Cross-Border Judgment Enforcement: China, Hong Kong, and Singapore Rulings in Korean Courts

For years, the realistic answer on court judgments between Korea and China was “probably not,” and practitioners steered clients to arbitration by default. That has changed. Korean and Chinese courts now recognize each other’s judgments, and China has taken a broader view of reciprocity. Hong Kong and Singapore enforce Korean money judgments at common law, and Korea’s reciprocity test is flexible enough to reach their judgments too. Arbitral awards still move among all four jurisdictions on the firmer footing of the New York Convention.

The Korean Side: What Every Foreign Judgment Has to Satisfy

Article 217 in Brief
A foreign judgment needs four things to be enforced in Korea: international jurisdiction, proper service, consistency with public policy, and reciprocity. Enforcement then goes through an execution judgment lawsuit.

Why Reciprocity Is the Pivot for Asian Judgments
Since 2004, the other jurisdiction’s recognition requirements need only be substantially equivalent to Korea’s. No treaty and no prior precedent is needed. In June 2025, the Supreme Court recognized a Malaysian judgment on this basis. Reciprocity is assessed legal system by legal system, so Hong Kong is analyzed separately from mainland China.

Korea and China: From Uncertainty to Established Reciprocity

Korean Courts Recognizing Chinese Judgments
In 1999, the Seoul District Court recognized a judgment from a Shandong Province intermediate court. In July 2019, the Daegu High Court recognized a Beijing district court judgment, relying on:

• the 1999 precedent;
• the 2016 judicial cooperation memorandum between the two supreme courts;
• the lack of any substantial difference between the two countries’ recognition rules.

Chinese Courts Recognizing Korean Judgments
In 2019, a Qingdao court recognized a Korean money judgment for the first time. Recognitions followed in Shanghai and Beijing, including the first Korean IP judgment. In December 2024, the Beijing Fourth Intermediate People’s Court enforced two Korean trademark judgments. It based that on “de jure” reciprocity: Chinese judgments can be recognized under Korean law, so no matching precedent was needed.

China’s Broader Shift on Reciprocity
Since 2022, Chinese courts no longer require proof that the other country has actually recognized a Chinese judgment. They also accept reciprocity based on the other country’s law, a mutual understanding, or a reciprocal commitment. China’s Civil Procedure Law was amended in 2024 to set out the review grounds in more detail.

What Can Still Go Wrong
Chinese courts have dismissed Korean enforcement applications on jurisdictional grounds. Service and procedural fairness are still reviewed closely in both directions.

Hong Kong: Common Law Enforcement Without a Treaty

Korean Judgments in Hong Kong
Korea isn’t covered by Hong Kong’s statutory registration scheme. A Korean creditor instead sues on the judgment as a debt under common law. The judgment must be final and conclusive, for a fixed sum, and from a court with jurisdiction. Defenses are limited to fraud, public policy, and natural justice. In 2022, the Hong Kong Court of First Instance enforced a Korean judgment on exactly this basis.

Hong Kong Judgments in Korea
Hong Kong enforces foreign money judgments without requiring reciprocity, so Hong Kong judgments should pass Korea’s substantial-equivalence test. There is little direct Korean precedent, so prepare the reciprocity argument rather than assume it.

Singapore: A Similar Common Law Picture

Korean Judgments in Singapore
Korea isn’t a gazetted country under Singapore’s registration act and isn’t party to the Hague Choice of Court Convention. A creditor brings a common law action instead. The judgment must be final and conclusive, for a fixed sum, and from a court with jurisdiction. Reciprocity isn’t required.

Singapore Judgments in Korea
For the same reason as Hong Kong, Singapore judgments should generally meet Korea’s reciprocity requirement, subject to a specific analysis.

How This Compares to Arbitral Awards

One Treaty Covers All Four
Korea, mainland China, Hong Kong, and Singapore all apply the New York Convention. KCAB, CIETAC, HKIAC, SIAC, and ICC awards can be enforced across all four without any reciprocity analysis.

China’s Internal Safeguard for Foreign Awards
A Chinese lower court that intends to refuse a foreign award must first report the case up the court hierarchy, ultimately to the Supreme People’s Court. That makes refusal harder in practice.

Side-by-Side

Where Court Judgments Can Still Make Sense
Litigation still makes sense when the assets are in the same place as the court, when local interim relief is central, or when a court clause already exists. Non-money judgments can be enforced in China, as the 2024 trademark decision shows, but generally not through the common law actions in Hong Kong and Singapore.

Practical Sequencing for Korea–China–Hong Kong–Singapore Disputes

1. Identify where the counterparty’s reachable assets are before choosing a forum.
2. Default to arbitration for new contracts that touch several of these jurisdictions.
3. If a court clause already exists, check the specific enforcement path.
4. Serve through proper judicial assistance channels, with translations.
5. Seek a money judgment if Hong Kong or Singapore enforcement may be needed.
6. Secure assets early in the country where you’ll enforce.
