The Convergence of Judicial Rules between Mainland China and Hong Kong has Reached a Higher Level
By Du Tao* and Jingwei Qiu**
With the increasingly close personnel exchanges and deepening economic cooperation between Mainland China and Hong Kong, the number and types of legal disputes between the two regions have also increased. Against the backdrop of adhering to the “One Country, Two Systems” principle and the Basic Law of Hong Kong, the judicial and legal professions of the two regions have worked closely together and finally signed “the Arrangement on Reciprocal Recognition and Enforcement of Judgments in Civil and Commercial Matters by the Courts of the Mainland and of the Hong Kong Special Administrative Region (hereinafter referred to as “REJ Arrangement”) in January 2019, which will come into effect in January 2024. REJ Arrangement aims to establish an institutional arrangement for the courts of the Mainland and the Hong Kong Special Administrative Region to recognize and enforce judgments in civil and commercial cases, achieve the “circulation” of judgments in civil and commercial cases, reduce the burden of repeated litigation, and save judicial resources in the two regions.
Colonialism and German PIL (1) – Colonial Structures in Traditional PIL
This post is the first of a series regarding Colonialism and the general structure of (German) Private International Law, based on a presentation I gave in spring 2023. See the introduction here.
As mentioned in the introduction, this series does not intent to automatically pass judgment on a norm or method influenced by colonialism as inherently negative (I emphasise this because my experience shows that the impression quickly arises). Instead, the aim is to reveal these influences and to initiate a first engagement with and awareness of this topic and to stimulate a discussion and reflection.
The first category, to be discussed today, relates to the (sometimes unconscious) implementation and later continuation of the colonial structure in PIL – now and then.
Colonialism and German Private International Law – Introduction to a Post Series
In March 2023 I gave a talk at the conference of the German Society of International Law. The conference had the title “Colonial Continuities in International Law“ and my presentation focused on “Continuation of colonialism in contemporary international law? – Foundations, structures, methods from the perspective of PIL“. Thus, I was exploring those foundations, basic structures, and fundamental methods of mainly German Private International Law (PIL) and whether and how they have been influenced by colonialism.

UEMATSU on Cross-border Patent Litigation and Lis Alibi Pendens: A Korean–Japanese Case Study for Future Asian Principles of Private International Law

The latest issue of the Ritsumeikan Law Review (No. 43, 2025), a law review in English published by the Ritsumeikan University Law Association since 1986, features a study by Professor Mao UEMATSU (School of Law, Ritsumeikan University) entitled Cross-border Patent Litigation and Lis Alibi Pendens: A Korean–Japanese Case Study for Future Asian Principles of Private International Law.
The article examines a series of patent litigation cases in Korea and Japan, analyzing them to “illustrate the complexity of cross-border patent litigation.” It further argues that, even after reforms to procedural laws in both Korea and Japan, structurally similar cross-border conflicts remain unresolved. The paper concludes with preliminary reflections on possible improvements in legal coordination within Asia.
By introducing case law from both jurisdictions and sharing information on recent legal developments in the region, the study provides valuable material for comparative research and contributes to a better understanding of the dynamics of Asian private international law.
The paper is freely available at the Ritsumeikan Law Review online version here.
