EU AI Act + Global AI Regulation in 2026 — What Thai Businesses Need to Know

If you are a Thai business executive deploying AI — whether it is a chatbot, a resume screening system, AI embedded in your ERP, or generative AI tools your team uses daily — 2026 is the year you can no longer treat "AI regulation" as someone else's problem.

The most comprehensive AI legislation in the world is reaching full enforcement, and its impact extends far beyond European borders.

EU AI Act — The World's First Comprehensive AI Law

The EU AI Act was officially signed into law in August 2024. It is the first legislation anywhere in the world to establish a complete regulatory framework for AI — from development and deployment to governance and enforcement.

The cornerstone of this law is a Risk-Based Approach, meaning AI systems posing higher risks face stricter requirements, while low-risk applications remain largely unregulated.

Enforcement Timeline — The Deadlines Keep Coming

The law does not take effect all at once. Instead, it rolls out in waves:

February 2025 — Prohibited AI Practices Banned

AI systems classified as "unacceptable risk" were completely banned as of February 2, 2025. This phase also introduced AI literacy requirements for developers and deployers.

August 2025 — GPAI Obligations Begin

Starting August 2, 2025, providers of General-Purpose AI Models (GPAI) placed on the market after this date must comply with new obligations. This includes large-scale models like GPT, Claude, and Gemini. Models deemed to pose systemic risks must notify the EU AI Office.

August 2026 — Full Enforcement

This is the critical deadline — August 2, 2026. Requirements for high-risk AI systems take full effect, along with the European Commission's enforcement powers, including the ability to impose fines.

August 2027 — Legacy GPAI Deadline

GPAI models placed on the market before August 2025 must achieve compliance by August 2, 2027.

The Four-Tier Risk Classification — The Heart of the EU AI Act

The EU AI Act categorizes AI systems into four risk levels, each determining the degree of regulatory oversight:

Tier 1: Unacceptable Risk — Banned Entirely

AI systems that contradict fundamental EU values are prohibited outright:

• Social scoring systems that evaluate citizens' behavior
• AI using subliminal or manipulative techniques to distort behavior
• Real-time biometric identification in public spaces (with narrow exceptions for security)
• Predictive policing based on personal profiling data

Tier 2: High Risk — Strict Compliance Required

AI used in areas with significant impact on people's lives must undergo conformity assessments before deployment:

• Critical infrastructure — Energy management, traffic control, water supply systems
• Education and training — AI that determines grades or screens students
• Employment — AI that screens resumes, evaluates performance, or decides terminations
• Financial services — AI credit scoring, fraud detection
• Justice and law enforcement — AI assisting in court decisions or risk assessments

Requirements for high-risk AI include: risk assessment, data quality standards, technical documentation, transparency, human oversight, and accuracy benchmarks.

Tier 3: Limited Risk — Disclosure Required

AI systems that interact with users must inform them they are engaging with AI:

• Chatbots must disclose they are AI-powered
• AI-generated content (such as deepfakes) must be labeled
• AI-driven decisions must be explainable

Tier 4: Minimal Risk — No Additional Requirements

Most everyday AI applications fall here — spam filters, AI in games, product recommendation engines. No additional regulatory obligations apply.

How Does This Affect Thai Businesses?

"We are not in Europe — why should we care?" This is a question we hear often. The answer is clear:

Extraterritorial Reach

Like GDPR before it, the EU AI Act applies outside EU borders in these scenarios:

• Thai businesses serving EU customers — If you use AI in products or services sold to EU customers, you must comply
• Thai businesses using AI output in Europe — If your AI's output is used within the EU, you fall under this law
• Thai businesses in EU supply chains — If your European clients must comply with the EU AI Act, they will require their entire supplier chain to comply as well

AI in ERP and Business Systems

A blind spot many organizations overlook is AI embedded in ERP and business software:

• AI in HR systems — Resume screening with AI may qualify as High Risk
• AI in credit systems — AI-based credit scoring requires bias auditing
• AI in supply chain — Demand forecasting that affects employment or critical infrastructure may fall under High Risk
• Customer service chatbots — Must disclose they are AI under Limited Risk requirements

Choosing an ERP system with built-in AI compliance is becoming critically important from 2026 onward.

Global AI Regulation — It Is Not Just the EU

United States — Pro-Innovation Approach

The US has taken a distinctly different path from the EU:

• January 2025 — Executive Order 14179 revoked the 2023 Executive Order on AI safety, shifting policy toward promoting innovation and US AI leadership
• December 2025 — A new Executive Order challenged state-level AI laws that might impede innovation, directing the Attorney General to establish an AI Litigation Task Force
• The US approach favors self-regulation over binding legislation

Despite the lighter touch, businesses seeking access to both US and EU markets will need to meet the stricter standard — which is the EU AI Act.
