There is always uncertainty in the future, but there is no doubt that the uncertainty of the world is higher than that of China. For 2020 alone, if the US were to be viewed, it would first face one of the most socially torn general elections since World War II, with the world economy as a whole weak and trade war still in the shadows, and what impact the stock market will have on the U.S. economy after even innovation, not an easy topic. In addition, the korean peninsula is facing major new challenges, the greater middle east, a number of hot spots in the united states, can be said to have a number of \"gray rhinoceros\" looming on the horizon of america's domestic and foreign affairs.
From a European perspective, Brexit has gone from short-term to long-term pain, while Europe's bigger problem is the loss of momentum in the economy and the growing social tensions that have focused on the Middle East refugee problem and the polarization of the rich and poor. The EU's ability to solve problems is weakening, and Europe's relations with the US are getting colder, with confusion still running through Europe's 2020, or even the entire 1920s.
From the point of view of Japan and the Republic of Korea, their ability to lead their own development strategy in the 2020s and 1920s is stronger than that of the general countries, but their ability to do so is inadequate given the high risk of the global strategic situation. How will the United States use Japan and South Korea? How will the two countries handle the complex relationship between China and the United States? South Korea is also heavily constrained by the nuclear issue on the peninsula. Both countries seem to need stability, and it is hard to become a world-class bright spot in the 1920s.
