These targets are significant achievements of the United Nations in promoting the topic “Migration and Development” and strengthening the human rights-based global migration governance.However, there are many difficulties in achieving these targets, especially when the rights of regular and irregular migration are undermining national sovereignty and security, or are not in line with national development needs. With the continued spread of the CoVID-19pandemic, rising tensions among major powers, and the prevalence of populism and anti-foreigner sentiment in the West, the process of migration and development has been seriously influenced, and the divergent positions and conflicting interests of countries have pushed the migration targets further out of reach. However, in the long run,exploration in this area will help promote global economic recovery in the post-pandemic era and benefit all parties from the positive interactions of migration, development, and human rights.展开更多
