The dynamics of power change in Southeast Asia reflect complex interactions between politics, economics and culture. Since the late 20th century, the region has witnessed significant transformation driven by several factors, including globalization, shifts in economic power, population growth, and developments in information technology. One of the main indicators of a change in power is the rise of China as a major economic power. Through the Belt and Road initiative (BRI), China is expanding its influence in Southeast Asia, offering massive infrastructure investments. This fueled economic growth, but also created dependency on Beijing in regional countries, such as Laos and Cambodia. Apart from that, political changes in ASEAN countries also play an important role. For example, Thailand and the Philippines experienced various political crises that resulted in regime changes. In this context, elections that are often influenced by internal conflicts and public protests change the political landscape. In the Philippines, the presence of Rodrigo Duterte and his controversial policies are creating a new wave in the way the government operates. On the other hand, countries such as Vietnam, which adopted a market socialism model, demonstrated strong economic growth. Vietnam is trying to balance relations with the two big powers, namely the US and China, while maintaining political independence. This success can also be seen from the increase in foreign investment and rapidly increasing exports. From a social perspective, the emergence of a larger middle class in Southeast Asia is contributing to changes in consumption patterns and political aspirations. This group is more critical of the government and active in supporting human rights and transparency. Social media plays an important role in facilitating dialogue and community mobilization, giving a voice to a mature generation of young people. In addition, regional issues such as maritime security and territorial disputes, especially in the South China Sea, create geopolitical tensions. Countries such as Vietnam and the Philippines are strengthening their armed forces in response to China’s increasingly aggressive claims, signaling an adjustment in security strategies in the region. Climate change is also reconfiguring power dynamics, forcing Southeast Asian countries to adapt and collaborate in finding sustainable solutions. In addition to national strategies, regional cooperation initiatives such as ASEAN seek to build awareness and preparedness for the impacts of climate change, with a focus on sustainable development and disaster mitigation. Global uncertainty, including the impact of trade wars and the COVID-19 pandemic, has accelerated changes in foreign policy. Countries in this region are more careful in forming alliances and trying to balance relations with major powers. In this context, a more inclusive and participatory vision is increasingly prioritized in regional diplomacy. Thus, the dynamics of power change in Southeast Asia are multidimensional and continue to develop. Through a deep understanding of the political, economic and social context, we can see how countries in the region are adapting to face future challenges and create stronger ties between them.
