Although the epidemic continued in 2021，European countries gradually lifted border control，and international population flow has almost been back to normal. The number of asylum applications and approvals，as well as the issuance of resident visas，have basically returned to the pre-COVID-19 levels. The number of people illegally entering or staying is on the rise. The stock of refugees and migrants is also increasing. European countries still need to reconcile the dilemma between the principle of humanitarianism and the principle of national interest. In political，economic，social and international cooperation，the EU and its member states face difficulties in managing refugees and migrants. In the external environment，Europe is not only confronted with the Polish-Belarus border disturbance，but also with a new round of refugee flows brought about by the dramatic changes in the global landscape and increasing regional and national conflicts and turbulence. Therefore，in order to stabilize the situation in Europe and promote the process of “Europeanization”，the EU should carry out more effective management and innovation in the reception，settlement，repatriation and integration of migrants and refugees beyond the territorial boundaries of member states and beyond the transit countries and countries of origin of migrants in the future.
