Thailand is a major commercial hub in Southeast Asia.
Foreign investors regularly enter cross-border contracts involving Thai counterparties in manufacturing, logistics, agriculture, infrastructure, maritime transport, and digital trade.
When disputes arise, the core issue is rarely the commercial intention.
It is usually contract architecture.
Below are seven strategic drafting mistakes that frequently trigger international trade disputes in Thailand.
1. Failing to Expressly Choose Governing Law
Thailand has not ratified the CISG.
If a contract is silent on governing law and litigation occurs in Thailand:
• Thai conflict-of-law rules apply
• Thai substantive law may ultimately govern
• International trade expectations may not be reflected
Contract certainty begins with a clear governing law clause.

2. Misunderstanding Thailand’s CISG Position
As of 2026:
• Over 90 countries are CISG members
• Singapore and Vietnam are CISG members
• Thailand is not
The CISG does not automatically apply in Thai courts.
It may only apply if:
• The parties expressly choose it; or
• Conflict-of-law rules lead to the law of a CISG member state
Assuming CISG coverage without express drafting creates unnecessary risk.
3. Weak or Ambiguous Jurisdiction Clauses
International contracts frequently contain generic jurisdiction language such as:
“Disputes shall be resolved in Thailand.”
This is insufficient.
In Thailand, international trade disputes may fall under the jurisdiction of the Central Intellectual Property and International Trade Court.
Without precision:
• Jurisdiction challenges may arise
• Parallel proceedings may occur
• Enforcement complexity increases
Jurisdiction drafting must align with asset location and enforcement strategy.
4. Incorrect Use of INCOTERMS and Trade Instruments
In practice, disputes often arise from misunderstanding:
• INCOTERMS allocation of risk
• Transfer of title timing
• Documentary credit conditions (UCP)
• Shipping documentation inconsistencies
Thai courts may consider international trade customs under Section 4 of the Civil and Commercial Code.
However, international instruments do not override Thai law unless properly incorporated.
Documentation precision matters more than commercial expectation.
5. Choosing Litigation Without Considering Asset Location
Thai court litigation may be efficient domestically.
However:
• Thailand has limited reciprocal enforcement treaties
• Foreign court judgments are not automatically enforceable in Thailand
• Thai judgments may face enforcement obstacles abroad
Where counterparties hold assets outside Thailand, arbitration may offer stronger cross-border enforceability under the New York Convention.

6. Silence on Dispute Resolution Mechanism
Contracts that omit a structured dispute resolution clause often default into:
• Thai court jurisdiction
• Procedural uncertainty
• Delayed enforcement strategy
Strategic contracts should address:
• Governing law
• Seat of arbitration (if any)
• Institutional rules
• Language
• Interim relief powers
Dispute resolution planning must occur at drafting stage — not after escalation.
7. Confusing Public Trade Regulation with Private Commercial Enforcement
International trade disputes between businesses are private contractual matters.
They are distinct from:
• WTO state-to-state disputes
• Anti-dumping regulatory proceedings
• Public trade compliance actions
Foreign investors sometimes misinterpret international frameworks as automatically influencing private enforcement.
In reality, contract drafting determines outcome far more than multilateral trade policy.
Litigation vs Arbitration in Trade Disputes
International trade disputes in Thailand may proceed through:
• Court litigation
• Domestic arbitration
• International arbitration
Litigation may offer:
• Established procedural system
• Specialised trade court
• Cost predictability
Arbitration may offer:
• Neutral forum
• Confidentiality
• Stronger international enforceability
The correct choice depends on asset structure and counterparty profile — not preference.
Strategic Conclusion
International trade disputes in Thailand rarely arise from substantive legal ambiguity.
They arise from:
• Incomplete governing law clauses
• Weak jurisdiction drafting
• Misunderstood trade instruments
• Misaligned enforcement planning
Cross-border dispute strategy is fundamentally a contract design issue.
For foreign investors, risk mitigation must begin before signature.
At Ake & Associates, our approach to international trade matters prioritizes structured drafting and enforcement planning — with litigation and arbitration positioned as protective mechanisms, not reactive measures.
