Issuing Body: Guozun Cathay Associates Thailand Office
Date of Conclusion: 30 December 2025
Core Outcome: Resolved primarily through non-litigation means; full recovery of USD 478,000 principal payment and corresponding late payment interest within just over 3 months
This case was jointly handled by Guozun Cathay Associates Thailand Office and the Beijing Head Office’s Foreign-Related Trade Dispute Resolution Team. In strict compliance with the laws of China and Thailand and the United Nations Convention on Contracts for the International Sale of Goods (CISG), and drawing on Guozun’s global service network covering 106 countries and regions and dual-jurisdiction practice qualifications, we delivered a full-chain, highly efficient debt recovery solution for a Chinese lithium-ion battery exporter.
The case has been selected for Guozun’s 2026 Typical Case Library for Foreign-Related Commercial Dispute Resolution in Southeast Asia. Its case-handling model – “pre-litigation pressure as priority, litigation proceedings as backup, and local asset preservation in support” – has been widely applied to cross-border trade disputes across Southeast Asia.
I. Case Background and Engagement Process
A Chinese high-tech enterprise specialising in lithium-ion batteries had maintained a long-term and stable cooperative relationship with a Thai electronic trading company since 2019. The parties agreed transaction terms via emails, order confirmations, statements of account and other forms, establishing a settlement practice of “shipment first, monthly settlement afterwards”. Between 2019 and 2022, the parties completed dozens of transactions with a sound performance record.
In 2023, affected by overall fluctuations in the Southeast Asian consumer electronics market and the Thai company’s own tight capital chain, payment arrears began to emerge. By December 2023, total outstanding payments had reached USD 623,000. Despite multiple demand letters and in-person visits to Thailand by the Chinese enterprise for collection, the Thai company only paid RMB 1,050,000 (equivalent to approximately USD 145,000) in May 2024. The remaining USD 478,000 was persistently delayed on grounds such as “alleged quality defects in the goods”, “delayed payment from downstream customers” and “operational difficulties”, and the company explicitly refused to sign any written repayment agreement.
After multiple rounds of unsuccessful independent negotiations, the Chinese enterprise was referred to the Thailand Office via Guozun’s Beijing Head Office in September 2025. Given three core complexities – validity of the contract under both Chinese and Thai law, notarisation and authentication of cross-border evidence, and asset tracing and preservation of an overseas company – the Thailand Office activated the China-Thailand Emergency Collaborative Case Handling Mechanism on the same day. A dedicated case team of 6 lawyers was assembled jointly with the Beijing Head Office (comprising 3 locally admitted Thai lawyers and 3 members of the Beijing Lawyers Association Foreign-Related Lawyer Talent Pool), with full authority to conduct debt recovery proceedings.
II. Full Process of China-Thailand Joint Case Handling
The case followed a standardised collaborative model: the Beijing Head Office leads evidence system building and legal strategy coordination under Chinese law; the Thailand Office leads local judicial delivery and targeted enforcement pressure on the debtor. Written records and verifiable deliverables were produced at every stage:
1. 10 September 2025 – 20 September 2025: Dual-Jurisdiction Risk Assessment and Evidence Collation
Beijing Head Office: Conducted a comprehensive review of 6 years of transaction vouchers, over 1,200 email communications, all logistics documents and reconciliation statements. Issued the Assessment Report on the Legitimacy of the Creditor’s Right under Chinese Law, confirming an accurate debt amount and clear breach of contract by the debtor, and completed preliminary preparation of legal documents for both jurisdictions.
Thailand Office: Leveraging the Thai Ministry of Commerce’s enterprise information inquiry system and local asset investigation channels, verified the Thai company’s business registration details, actual operating address, transaction records of 5 corporate bank accounts, list of fixed assets, and goods pending customs clearance valued at over USD 500,000 at Hong Kong port within 7 working days. Ruled out the risk of the debtor having no enforceable assets.
2. 22 September 2025: Simultaneous Service of Formal Bilingual Letter of Demand
Chinese and Thai lawyers jointly drafted a bilingual (Chinese and English) Formal Letter of Demand, expressly citing Articles 11 and 53 of the CISG, Article 469 of the Civil Code of the People’s Republic of China, and Articles 5 and 395 of the Civil and Commercial Code of Thailand. The letter set out the debtor’s payment obligations in detail and clearly outlined all legal consequences of non-compliance, including dual-track litigation in China and Thailand, comprehensive asset preservation, and publication of adverse commercial records. The Thailand Office completed direct service simultaneously to the debtor’s registered address and actual operating address through the Thai courts’ exclusive postal service system.
3. 25 September 2025 – 15 November 2025: Litigation Preparation and First Round of Negotiations
After receiving the Letter of Demand, the Thai company repeatedly proposed unreasonable schemes such as 12 instalment interest-free repayment, but took no practical steps to perform. The joint case team concurrently initiated preparation for court proceedings in Thailand, completing notarisation, authentication and Thai translation of all evidence to make full preparations for formal judicial proceedings.
4. 20 November 2025: Disclosure of Pre-Litigation Asset Preservation Plan
The joint team, together with cooperating Thai counsel, formally disclosed the progress of litigation preparation and the detailed pre-litigation asset preservation plan to the other party. It was clearly stated that if payment was not made within 15 days, an application would immediately be filed with the Thai court to freeze all of the debtor’s bank accounts, seize its fixed assets and detain its goods pending customs clearance at port. Pursuant to Article 234 of the Civil Procedure Code of Thailand, the court may grant an asset preservation order without prior notice to the debtor, and such order shall take effect immediately upon issuance.
5. 15 December 2025 – 28 December 2025: Multiple Rounds of Negotiations and Signing of Settlement Agreement
Under strong legal deterrence, the Thai company voluntarily contacted the joint case team on 15 December to express its willingness to settle. Chinese and Thai lawyers jointly participated in 3 rounds of online negotiations. In response to the other party’s quality defect defence, the team relied on Articles 38 and 39 of the CISG concerning the buyer’s obligation to examine goods and the time limit for raising objections, and effectively demonstrated that the buyer had lost the right to rely on non-conformity of the goods. The parties eventually signed a formal settlement agreement, stipulating that the Thai company would pay the full remaining payment plus late payment interest in a single lump sum within 3 days.
6. 30 December 2025: Full Receipt of Payment and Case Closure
Following the Chinese enterprise’s confirmation of receipt of the USD 478,000 payment and corresponding late payment interest, the joint case team delivered the Case Closure Report and the Risk Prevention Manual for China-Thailand Cross-Border Trade. Four specific risk prevention recommendations were put forward for its future business activities in Southeast Asia.
III. Core Case Handling Difficulties and Authoritative Solutions
The challenges in this case are typical of China-Thailand cross-border trade disputes. Leveraging dual-jurisdiction expertise and extensive practical experience, the Guozun joint team developed a replicable, standardised resolution framework:
1. Establishing Validity of Cross-Border Transaction Without a Formal Written Contract
Legal basis: Articles 11 and 14 of the CISG; Article 469 of the Civil Code of the People’s Republic of China; Articles 5 and 336 of the Civil and Commercial Code of Thailand
Solution: Systematically collated evidence from the full 6-year transaction history to prove that the parties had reached consensus on core terms – including subject matter, quantity, price and settlement method – via emails, order confirmations and statements of account. Combined with the parties’ long-term trading practice, the legality and validity of the contractual relationship were fully demonstrated.
2. Determining Validity of the Buyer’s Late Quality Defect Defence
Legal basis: Articles 38 and 39 of the CISG; Article 474 of the Civil and Commercial Code of Thailand
Solution: Clearly established that the buyer had failed to raise quality objections within a reasonable time after receiving the goods, and that the claim was already beyond the one-year limitation period prescribed by Thai law. The unilaterally alleged quality defects could not constitute a legal ground for refusing to pay the full contract price.
3. Addressing the Pain Points of “Long Cycle and Difficult Enforcement” in Cross-Border Debt Recovery
Legal basis: Agreement between the People’s Republic of China and the Kingdom of Thailand on Judicial Assistance in Civil and Commercial Matters and Arbitration Cooperation; Articles 233 and 234 of the Civil Procedure Code of Thailand
Solution: Adopted a combined strategy of “pre-litigation pressure as priority, litigation proceedings as backup”. Through direct service of legal documents by local Thai lawyers, rapid asset investigation and disclosure of preservation plans, comprehensive legal deterrence was imposed on the debtor, significantly shortening the debt recovery cycle.
IV. Applicable Authoritative Legal Provisions
(I) International Convention
1.Article 11 of the United Nations Convention on Contracts for the International Sale of Goods (CISG): A contract of sale need not be concluded in or evidenced by writing and is not subject to any other requirement as to form. It may be proved by any means, including witnesses.
2.Article 39 of the CISG: The buyer loses the right to rely on a lack of conformity of the goods if he does not give notice to the seller specifying the nature of the lack of conformity within a reasonable time after he has discovered it or ought to have discovered it.
3.Article 53 of the CISG: The buyer must pay the price for the goods and take delivery of them as required by the contract and this Convention.
4.Article 74 of the CISG: Damages for breach of contract by one party consist of a sum equal to the loss, including loss of profit, suffered by the other party as a consequence of the breach.
(II) Chinese Law
1.Article 469 of the Civil Code of the People’s Republic of China: The parties may conclude a contract in written, oral or other form. A data message that can tangibly express the content contained therein and can be accessed for reference at any time, such as electronic data interchange and email, shall be deemed to be a written form.
2.Article 577 of the Civil Code of the People’s Republic of China: Where a party fails to perform its contractual obligations or its performance does not conform to the agreement, it shall bear liabilities for breach of contract such as continued performance, taking remedial measures or compensation for losses.
(III) Thai Law
1.Article 5 of the Civil and Commercial Code of Thailand: A commercial contract may be made in any form, unless otherwise specifically provided by law.
2.Article 395 of the Civil and Commercial Code of Thailand: If the buyer fails to pay the price as agreed, he shall pay interest from the date the price becomes due.
3.Article 233 of the Civil Procedure Code of Thailand: A creditor may, before or during an action, apply to the court for an order of asset preservation if there is evidence that the debtor may transfer assets so as to render the judgment unenforceable.
V. Authoritative Practical Recommendations Based on Case Experience
Drawing on Guozun Thailand Office’s long-standing experience in China-Thailand cross-border legal services, the following four recommendations are offered to China-Thailand trade practitioners:
1.Standardised contract terms: A formal written foreign trade contract should always be executed, clearly specifying the subject matter, quality standards, inspection period, payment terms, breach of contract liabilities, governing law (Chinese law is recommended) and dispute resolution mechanism (arbitration by the China International Economic and Trade Arbitration Commission is recommended).
2.Standardised evidence management: Maintain complete backups of email communications, electronic orders, logistics bills of lading, statements of account, payment vouchers and other materials. It is advisable to conduct notarisation for preservation of electronic evidence every six months to ensure its legal admissibility in both Chinese and Thai courts.
3.Optimised settlement methods: For long-term cooperative clients, a settlement model of “advance payment + balance payment” is recommended, with the advance payment accounting for no less than 30%; for new clients, letter of credit settlement is recommended to reduce transaction risks.
4.Timely enforcement action: Following the emergence of a cross-border payment dispute, instruct a legal team with dual China-Thailand jurisdiction capability within 3 months, to avoid asset dissipation or expiry of limitation periods caused by delay.
