The geopolitical dynamics of Southeast Asia in the digital era have undergone significant transformation. This region, which is located at the crossroads of international trade routes, is now faced with new challenges and opportunities due to developments in information technology. The rapid growth of the internet and smartphone use is contributing to profound socio-political changes. One important aspect is the shift in economic power. Countries such as Indonesia, Malaysia and Vietnam are increasingly becoming centers of digital innovation and investment. With a young population connected online, they are driving the growth of the e-commerce and financial technology sectors. This has led to these countries playing a key role in global supply chains, attracting the attention of major powers such as the United States and China. When talking about geopolitics, it cannot be separated from cyber security issues. Countries in Southeast Asia face threats from cyber attacks that impact political and economic stability. With increasing tensions between global powers, the race for control of the digital space is a strategic stake that cannot be ignored. Therefore, collaboration between countries in the field of cyber security is increasingly important, strengthening regional alliances such as ASEAN to develop security protocols. Social media also plays an important role in political dynamics. Platforms such as Facebook and Twitter not only facilitate public discussion but are also used for political campaigns and mass mobilization. However, the existence of fake news and disinformation is a challenge in itself, threatening the stability of democracy in several countries. The government is required to adapt quickly to this reality through appropriate regulations, without sacrificing freedom of expression. In the digital era, economic competitiveness is also determined by the ability to innovate. Countries like Singapore are leading the way in creating startup ecosystems that support technology development. Investment in STEM (science, technology, engineering and mathematics) education is becoming a major focus to prepare future generations to face global challenges. Through this initiative, Southeast Asia seeks to become a more competitive technology hub. Additionally, reliance on technology also brings attention to issues such as data privacy and human rights. Strict policies are needed to protect users from data misuse amidst increasing digital attacks. Countries in Southeast Asia need to build a comprehensive legal framework to respond to these issues more effectively. Climate change is also an important part of the geopolitical dynamics in this region. Digital technology offers innovative solutions to environmental challenges, such as weather monitoring and natural resource management. International cooperation in the field of green technology is important, enabling Southeast Asian countries to contribute to global efforts to mitigate climate change while maintaining economic growth. Finally, it is important to note that despite the challenges, the digital era also provides opportunities to enhance multilateral cooperation. Joint initiatives in technology, economics and security can bring Southeast Asian countries closer together, creating a more stable and prosperous future. Thus, the geopolitical dynamics of Southeast Asia in the digital era are not just a challenge, but also an opportunity to develop a strong regional identity.
