Steven,
I gave phone numbers of the bureau in charge of the investigation of alleged investment fraud by a company with the exact same name as CKGT. I'm not talking to random people on the street. You can ignore me, or you can have a Chinese person call and verify.
I think that studying cases of chinese otc fraud in the past is necessary to avoid it in the future. CDBT is on the pinks now because they stopped reporting. The missed filing coincided with the management of one subsidiary being arrested for investment fraud, the nature of which was similar to the alleged fraud here. The bad news about CDBT was readily available on the internet to anybody who could read chinese for months, but nothing ever appeared in the filings. Investors just woke up one morning and 80% of their money was gone.
I'm just trying to put the pieces together. If the info I found turns out to be meaningless, you have nothing to worry about.
