Potentially, as you have a lot of foreign capital flowing to China right now to take advantage of the higher yields and better stability since China is the only major economy that has COVID19 firmly under control.
However, Chinese capital controls should make it much harder for the bubble to burst suddenly, as foreign funds cannot pull out very quickly, and Chinese market rules automatically suspend trading if there is too much volatility in share prices.
Foreign investment funds and short sellers will hate it, but pension funds and the like who are more interested in stable, long term returns will love it once they get a taste. That is a major reason for US intervention stop stop big American pension funds from investing in China. They are worried that once they get a taste of the Chinese market, that those pensions will never look back to invest the US stock markets again. Even Trump knows the importance of pension funds in helping to stabilise the American stock market and prevent it from becoming a swing machine tailored to short sellers, as would happen if major US pension funds invest elsewhere and investment firms further dominate the market.
I don't think Chinese stock markets allow short selling? They should also put a cap on how much money you can withdraw at once.
