The paper analyzes the underlying reasons of successful fight of Chinese leadership and Chinese people against coronavirus. We have revealed factors contributing to mobilization of Chinese citizens and their commitment to win. The causes and factors that have contributed to the weakening of the United States in the fight against the epidemic are identified. The outbreak is a powerful impetus for China and its leadership, which declared the epidemic a «holy nation-wide war.» The Chinese leadership has learned its lessons and is taking necessary measures to eradicate the weak links and deficiencies identified during the epidemic. China, as a responsible power, will cope with this and further strengthen the state government system and the unity of Chinese society. China promotes a system of joint international prevention and control and supports the effective role of international organizations. Evidence of all this can be seen in financial assistance and warm support that countries provide to China. All this demonstrates the interdependence of all countries and increases the need to create a «community of common destiny». Dr. Trump administration’s policy leads to a deeply dividing nation, and many Americans are frustrated with its domestic and foreign policies. Considering US actions in the fight against coronavirus, the author hopes that the country will collaborate with China and other nations to strengthen cooperation not only in the fight against the virus, but also in other areas. This will bring a great number of benefits not only to these nations, but to the whole world.
