Shifting trends in economic development have significantly altered the nature of migration flows in Asia, rendering them more diverse and more complex. Consequently, migration has become a recurrent theme in regional debates on trade and capital movements. Moreover, migration and labour market trends in Asian countries have implications for non-Asian OECD countries, both in terms of their economic links to the region -- capital investment and trade -- and in terms of possible migration to OECD countries. This publication, based on a workshop series jointly organised by the Government of Japan, the Japan Institute of Labour, the OECD and the International Labour Organisation, analyses recent trends in international migration movements and policies in East and South-east Asia. Individual country reports on Indonesia; China; Hong Kong, China; Japan; the Republic of Korea; Malaysia; the Philippines; Singapore and Thailand, describe in detail foreign worker flows and trends in foreign employment, while also providing an overview of the main characteristics of economic growth and labour market change. Asian countries are seeking to combat illegal migration and manage migration flows in accordance with both labour market requirements and the ability to absorb foreign workers. To what extent can sub-regional economic development play a role in channelling migration flows in a more orderly fashion? What is the nature of emigration in Asia and what are the reasons behind it? These issues are examined in a context of rapid labour force growth for some Asian countries and with an eye to identifying strategies to generate more job opportunities in sending countries.
