Hong Kong Stock Exchange Chief Executive Charles Li Xiaojia hopes there could be more financial market connections between Hong Kong and the mainland based on the model of Shanghai-Hong Kong Stock Connect trading link.

Speaking after confirming he has extended his contract at HKEx for three more years, Li said similar arrangements could be made for the derivatives, commodity, fixed - income, international equity and currency markets between the two.

"We have shown this model can work. It is like we opened a Walmart between the two of us: Now we have a shelf for mainland investors to buy Hong Kong shares, and a shelf called Shanghai for international investors to buy," he told an analyst meeting in Hong Kong.
