Responsibilities Before 1 July 1997, the British government had the political commitment to safeguard the territory against external and internal threats. Commonwealth forces were also deployed to station in the territory shortly before the Second World War. The greatest test was in 1941, when Japanese forces invaded Hong Kong, leading to the 44-month-long Japanese occupation of Hong Kong. Internal Security was the responsibility of the Hong Kong Government, in particular the Royal Hong Kong Police. It was supported by British Forces in Hong Kong should it be called upon to do so.
