In 2023-2024，the Ukraine crisis continues to drag on，enlargement and migration return to the core of European politics. The geopolitical game and the security pressure brought by the conflict between Russia and Ukraine prompt the EU to speed up the process of enlargement. The EU’s approach of using membership as a security-building mechanism may deviate from the accession goals of the candidate countries. The growing migrant/refugee problem is brewing inside and outside Europe. It will test not only the EU’s governance capacity，but also the resilience of European integration. In the relations between Europe and the United States，NATO expanded its membership，and the security situation in Europe deteriorated further. Bilateral security agreements between the United States and many European countries reinforce its military leadership and weaken the practical meaning of the EU’s “strategic autonomy.” The economic and trade relations between Europe and the United States show a trend of two-way expansion of cooperation and competition. In terms of EU-Russia relations，the effect of European sanctions on Russia is limited，and the Ukraine crisis is still difficult to see the dawn of peace. In Africa，migrants and refugees from the region plague European countries. In Asia，Europe has strengthened coordination with the U.S and enhanced multidimensional cooperation with India，aiming to demonstrate its diplomatic positioning as a “global player” through the establishment of the “India-Middle East-Europe Economic Corridor” and the EU-India Technology and Trade Council. The outbreak of the new Israeli-Palestinian conflict has exposed Europe to criticism for its inability to take a unified position on a ceasefire in Gaza. In Latin America，the talks of the EU-Mercosur Free Trade Agreement have been suspended，the EU’s “de-risking” strategy has suffered a temporary setback.
