HKex investigating some China companies

This article says 3 "private" companies are being investigated and goes on to mention Chaoda, Realgold, China Forestry and Boshiwa,  but doesn't definitively name which companies are being investigated. There is no mention at all on HKex's web site.

It's a start but three companies is a drop in the ocean of fraud on the HKex (where's First Natural?) and it remains to be seen what real penalties can be imposed by the HKex on the mainland based directors who just thumb their noses at the HKex across the border and disappear with the loot.
