In 2015 Ukraine faced many problems：the economy declined precipitously，the government lost its credit，and the renewed conflict in the east became worse. These problems dragged the country into a full-fledged crisis. The main obstacles to resolving the crisis include the following. First，the domestic national identity of Ukrainians remains unresolved，and the imbalance sin socio--economic development are still obvious；Second，the United States and Russia still have a Cold War mentality and confront each other psychologically；Third，the goals of the EU is still unclear：is the EU aiming to achieve high-quality economic development or to expand its political influence at a lower threshold？The external forces of the United States，Russia，and the EU are deadlocked，and their capacity for mediation is limited. The Ukrainian internal split casts a shadow over possible reunification of the country. Ukraine’s new government and the EU haves ignificantly accelerated the integration process，and Russia has suffered isolation，pushing it farther to the East. Future prospects of the Ukraine crisis are uncertain，but the overall situation is not optimistic.
