Story from AFR 25 Feb

Fund manager Geoff Wilson sold out of vitamin maker Blackmores and dairy group a2 Milk this week, fearing Chinese authorities would tighten informal import channels, which are a popular way of bringing consumer goods into the country.
Mr Wilson, who runs the listed Wilson Asset Management, which has $1 billion in assets, said both companies are heavily reliant on the so-called "grey" or "suitcase channel" for sales into China and were therefore vulnerable to any crackdown.
This channel usually involves the mailing of goods to China from offshore agents, often avoiding duties and is perceived by consumers to lower the risk of counterfeit products.
"We are still a believer in the Chinese consumer story, but we are worried about the regulator," said Mr Wilson via phone from Sydney.
"There is just too big of a risk that the regulator will crack down, so we have sold out of Blackmores and a2 [Milk], our Chinese consumer stocks."
Late last year the Chinese government announced draft laws to tighten restrictions on imported food being sold to consumers via websites or social media accounts based offshore.
China's e-commerce sector
At present foreign food products sold via China's booming e-commerce sector are largely exempt from local regulations, but the central government appears determined to close this loophole and bring the e-commerce sector into line with traditional retailers.
