Economic cooperation within ASEAN (Association of Southeast Asian Nations) has a very crucial role in increasing economic growth and stability in this region. In facing global challenges, such as climate change, pandemics and increasingly fierce economic competition, collaboration among ASEAN countries is more important than ever. One concrete form of this economic cooperation is through the ASEAN Economic Community (AEC). AEC aims to create a single market and competitive production base in the region, thereby facilitating the movement of goods, services, investment and skilled labor. With the existence of the AEC, it is hoped that it can increase intra-ASEAN trade and encourage greater investment, creating new jobs. Other economic initiatives include the ASEAN Free Trade Area (AFTA), which reduces trade tariffs between ASEAN member countries. This not only increases market access, but also encourages companies to invest and develop local products, thereby increasing competitiveness. Countries such as Indonesia and Vietnam have felt the positive impact of these tariff reductions, with significant increases in exports. Economic cooperation in ASEAN also includes infrastructure development. Many member countries are uniting to build more efficient transportation and communications networks. Projects such as the Master Plan on ASEAN Connectivity 2025 aim to strengthen physical, institutional and people-to-people connectivity in the region. Good infrastructure is essential to support sustainable economic growth and reduce logistics costs. The importance of cooperation in the fields of technology and innovation cannot be ignored. ASEAN countries seek to collaborate in research and development, especially in the information and communications technology (ICT) sector. By sharing knowledge and resources, ASEAN countries can accelerate the adoption of new technologies, stimulate innovation, and drive the growth of the digital economy with great potential. The digital economic transformation in this region also provides opportunities for SMEs (Small and Medium Enterprises) to grow. Programs such as the ASEAN SME Policy Index focus on developing policies that support SMEs to access regional and global markets, increasing their capacity to compete. ASIA also collaborates with partner countries such as China, Japan and South Korea to strengthen trade and investment networks. This partnership not only brings economic benefits, but also creates a platform for sharing technology and experience in addressing modern challenges such as climate change and food security. Global crises such as the COVID-19 pandemic show the importance of solidarity between ASEAN countries. Cooperation in vaccine distribution and economic support for recovery demonstrate member countries’ commitment to supporting each other in difficult situations. In the future, ASEAN is expected to be able to build better resilience through closer economic collaboration. Economic cooperation within ASEAN is not just about increasing growth rates. It is also about creating a more inclusive and sustainable future for all people in the region. With a collaborative approach, ASEAN countries can face existing challenges and take advantage of emerging opportunities, making the Southeast Asia region one of the main economic powers in the world.
