Singapore is also a dictatorship, but from a purely economic perspective it is much more open and transparent than China. Companies from the USA and Australia have fairly unfettered access to both the Hong Kong and Singaporean markets.

China is a different story. In May 2015 I was on the expressway to Nanning airport on route to catch a flight to Hong Kong with a friend of mine from Adelaide. My mate said, "have you ever noticed there are no big Australian banks or other businesses operating in Guangxi province and other parts of China" ??

Qantas flies to Shanghai and Beijing, Jetstar from Gold Coast ( Coloongatta ) to Wuhan, but that's it. There are also no large Australian banks in China like ANZ or Westpac. However, in Australia the Bank of China, Construction Bank, Communications Bank are allowed to operate freely. This state of affairs in wrong.
