I couldn't take a photo of the border any closer than this. The nearest building with the double roof is the Nepalese customs house. To the right of it you can see the "Friendship Bridge" and the Chinese customs and immigration buildings.
Looking at this area today on Google earth it seems that fairly sizable towns have been built on both sides of the border. In 1972 the area was almost empty. Now of course there is also a heavy traffic of goods and tourists going this way. Times have changed in 42 years.
It's a terrible photo, i know, but I show it just for fun. All kids in Benin who wanted to be photographed always stroke this kind of pose of Asian martial arts masters. I noted in my diary that "culture imperialism" didn't always come from the West.
