That article was published in 2009. Now 3+ years later, it's gone down from $7+ to $1.8 last year. The past few months it's been hovering around $2.5. So from 2007 when it IPO's till now, investors have lost over 2/3's their investment.
Like many companies, they over-estimated China's population. The biggest problem with China is their mentality. They are more than happy to get western manufactured goods but then they cant' afford it as there's a 100% tax on imported goods. Even Starbuck's has to sell a lower grade coffee in China just to keep their costs down.
Bottom line....China will not trust China made drugs. Cant' blame them either. May take an entire generation to change this thinking.
