I think the somewhat negative CCTV coverage is having an effect in China.
what happened? The Chinese dear leaders sold a bunch?
No, if they wanted to sell they'd tell the masses to buy.
If they are warning the masses away it's because the leaders want to buy before the prices goes higher.
This is just wishful thinking. The only thing the leaders care about is stability and maintaining power. They absolutely do not want to see anything that could threaten this.
