Heisser Hafen Hongkong and Weiße Fracht für Hongkong.
One of the earlier scenes shows an American spy (as we find out later) walking through the Botanical Gardens in Central to meet his girlfriend, only to discover she has been shot dead. The scene starts on the famous steps before moving to another part of the park with what looks to be the Catholic Cathedral in the background.
Sadly the detail isn't clear because of the nature of this print and it's perhaps too obscure a film for anyone to make any effort in a restoration. Never mind. Is that the Catholic Cathedral spire at the back left? I haven't been to the gardens for a while but I think the front part of it is quite dense with tree growth so I am not sure you get anything like this open view anymore (tall buildings aside).
