Migration Trends in East Asia and the Pacific: Economic Shifts and Workforce Movements

Migration in East Asia and the Pacific is reshaping economies, driven by labor shortages in aging nations and job-seeking migrants from lower-income countries. Effective policies, skill partnerships, and labor protections are essential to maximize benefits while addressing irregular migration and social challenges.

The East Asia and Pacific (EAP) region is experiencing a significant transformation in migration patterns, driven by economic imbalances, demographic shifts, and evolving policy frameworks. Research institutions such as the World Bank, the International Labour Organization (ILO), and the Organisation for Economic Co-operation and Development (OECD) have extensively analyzed these trends. Migration has grown dramatically, with immigrants more than doubling to 27.3 million and emigrants nearly tripling to 40.8 million between 1990 and 2020. Unlike other parts of the world, migration in EAP is largely intraregional, with over 68% of immigration occurring between neighboring nations. High-income countries like Japan, South Korea, and Australia are major destinations, while lower-income nations such as Myanmar, Indonesia, and the Philippines serve as key sources of migrant labor. Most migration is temporary and low-skilled, though high-skilled migration is also rising, particularly among women and older workers. Countries such as China, Vietnam, and the Philippines are major contributors of skilled professionals to the United States, Canada, and Australia, whereas low-skilled workers tend to move within the region, particularly to Thailand, Malaysia, and Hong Kong SAR, China.

The Growing Demand for Migrant Labor

The rapid aging of high-income nations has fueled labor shortages, compelling these countries to ease visa restrictions, expand work quotas, and introduce pathways to permanent residency. Japan and South Korea, facing severe workforce gaps, are actively recruiting foreign workers. However, irregular migration remains a persistent challenge, particularly in Thailand and Malaysia, where many low-skilled workers enter informally due to high legal migration costs and bureaucratic complexity. This leaves them vulnerable to exploitation, lower wages, and weak labor protections. South Korea's Employment Permit System (EPS) is widely cited as a successful model in reducing irregular migration through transparent recruitment, improved labor protections, and fee-free job matching services.

Migration in EAP is primarily driven by economic opportunity, as workers seek higher wages and stable employment abroad. Limited formal job prospects, high youth unemployment, and widespread informal labor markets push people from lower-income countries to seek work elsewhere. Wage disparities between origin and destination countries are a key factor. For instance, elementary job workers from Myanmar can earn twice as much in Thailand, while Filipino nurses and doctors can make 12.8 times more in the United States. Vietnamese skilled professionals earn up to 16.5 times more abroad than they do in their home country. Yet, high migration costs remain a major barrier, particularly for low-income workers. Recruitment fees alone can amount to several months of wages, discouraging the poorest from migrating. In response, the Philippines has eliminated recruitment fees for workers heading to Saudi Arabia, and South Korea's EPS system has significantly lowered migration costs.

Migrant Labor: A Pillar of National Economies

Labor demand in destination countries shapes migration trends. High-income nations actively recruit foreign workers to fill shortages in sectors like healthcare, construction, and technology. Australia and New Zealand have expanded labor migration schemes for seasonal and semi-skilled workers, while Japan and South Korea have eased visa restrictions to attract caregivers, IT specialists, and engineers. Singapore and Malaysia rely heavily on foreign labor in construction and services, as local workers prefer higher-skilled jobs.

The COVID-19 pandemic further underscored the critical role of migrants in keeping key industries running. In Australia, strict travel restrictions on international students and working holiday visa holders led to severe labor shortages, particularly in agriculture and hospitality. When restrictions eased, demand for migrant workers surged, demonstrating their importance in sustaining economic growth.

For origin countries, migration provides an economic boost through remittances, which support household consumption and long-term investments. In Cambodia, remittances increased total consumption by 12-14% and helped reduce poverty by up to 6 percentage points. However, migration also poses social challenges, particularly for families left behind. Children of migrant workers often experience emotional distress and educational setbacks due to parental absence, highlighting the need for stronger support systems for migrant households.

Skill Drain vs. Skill Gain: The Human Capital Dilemma

Migration has complex effects on human capital. While high-skilled migration can lead to brain drain, it also stimulates educational investment and skill development in origin countries. The Philippines provides a clear example: When the United States adjusted its visa policies for nurses, nursing enrollments in the Philippines surged, generating a 10-fold increase in graduates.

Return migration further contributes to skill enhancement. South Korea, Taiwan, China, and Vietnam have benefited from returnees who bring back global expertise. In Taiwan, China, returning professionals have played a pivotal role in the semiconductor and technology industries, while in Vietnam, returnees helped expand the tech sector. Circular migration patterns have also supported knowledge transfer and innovation in various sectors.

However, high-skilled emigration can create labor shortages in key sectors like healthcare and engineering, especially in small economies such as Pacific Island Countries (PICs). The loss of skilled professionals is particularly problematic in specialized fields, as seen in Fiji and Papua New Guinea, where many healthcare professionals migrate to higher-paying jobs abroad, leaving behind gaps in essential services.

Policies to Maximize Migration Benefits

Governments across EAP are reforming migration policies to maximize economic gains while addressing labor market concerns and social tensions. Destination countries are increasingly aligning migration policies with labor demand, improving integration services, and mitigating competition between migrant and native workers by investing in upskilling programs.

Origin countries are focusing on enhancing skills development, improving transparency in labor migration, and implementing stronger reintegration programs for returnees. Countries such as Vietnam, Cambodia, and Indonesia are expanding vocational training to help workers secure higher-paying jobs abroad. The Philippines has one of the world's most comprehensive migrant support systems, offering business loans, job search assistance, and training programs for returning workers.

Bilateral and regional cooperation is strengthening migration governance. Skill partnerships between origin and destination countries ensure that migrant workers acquire industry-relevant qualifications, making them better suited for labor market needs. Improved data collection on migration patterns and recruitment costs is another critical step toward reducing exploitation and irregular migration.

Migration is a defining force in the EAP region, shaping economic, social, and political landscapes. While it offers tremendous opportunities for economic growth, it also presents challenges that require carefully crafted policies. Expanding regular migration pathways, reducing recruitment costs, and strengthening protections for migrant workers will be crucial in ensuring sustainable migration governance in the decades ahead.
