Replacing the current two bilateral judgment recognition and enforcement(JRE)arrangements， a Multilateral JRE Arrangement among Mainl and China，Hong Kong，and Macao can realize free circulation ofjudgments in China.This Arrangement may also be extended to Taiwan.This article focuses on what lessons China may draw from the US and the EU to develop this Multilateral Arrangement. It first discusses the status quo of the interregional JRE in China.Then itpoints out the four most crucial challenges in developing this arrangement:conflicts between socialist and capitalist law，confl ictsbetweenciviland commonlaw，weak mutual trust，and the lack of a court of final review for cases from all three regions. Importantly，it proposes solutions to each challenge by comparative studies with the US and the EU interregional JRE laws.
