ADB Report: AI Set to Widen Asia's Growth Gap as Readiness Divides Deepen

The Asian Development Bank has put numbers on what many policymakers feared. Its April 2026 Asian Development Outlook report reveals that artificial intelligence is accelerating economic growth in Asia's advanced economies while threatening to leave developing nations further behind. The readiness divide is not narrowing; it is widening.

The data is stark. Countries with strong AI infrastructure, talent pipelines, and regulatory frameworks stand to gain 1.5 to 2.5 percentage points of additional GDP growth annually through 2030. Those without risk falling behind by an equivalent margin, creating a compounding gap that could reshape Asia's economic hierarchy within a decade.

The Readiness Divide in Numbers

The ADB's AI Readiness Index ranks 45 Asian economies across four dimensions: infrastructure, talent, governance, and innovation ecosystem^✦. The results reveal a continent splitting into three distinct tiers.

The concentration of AI capability is extraordinary. China, Japan, South Korea, Singapore, and India account for nearly nine in ten commercial AI patents filed across the continent. The remaining 40 economies share the rest, and many have fewer AI researchers than a single university department in Seoul or Beijing.

Infrastructure: The Foundation Gap

The ADB estimates a USD 1.2 trillion cumulative investment gap in digital infrastructure across developing Asia. This is not just about data centres, although those matter. It encompasses reliable electricity, broadband connectivity, cloud computing capacity, and the technical standards that allow AI systems to operate at scale^✦.

The AI readiness divide is fundamentally an infrastructure divide. Without reliable power and connectivity, the most brilliant algorithm in the world sits on a shelf.

Singapore and South Korea have near-universal broadband and world-class^✦ data centre capacity. Cambodia and Myanmar remain below 30% broadband penetration, with data centre capacity measured in single facilities rather than clusters. Cambodia's own digital foundations strategy acknowledges this gap explicitly, but closing it requires investment that far exceeds current budget allocations.

The infrastructure gap compounds over time. Countries that cannot offer reliable cloud computing today will struggle to attract AI companies tomorrow, which means less tax revenue, fewer skilled jobs, and even less capacity to invest in infrastructure.

Talent: Concentration and Brain Drain

The talent picture is equally concerning. The ADB identifies a 7:1 ratio in AI researchers per capita between Asia's most and least prepared economies. Worse, brain drain pulls talent from developing countries toward Singapore, Seoul, and the tech hubs of China's vertical AI ecosystem.

• South Korea produces roughly 128 AI researchers per million people; Myanmar produces approximately one
• Salary differentials of 5-10x between Tier 1 and Tier 3 economies make retention nearly impossible
• Microsoft's teacher training programme in India represents one approach to building pipeline capacity, but such initiatives remain the exception

You cannot build an AI economy by importing talent. You must grow it domestically, and that requires investment in education systems that most developing Asian countries have not yet made.

The ADB recommends that developing economies prioritise AI literacy programmes at the secondary education level rather than competing directly for PhD-level researchers, an approach that Gulf states have begun implementing with notable early results.

Policy Fragmentation Across the Region

Governance adds another layer of complexity. While Malaysia moves from guidelines to legislation and Vietnam implements Southeast Asia's first standalone AI law, most developing Asian economies lack even basic AI governance^✦ frameworks. The ADB report notes that only 12 of 45 surveyed economies have published national AI strategies, and fewer than half of those have allocated dedicated funding.

This creates regulatory uncertainty that discourages both domestic innovation and foreign investment. Companies prefer jurisdictions with clear rules, even strict ones, over those where the regulatory landscape is undefined.

The broader debate about AI governance in Asia increasingly centres on whether regional coordination through ASEAN, SAARC, or bilateral arrangements can bridge the gap faster than individual national efforts.

What Must Change

The ADB identifies three critical intervention areas:

1. Targeted infrastructure investment: prioritising broadband and cloud capacity in underserved economies rather than spreading funding thinly across all sectors
2. Regional talent mobility frameworks: allowing AI professionals to work across borders while maintaining incentives for return migration
3. Harmonised governance standards: developing minimum regulatory baselines that reduce compliance complexity for companies operating across multiple Asian jurisdictions

Without coordinated action, the report warns, AI will amplify existing inequalities rather than reduce them. The digital sovereignty concerns already visible in Central Asia could spread across Southeast Asia as countries weigh dependence on foreign AI infrastructure against the cost of building their own.
