Some key features of the draft national security law for Hong Kong, which China released Saturday:
1) The draft law aims to tackle separatism, subversion, terrorism and collusion with foreign forces, BUT it remains unclear what activities would constitute such crimes and what the punishments would be.
2) Power of interpretation rests with the Chinese parliament, which means Beijing will have the final say over how the law should be interpreted.
3) Provisions in the security law would supersede existing Hong Kong legislation should the two conflict.
