The United States leads the world as the strongest economy, with a GDP exceeding $27 trillion. Its success is due to its technological innovation, robust financial market, and ability to attract global investment. China ranks second, with a GDP close to $20 trillion, standing out for its investment in infrastructure and digitalization.
What is missing from this picture is how the Chinese economy has grown exponentially over the last couple decades to reach that second position. It is looking almost inevitable now that it will overtake the US economy in the next couple decades, although Xi Jinping has stifled a lot of the more open aspects of the economy that allowed it to hit this level. When you look at population numbers - 1+ billion versus 350+ billion, it is surprising that the disparity has existed so long. Now there are so many parts of China that look much more impressive than America - the CCP has it's positives and negatives. It is an authoritarian dictatorship that handles disaster badly, but it has been able to direct some impressive infrastructure projects due to centralized power structures.
