Current migration and displacement. One in three migrants comes from Asia and the highest ratio of outward migrants is seen from hazard-exposed Pacific countries . In 2019, approximately 1900 disasters triggered 24.9 million new displacements across 140 countries; in particular, Bangladesh, China, India and the Philippines each recorded more than 4 million disaster displacements . Tajikistan, Kyrgyzstan and Russia see significant disaster-associated displacements: for example, heavy rain-induced flooding in Khatlon  triggered 5400 new displacements; landslides in the Jalal-Abad  saw 4700 new displacements; and floods in Altai, Tuva and Khakassia  displaced 1500 people. Iran reported the highest sub-regional figures with >520,000 new disaster-related displacements in 2019 . In Southeast and East Asia, cyclones, floods and typhoons triggered internal displacement of 9.6 million people in 2019, almost 30% of total global displacements . With most migrants in the region being temporary migrant workers, loss of jobs and wages among them have been particularly severe due to adverse economic climate triggered by COVID-19 . It has also resulted in large-scale returns of migrant workers, and remittances have declined drastically . Remittances to Eastern Europe and Central Asia are expected to decline 16.1% from 57 billion USD in 2019 to 48 billion USD in 2020. Remittances in East Asia and the Pacific are estimated to fall 10.5% over the same period, from 147 billion to 131 billion USD . The COVID-19 pandemic has had significant impacts on migrants  in the region, and some countries have targeted migrants in economic stimulus packages or income-support programmes; however, access to such support has been heterogeneous.
