As with all mass movements where it's a combination of factors l. But the biggest is zero COVID ... You notice no matter how much popularity modi has he could not have sustained lockdown for longer than he did .. he shoved the responsibility to state govts .I have observed this type of disturbance in the past when there was tension/collision with USA during Trump's Trade Wars. It was quickly followed COVID 19 breakout in China.
Something is not adding up. There has been back to back statements from Pentagon, Def Sec and CJCS Gen Milley on Taiwan.
I don't think the US or Taiwan or any other external force is a factor in this.
