"...-if that is the case is that fear based on something tangible such as past experiences here or just a basic fear of not being able to trust some Chinese businesses."
Just "some" is right, as in Chinese RTOs (reverse mergers), which SIAF is. After the debacle in the last 3 years with Chinese RTOs, many U.S. investors won't come near them. However, most U.S. listed Chinese non-reverse mergers are doing extremely well.
Whether deserving or not, SIAF has been cast in with the bad apples. My opinion is that SIAF is dead money for a long time unless it makes it to the FN or gets off the U.S. OTC.
