and investment in ASEAN countries. This created a shift in bargaining power between the smaller countries in the region, which tried to balance their relations with the two great powers. Apart from that, the South China Sea conflict remains an issue that disrupts regional stability. Countries such as Vietnam and the Philippines are strengthening their armed forces to counter China’s territorial claims. In the midst of this tension, Indonesia acts as a mediator by proposing a peaceful resolution through multilateral dialogue. This approach reflects Indonesia’s active foreign policy, emphasizing the importance of cooperation and peaceful resolution. Economics is also an important aspect of Southeast Asian geopolitics. Post-COVID-19 pandemic recovery provides an opportunity for ASEAN countries to collaborate more closely. The formation of the ASEAN economic community (AEC) aims to increase trade and investment between countries, although regulatory obstacles are still a challenge. The presence of a growing market and young workforce provides more attraction for foreign investors. Meanwhile, issues related to climate change and food security are increasingly dominating the geopolitical agenda in the region. ASEAN countries are committed to addressing the impacts of climate change through various initiatives, including the development of renewable energy and protection of biodiversity. By collaborating on disaster mitigation and responding to extreme climates, Southeast Asian countries are showing that they can unite in facing this global challenge. Competition for access to natural resources, especially in waters and tropical forests, is also a focus of attention. Negotiations on resource management rights often involve multiple actors, including multinational companies and international donor agencies. Changing strategies in environmental management is important to maintain sustainability and reduce conflict. Social disintegration and the rise of populist movements are also worth paying attention to. Internal conflicts in several countries, such as Myanmar, show how instability can affect relations between countries in the region. Civil society is increasingly playing a role in pushing for reform and fighting for human rights, which has an impact on developments in domestic politics and foreign relations. Technological aspects such as cyber and digitalization have become key in geopolitical interactions. Countries in Southeast Asia are starting to strengthen cyber capabilities, considering growing security threats. Investment in information and communications technology (ICT) is a priority, with the hope of increasing competitiveness on the global stage. In this context, the Asean Regional Forum (ARF) and other multilateral institutions seek to create collective action to handle complex issues. Discussions regarding cyber security, terrorism, and weapons proliferation are also receiving greater attention in the hope of creating mechanisms to respond to common threats. From socio-political dynamics to economic and environmental challenges, Southeast Asia’s rich history and culture continue to shape the region’s geopolitics. With the various initiatives taken, both unilaterally and multilaterally, countries in Southeast Asia have the potential to shape a new direction in global geopolitics, making it important for international observers to pay attention to.
