"I am even more disappointed by their assessment of the Hong Kong situation, and their comment on the weak institutions and governance," said Lam, speaking in an interview with CNBC while visiting the annual World Economic Forum meeting in Davos.

"Because after seven months of social unrest, what has proven to be resilient is Hong Kong institutions, and also Hong Kong governance."
