How much exposure does the Western world have to this? My guess would be "not much". It'll sting some emerging market investors, but I don't think you'll see a massive knock-on here.
China has basically been the single biggest driver of global growth over the past decade. Its highly overleveraged real estate market is a huge threat to its overall economy, and that has plenty of potential to create a massive knock-on.
