The role of the US and China in the post-Covid-19 global economy

The unpredictable change of the SARS-CoV-2 virus in the two years since WHO announced the COVID-19 pandemic has caused the world to suffer heavy losses, including economic instability. economic and social. After more than 2 years of facing the epidemic, the world has learned to live with it, adapt to it, now although global trade at the end of 2021 has had a breakthrough compared to the level before the COVID-19 epidemic- 19 outbreaks, but is facing a deceleration in early 2022. The dominant causes are many, of which an important reason is the "ghost" of the Omicron variant that still looms over the world. According to UNCTAD, the positive trend for international trade in 2021 is mainly due to a sharp increase in commodity prices, while disease prevention and control measures are eased and demand recovers strongly thanks to economic stimulus packages. While these trends are likely to "cool down" and global trade is expected to return to "normality" in 2022, it is still too early to say that the Omicron virus variant will disappear. Meanwhile, the US and China are the two largest and second largest economies in the world, therefore, the uncertainties caused by the pandemic to these two countries also have a heavy impact on the global economy. Therefore, it is extremely necessary to study the role of these two economies in the global economy in the post-COVID period on the basis of analyzing the current situation and proposing some solutions at different levels.
