I don't think "actively popped" is accurate. I doubt China wanted Evergrande to implode. If I'm reading the news correctly (or having it translated correctly), China's initial policy was to curb over-leveraging and they were hoping that the RE companies would take the hint and start de-leveraging themselves.It is a reasonable assessment because it touched on the generational shift that is going on in China.
This is the furthest thing from burying one's head in the sand.
They've actively popped the RE bubble. They've actively and massively moved investment from RE to a plethora of high value sectors.
The ideal situation would be that everyone would de-leverage themselves successfully and RE companies would massively scale down their ambitions.
