Sure there are ongoing problems with any banking systen as there are with other specific business areas as well as tax collection and Government supplied services ; hence the need for Parliaments/Government to tweak, amend , repeal or enact new legislation....otherwise if were to be "Set & Forget", that would dramatically reduce the need for parliament or some argue the need for it at all!
IMO since the Chinese Government already owns nearly 50% of businesses (SOEs), the nationalisation of failing businesses such as real estate and related banking is not that big an issue.
For example the US threw $billions of taxpayers money at its failing businesses and its banking businesses during the GFC and facilitated some to take over others while in the Republic of Ireland the Builders/building assets were nationalised and rolled into NAMA (the Bad Bank) as were some of its major banks & Building Societies.
Governments in the USA & Republic of Ireland didn't collapse, nor did their respective Capitalist/ Free Market System(in other words, they didn't throw out the Baby with the Bathwater) so why should we expect that the Chinese Socialist System with Chinese Characteristics to collapse when arguably its current mix of SOEs and Private Enterprise can without major structural change accommodate the nationalisation of failing private enetrprise businesses and besides China's Marxist Philosophy (That Capitalism contains within it the seeds of its own destruction) accommodates that
