Re: And Why is Britain Not Enforcing the Two-China Agreement.
How, sending a "gun boat"?
The actual border between Lower Kowloon and the New Territories is Boundary Street. Short of building a wall (Think Berlin Wall) down it and cutting off over 50% of the people in HK, HM Government realized there was no way HK would work in that situation. There were enough problems with Chinese administered Kowloon City before it was demolished.
BTW, I live 250 metres south of Boundary Street.
