I think it won't happen anytime soon. Although I'm not closing the possibilities.
China has been far ahead in terms of combatting the pandemic crisis. I applaud their pacing in addressing the needs of their citizens despite having a breakout early last year in one of their cities. China's economy has slowly recovered compared to the neighboring countries that are still stuck from lockdowns and quarantine protocols. Which I think have a nice impact to their economy because the residents can freely move and the businesses are fully operational.
However, let's also put into consideration that the vaccines are on roll already. Soon enough, majority of the countries will achieve herd immuty through the help of vaccinations. This will help most countries recover, particularly the US. Let's not forget that US is still the leading country in the world despite the pandemic crisis. So, I think, China will still have a hard time competing to get the top spot and replace US as having the largest global economy by 2028.
But then again, who knows? Only time can tell.
