More often than not, these chinese r/m in the otc don't turn out to be anything big. A lot of them turn out to be scams, over hyped, or share selling schemes. Plus things take longer as communication is always a barrier and Finra takes closer look at these which takes longer for them to process...
Just take a look at the most recent ones. (cglo, cdno, sbes, cnct, hdii and a whole lot more.)
