China is preparing to set up national security agencies in Hong Kong to deal with pro-democracy agitators. This a day after Beijing introduced a controversial national security law to firm up control over the former British colony. Currently, a Chinese Military garrison comprising over 10,000 troops -- mainly a symbolic presence for external defence -- is stationed in Hong Kong. The public order is maintained by the Hong Kong Special Administrative Region government. The bill is a political bombshell for the former British colony as China has decided to bypass the local legislative council.
