Issuing Body: Guozun Cathay Associates Singapore Office
Date of Conclusion: 26 January 2026
Key Outcomes: Led the entire arbitration proceedings at the Singapore International Arbitration Centre (SIAC), fully recovered the disputed funds, successfully removed the client from the global high-risk merchant list with zero damage to business reputation, and shortened the case cycle by 40% compared with the industry average.
This case was jointly handled by the Singapore Office of Guozun Cathay Associates and the cross-border commercial dispute resolution team of the Beijing Headquarters. In strict compliance with Singapore law, the SIAC Arbitration Rules and the regulatory requirements of the Monetary Authority of Singapore (MAS), and leveraging Guozun’s Southeast Asia cross-border legal service network and dual-jurisdiction practice qualifications, we delivered a full-chain, high-efficiency cross-border dispute resolution solution for Chinese overseas enterprises.
This case has been included in Guozun’s 2026 Library of Typical Cross-Border Commercial Dispute Resolution Cases. Its case-handling model – dual-jurisdiction evidence authentication + local arbitration procedure leadership + regulatory compliance pressure – has been widely applied in resolving cross-border payment disputes across Southeast Asia.
I. Case Background and Engagement Process
The client is a leading technology enterprise based in China. Its Singapore branch, serving as the regional operating entity for Southeast Asia, signed an exclusive payment service agreement with a top-3 global online payment service provider to process online transaction collections and disbursements across 6 jurisdictions including Singapore, Malaysia and Indonesia, with an average daily transaction volume exceeding US$200,000.
In May 2025, without fulfilling its prior notification obligation or providing any evidence of non-compliance, the service provider unilaterally froze all funds in the client’s Singapore branch accounts and added the branch to its global high-risk merchant list. This caused the suspension of all the client’s online transactions in Southeast Asia, delayed salary payments for nearly 300 local employees, and resulted in direct economic losses of over RMB 1 million. The client communicated with the service provider’s Asia-Pacific headquarters 11 times via email and video conference, but all requests for account unfreezing and list removal were rejected on the grounds of “internal risk control rules”.
On 3 June 2025, the client was referred to the Singapore Office through Guozun’s Beijing Headquarters. Given the three core challenges of the case – leadership of Singapore arbitration proceedings, validity recognition of cross-border electronic evidence, and payment industry regulatory compliance – the Singapore Office activated the China-Singapore Emergency Collaborative Case Handling Mechanism on the same day and established a dedicated case team together with the Beijing Headquarters. The team comprises 2 locally practising Singapore lawyers (familiar with SIAC arbitration rules and the MAS regulatory framework) and 3 members of the Foreign-Related Lawyer Talent Pool of the Beijing Lawyers Association (proficient in cross-border business of Chinese enterprises and electronic evidence preservation), with full authority to represent the client in arbitration proceedings.
II. Full Process of China-Singapore Joint Case Handling
This case adopted the standardised collaborative model: the Beijing Headquarters is responsible for evidence construction under Chinese law and client coordination; the Singapore Office is responsible for advancing local judicial procedures and liaising with regulatory resources. Written work records and verifiable deliverables were produced at every stage:
1. 3 June 2025 – 7 June 2025: Dual-Jurisdiction Case Risk Assessment
Beijing Headquarters: Sorted out the equity structure of the domestic parent company and the Singapore branch, as well as cross-border fund flow records; issued the Compliance Assessment Report on Cross-Border Payment Business under Chinese Law; confirmed the lawfulness of the client’s transaction activities; and identified potential compliance risk points.
Singapore Office: Verified the validity of the payment service agreement under Singapore law; reviewed 12 MAS regulatory penalty cases from the past 3 years concerning payment service providers’ abuse of risk control powers; and assessed the likelihood of success in arbitration. Meanwhile, it verified the respondent’s assets in Singapore via the Accounting and Corporate Regulatory Authority (ACRA) and local banking channels in preparation for enforcement.
2. 8 June 2025 – 15 July 2025: Electronic Evidence Preservation and Dual-Jurisdiction Authentication
Beijing Headquarters: In strict accordance with the Several Provisions of the Supreme People’s Court on Evidence in Civil Proceedings, conducted hash value verification and blockchain timestamping on all electronic data dating back to 2023, including transaction records, communication history with the service provider, and risk control freeze notices. An electronic evidence notarial certificate was issued by the Beijing Chang’an Notary Public Office to confirm the integrity and non-tamperability of the evidence.
Singapore Office: Pursuant to Article 7 of the Electronic Transactions Act of Singapore, arranged for authentication by the Singapore Academy of Law and confirmation of local validity for the notarial certificate issued by the Chinese notary office. At the same time, it submitted an information disclosure application to MAS to obtain records of complaints against the respondent for similar risk control measures in the same period, strengthening the evidence chain of the respondent’s abuse of risk control discretion.
3. 16 July 2025 – 20 August 2025: Arbitration Filing and Procedure Advancement
Singapore Office: Drafted the arbitration application in compliance with the SIAC Arbitration Rules (2023 Edition), setting out four clear claims: full refund of the disputed funds, removal from the global high-risk merchant list, compensation for interest on detained funds, and payment of all arbitration costs by the respondent. It represented the client in submitting the filing application and complete evidentiary materials to SIAC, and followed up on arbitral tribunal formation, service of documents and other procedural matters throughout to ensure the case proceeded swiftly to the merits stage.
Beijing Headquarters: Assisted in preparing notarised and authenticated documents for the client’s legal personality certificate and power of attorney; kept both the Chinese parent company and the Singapore branch updated on case progress; and coordinated with business departments to supplement relevant transaction background information.
4. 25 September 2025 – 19 January 2026: Written Submissions and Multiple Rounds of Negotiations
Beijing Headquarters: In response to the respondent’s statement of defence and counter-evidence, produced 3 supplementary legal opinions from the perspectives of contract interpretation, breach of contract constitution and application of the good faith principle. It refuted the respondent’s core defence that “risk control measures are contractually agreed” point by point, and clearly established that the standard clauses purporting to exempt the service provider from its primary obligations are invalid.
Singapore Office: Attended 2 procedural meetings convened by the arbitral tribunal, and made oral submissions on the admissibility of electronic evidence under Singapore law and the limits of payment service providers’ risk control powers. It also organised 3 online and 2 in-person negotiation sessions, disclosing to the respondent the potential MAS regulatory penalties for its violations, and creating a dual-track pressure dynamic of “arbitration proceedings + regulatory complaint”.
5. 20 January 2026 – 26 January 2026: Settlement and Case Closure
Lawyers from both China and Singapore jointly drafted the bilingual (Chinese-English) settlement agreement, which expressly provides that the respondent shall, within 3 working days of signing: fully refund the disputed funds; immediately remove the client from the global high-risk merchant list; issue a clarification letter to its affiliated global credit reference agencies; and bear all arbitration fees and legal costs of the case.
Singapore Office: Oversaw full performance of the settlement agreement. After confirming that the full disputed amount had been received and the client had been removed from the global high-risk merchant list, it represented the client in submitting a closure application to SIAC.
Beijing Headquarters: Delivered the complete set of case files to the client, issued the Special Report on Risk Prevention and Control for Cross-Border Payment Business in Southeast Asia, and provided targeted recommendations for the client’s future operations.
III. Core Case Challenges and Authoritative Solutions
This case is a representative dispute in Southeast Asia’s cross-border payment sector, and the challenges involved are common issues faced by Chinese overseas enterprises. Drawing on dual-jurisdiction expertise and local resource advantages, the Guozun joint team developed a replicable, standardised solution:
1. Defining the Boundaries of Payment Service Providers’ Unilateral Risk Control Powers
Professional Basis: Article 45 of the Payment Services Act of Singapore, Article 14 of the Contract Act of Singapore, and the Code of Conduct for Payment Service Providers issued by MAS
Solution: Systematically reviewed the Risk Control Guidelines for Payment Service Providers issued by MAS and relevant precedents of the Supreme Court of Singapore, clarified the judicial principle that “risk control powers must not be abused”, and proved that the respondent had failed to fulfil its obligations of prior notification and giving the merchant a right of defence. Its internal risk control rules cannot override mandatory legal provisions and contractual agreements.
2. Enforceability of Removal from the Global High-Risk Merchant List
Professional Basis: Article 37 of the SIAC Arbitration Rules (2023 Edition), Article 58 of the Contract Act of Singapore
Solution: Specified the exact timing, scope and verification method for list removal in the settlement agreement, with an agreed liquidated damages of 0.5% of the disputed amount per day for delayed performance. The respondent was also required to issue an official clarification letter to global card schemes such as Visa and Mastercard, as well as major credit reference agencies, to fully eliminate any impact on the client’s business reputation.
3. Admissibility of Cross-Border Electronic Evidence in Arbitration
Professional Basis: Article 22 of the SIAC Arbitration Rules (2023 Edition), Article 7 of the Electronic Transactions Act of Singapore, and the UNCITRAL Model Law on Electronic Commerce
Solution: Adopted a dual-authentication model of “Chinese notarisation + Singapore local authentication” to preserve the full lifecycle of electronic evidence – generation, storage and transmission. An application was also made to the arbitral tribunal to appoint an electronic evidence expert to issue an expert opinion, ensuring the evidence was fully admitted by the tribunal.
4. Facilitating Efficient Settlement in Arbitration Proceedings
Professional Basis: Article 14 of the International Arbitration Act of Singapore, Article 37 of the SIAC Arbitration Rules (2023 Edition)
Solution: Proactively put forward phased settlement proposals at key procedural milestones, and simultaneously initiated a complaint procedure with MAS. Regulatory pressure brought the respondent back to the negotiating table, significantly shortening the case resolution cycle.
IV. Applicable Authoritative Legal Bases

2.Article 12 of the Code of Conduct for Payment Service Providers (issued by MAS): A payment service provider shall not place a merchant on a high-risk list without justifiable cause. It shall promptly correct erroneous risk control determinations and take necessary steps to mitigate adverse consequences.
V. Authoritative Practical Recommendations Based on Case Experience
Drawing on Guozun Singapore Office’s years of experience in cross-border payment legal services in Southeast Asia, the following three authoritative recommendations are offered to Chinese overseas enterprises engaged in cross-border payment business:
1.Standardise Payment Service Agreements: When entering into agreements with overseas payment service providers, clearly define the specific criteria for “high-risk transactions”, the procedures and time limits for implementing risk control measures, and the dispute resolution mechanism (arbitration at the Singapore International Arbitration Centre is recommended). Remove any standard clause that unilaterally exempts the service provider from liability or imposes disproportionate obligations on the merchant.
2.Implement Routine Electronic Evidence Preservation: Regularly back up and notarise electronic data including payment transaction records, communication history with service providers, risk control notices and billing vouchers. It is recommended to conduct blockchain timestamping every six months to ensure the evidentiary value of electronic data in cross-border disputes.
3.Adopt Pre-emptive Dispute Resolution and Risk Early Warning: Establish an early warning mechanism for cross-border payment risk control. When a service provider raises abnormal risk control requirements, engage professional lawyers immediately. In the event of account freezing or inclusion in a high-risk list, initiate arbitration proceedings within one month to avoid irreversible operational losses caused by prolonged fund detention.
