Recent years have witnessed the rise of populism, defeat of multilateral trade agreement, and crisis of the Covid-19 pandemic that has resulted in globalization backlash. The trend of de-globalization was already on the rise everywhere and poses various compelling challenges to the existing international migration regime that rooted in the wave of globalization. However, at the same time, the scale of international migration in East Asia increases in line with diverse factors, such as changing geopolitics, vibrant transnational economy, and ongoing climate change. Against this backdrop, it is intriguing to analyze in what ways and to what extent the wave of deglobalization has (re)shaped the governance model and strategy of transnational migration regime in East Asia. Using the approach of comparative constitutional studies, this research project aims at analyzing the abovementioned questions on the migration governance of refugees, asylum seekers, stateless persons, migrant workers, and their family members and immigrants (such as marriage immigration or skilled immigration) in Japan, South Korea, Taiwan, the Philippines, and Indonesia. After analyzing the results from these studies, this research project further aims at providing a nuanced understanding of constitutional governance of transnational migration in East Asia under the context of de-globalization and sheds light on the studies of international immigration with Asian narratives.
