The BBC's chief business correspondent Linda Yueh in her coverage of the Alibaba IPO on 25th September 2013 suggests that the Hong Kong regulators are trying to protect the principle of 'treating all shareholders equally'.

This question is going to be raised once again as the Hong Kong stock exchange now considers the position of minority shareholders who have commenced Section 152FA legal proceedings with Chairman Leung Ngai Man of Sino Prosper State Gold Resources Holdings Limited (HKG:0766). This is relatively new statute imported from Australia and its precedent value will be a key indicator of whether or not regulatory oversight in Hong Kong has failed.
What do others think? Toh Han Shih of the South China Morning Post is also watching this story closely. He carried a very interesting story on 7th August 2013 about Sino Prosper State Gold Resources and proposed connected party transactions with Sino Prosper Chairman Leung Ngai-man.
