ASEAN’s digital economy could reach as much as $2 trillion by 2030 if member states successfully implement the newly concluded ASEAN Digital Economy Framework Agreement, or DEFA. ASEAN Secretary General Kao Kim Hourn highlighted the potential during the 2026 DEFA Foresight and Strategic Cooperation Pre Summit Forum in Hong Kong on September 7, as the region moves closer to signing the landmark agreement.
The opportunity is particularly relevant for Cambodia, where digital payments, e commerce, technology services and cross border trade are becoming increasingly important to businesses and consumers. DEFA covers digital trade, e commerce, payments, digital identities, cybersecurity, cross border data flows, competition policy, emerging technologies and talent mobility, potentially creating a more integrated digital market across ASEAN.
“ASEAN is entering a decisive phase in its digital transformation, with DEFA providing a framework for deeper regional integration and a potentially much larger digital economy by 2030. The agreement is designed not simply to increase digital transactions, but to reduce regulatory and technical barriers that make cross border business more expensive and complicated. For Cambodia, this could create new opportunities for startups, online businesses, exporters, fintech companies and technology investors to reach customers and partners across the region. At the same time, stronger rules around data, cybersecurity, digital identity and consumer protection mean businesses will need to adapt to a more connected and regulated digital environment. The success of DEFA will ultimately depend on implementation and the ability of businesses across ASEAN to turn regional digital integration into practical commercial opportunities.”
ASEAN Moves Toward a More Integrated Digital Economy
ASEAN’s digital economy generated around $305 billion in gross merchandise value in 2025 and is projected to reach approximately $1 trillion by 2030 under current trends. According to Kao Kim Hourn, effective implementation of DEFA could potentially double that figure to $2 trillion.
The negotiations concluded in May 2026, resolving the remaining issues and marking a major milestone for ASEAN’s first region wide digital economy agreement. Member states are now moving through their domestic processes before the agreement is expected to be signed at the 49th ASEAN Summit in November.
The importance of DEFA lies in its regional scope. Rather than addressing individual digital issues through separate national systems, the framework is designed to create greater interoperability and reduce differences that make digital commerce across borders more complicated.
DEFA Could Lower Barriers for Cambodian Businesses
For Cambodian companies, one of the biggest potential advantages is easier access to regional markets. Small businesses, startups and digital entrepreneurs often face regulatory, payment and technical barriers when attempting to sell products or services outside Cambodia.
Kao Kim Hourn said DEFA’s success should not be measured only by the value of digital transactions. Its broader purpose is to reduce regulatory and technical barriers to cross border business while helping micro, small and medium sized enterprises expand regionally and reduce costs. This is particularly significant for Cambodia because smaller businesses make up a substantial part of the domestic economy and increasingly use digital platforms to reach customers.
The framework could therefore support Cambodian businesses seeking customers in neighbouring ASEAN markets, while also making it easier for regional companies to engage with Cambodia. The opportunity extends beyond e commerce to logistics, financial technology, professional services, software, tourism technology and other digitally enabled sectors.
Paperless Trade Could Make Cross Border Commerce Easier
DEFA builds on existing ASEAN digital integration initiatives, including the ASEAN Single Window. The system has already processed more than 7 million ATIGA e Form DS2 documents, generating estimated savings of $1 billion and 43 million days, according to the information presented by ASEAN.
DEFA is expected to advance paperless trade through measures covering electronic signatures, electronic invoicing, consumer protection and data governance. For businesses involved in international trade, reducing paperwork and improving digital interoperability could lower administrative costs and make transactions faster.
For Cambodia, stronger digital trade infrastructure could complement the country’s growing participation in regional supply chains. Exporters and importers that adopt compatible digital systems may find it easier to exchange documents, manage transactions and work with partners in other ASEAN markets.
Digital Payments Could Create New Opportunities
Digital payments are another major part of ASEAN’s digital transformation. Adoption reached 61 per cent of transactions in 2025 and is forecast to rise to 73 per cent by 2030.
The region already has 29 bilateral QR payment linkages with partners including China, Japan, India, Hong Kong and South Korea. This growing payment connectivity could support businesses that serve international customers, particularly tourism, retail, hospitality and online commerce.
For Cambodia, where QR based payments have become increasingly visible in everyday commerce, broader regional interoperability could make cross border transactions more convenient. Tourists and businesses could benefit from payment systems that work more seamlessly across markets, while Cambodian merchants could potentially gain easier access to regional customers.
Data and Cybersecurity Will Become More Important
Greater digital integration also brings greater responsibility around data protection and cybersecurity. Kao Kim Hourn stressed the importance of trusted cross border data flows, stronger privacy safeguards and cybersecurity cooperation, including through the ASEAN Regional Computer Emergency Response Team.
For Cambodian businesses expanding digitally, this means regional growth will increasingly require attention to data governance and security. Companies that collect customer information, process online payments or transfer data across borders will need to operate in an environment where trust and protection become increasingly important to digital commerce.
The cybersecurity component is especially significant because greater interoperability can increase both opportunity and exposure. A more connected regional economy requires businesses and governments to strengthen their ability to prevent, detect and respond to digital threats.
Emerging Technology and Talent Are Part of the Framework
DEFA also addresses emerging technologies and talent mobility, reflecting the rapid changes taking place across ASEAN’s digital economy. Kao Kim Hourn said ASEAN aims to accelerate the adoption of emerging technologies while ensuring that development remains safe, inclusive and responsible.
For Cambodia, this could create opportunities for technology startups, digital service providers and skilled professionals. Greater regional integration could make it easier for companies to collaborate across borders and for talent to participate in a broader digital economy.
Skills development will therefore be increasingly important. As digital businesses expand beyond national markets, companies will need professionals who understand technology, cybersecurity, digital commerce, data governance and regional business practices.
Cambodia Has a Strategic Opportunity in ASEAN’s Digital Growth
Cambodia stands to benefit from DEFA if its businesses are prepared to operate within a more integrated regional digital market. The opportunity is not limited to large technology companies. Small retailers, online sellers, tourism businesses, fintech firms, startups and professional service providers could all benefit from easier regional connectivity.
The challenge will be turning the agreement into practical results. Businesses will need to understand new digital rules, upgrade their systems, protect customer data and develop products that can compete beyond Cambodia. Government agencies and industry stakeholders will also have an important role in supporting digital infrastructure, skills development and regulatory readiness.
The $2 Trillion Goal Depends on Implementation
ASEAN has completed an important stage of the DEFA process, but the agreement’s economic impact will ultimately depend on implementation. ASEAN’s own statement describes effective implementation as critical to unlocking the potential of a digital economy that could reach as much as $2 trillion by 2030.
For Cambodia, the message is both an opportunity and a challenge. A more connected ASEAN digital economy could give Cambodian companies access to larger markets, faster payment systems, more efficient digital trade and new technology partnerships. At the same time, businesses will face stronger expectations around cybersecurity, data protection, digital skills and competitiveness.
The broader takeaway is that ASEAN’s digital integration is moving from policy discussion toward implementation. For Cambodian entrepreneurs and investors, preparing early could be more valuable than waiting until the new regional digital environment is fully established.
