Major IEAT free zones: Laem Chabang, Map Ta Phut, Hi-Tech, Bangkok, EEC clusters. Bonded warehouse separately under Customs Department for re-export trade. Used for Thai contract-manufacturing, regional-distribution, and re-export businesses.

Questions this report answers

What's the FTZ structure? Per IEAT and Customs Act Section 152: Thailand offers two parallel free-zone vehicles. IEAT Free Zones embedded in major Thai industrial estates; Customs Department FTZs under Customs Act Section 152. Both defer import duty and VAT.[, ]

What's the BOI, FTZ stack? Per BOI guidance: BOI investment-promotion can be stacked with FTZ status for combined customs-VAT-CIT savings. Operative for Thai contract-manufacturing, regional distribution centres, e-commerce cross-border fulfilment, and re-export trade.[]

Where are major FTZ clusters? Laem Chabang FTZ (auto, electronics, port-adjacent), Map Ta Phut (petrochemical), Hi-Tech Industrial Estate, Bangkok Free Zone, multiple EEC clusters. EEC FTZ designation expanding through 2026-2028.[]

ASEAN AEC Corridor: Cross-Border Investment Flow

ASEAN formally established the ASEAN Economic Community (AEC) in 2015 with the goal of a single market and production base. The AEC Blueprint 2025 targets seamless movement of goods, services, investment, capital, and skilled labor within ASEAN. Per AMRO Asia: intra-ASEAN trade has hovered around 20-25% of total trade for two decades β€” roughly half the level seen between ASEAN and its closest partners (China, Japan, South Korea); intra-ASEAN investment is at only ~10% of total FDI stock and remains relatively shallow. The ASEAN Business Advisory Council estimates USD 80-240B in potential intra-ASEAN trade growth driven by interoperable identity and seamless cross-border onboarding. Within manufacturing, Thailand and Vietnam dominate ASEAN automotive and electronics exports per RSIS analysis. Thailand's role in long-term ASEAN agenda-setting has been periodically constrained by domestic political uncertainty; the more uncertain external environment, narrowing market options, and stronger Chinese economic pressure may create greater incentives for Bangkok to become more ASEAN-centred in advancing the AEC through ASEAN Community Vision 2045. Singapore is the largest intra-ASEAN FDI source for Thailand (305 projects / THB 357.5B in 2024 per BOI).

Aranyaprathet: Cambodia-Border Cross-Trade and SEZ Economics

Aranyaprathet (Sa Kaeo province) is Thailand's primary Cambodia-border crossing to Poipet β€” the dominant land-border node for Thai-Cambodia trade-and-tourism flows. Thai-Cambodia bilateral relations carry persistent border-tension dynamics: periodic Preah-Vihear territorial disputes flare into trade-and-tourism disruption episodes (2008, 2011, 2025), with diplomatic and economic spillover effects. Cambodian migrant workers form a major source of low-skill labour in Thailand across construction, agriculture, hospitality, and fisheries β€” Cambodian migrants concentrate in eastern-Thai provinces and Bangkok metro. Aranyaprathet-Poipet cross-border logistics sit under the ASEAN-China FTA bilateral framework with tariff treatment supporting low-friction merchandise flow. BOI's Sa Kaeo SEZ incentives anchor a cross-border industrial cluster with low-cost-labour and proximity-to-Cambodia-market positioning. The structural-investor read: Aranyaprathet is the structural Thai-Cambodia border node with persistent geopolitical risk overlaying genuine trade-and-labour-flow utility. Watch border-tension diplomatic-resolution cadence, Cambodian-migrant-stock data, and Sa Kaeo SEZ tenant-fill rates as 2026-2028 leading indicators.

Thailand-China Trade Corridor: RCEP and Bilateral-Flow Cycle

China has been Thailand's largest trading partner for the 11th consecutive year per China Briefing. Jan-Apr 2025 saw Thailand record a USD 19.23B trade deficit with China β€” imports USD 31.56B vs exports USD 12.33B β€” per Nation Thailand; April 2025 alone hit a single-month record USD 8.82B in Thai imports from China against USD 3.55B in Thai exports. 2023 full-year bilateral volume reached USD 126.3B with China holding a USD 25.1B surplus. The RCEP (Regional Comprehensive Economic Partnership) effective 1 January 2022 deepens economic ties via phased tariff reductions and unified rules of origin per the Government of China and Trade.gov. Thai exports to China are concentrated in agriculture β€” tropical fruit alone reached USD 5.8B in 2023 (approximately 90% of Thai-China fruit exports). The Trump 2.0 tariff regime drove a 2025 surge in Chinese imports as Thai businesses stockpile machinery and electronics ahead of potential tariff disruption per Mahanakorn Partners and Nation Thailand. The structural-corridor question is whether Thailand can rebalance the bilateral deficit through agricultural-export expansion, FDI absorption (Chinese FDI into Thailand 810 projects / THB 174.6B in 2024 per BOI), and supply-chain-repositioning gains.

Thailand-India Corridor: FTA Framework and Services-Trade Build-Out

Thailand and India operate within a layered FTA framework: the Thai-India Early Harvest Scheme initiated in 2004 covers 82 zero-tariff products including fruits, processed food, gems and jewellery, iron and steel, auto parts, and electronic goods per ADB ARIC. The broader ASEAN-India Trade in Goods Agreement (AITIGA) was signed in 2009 and is now under comprehensive review β€” the 6th Joint Committee meeting was held in New Delhi in April 2025 per Press Information Bureau and India Briefing. The ASEAN-India Comprehensive Economic Cooperation Agreement (CECA) extends beyond goods to cover services and investment, concluded for services and investment at the 10th ASEAN-India Summit in 2012. India's RBI notified a new framework in July 2022 enabling international trade settlement in Indian rupee, with subsequent expansion targeting ASEAN partners as part of broader de-dollarization strategy. Thailand-India tourism corridor: 2.49M Indian arrivals in 2025 with visa-free Thai access since 2024 underpinning structural 20%-plus growth potential per the tourism-recovery report cross-reference. Indian middle-class expansion, Thai cuisine and culture affinity, and low-cost airline connectivity (Thai Airways, IndiGo, SpiceJet, Air India) make India structurally Thailand's most-mature growth-source tourism market.
