In the era of globalization,commercial transactions readily gain international dimensions and are increasingly delocalized.With a view to establishing effective dispute resolution mechanisms,it is desirable that judgments rendered in one state be recognized and enforced in other states.This is especially important in East Asia,as cross-border business activities are rapidly expanding along with its economic growth.This paper aims to examine the recognition and enforcement of judgments in civil and commercial matters in East Asia with a focus on Sino-Japanese relationships,where the establishment of a reciprocal relationship has posed a considerable challenge.It is worth considering how we can gradually pave the way towards the mutual recognition and enforcement of judgments to achieve coordination among legal systems.
