ORAc - interesting link about DOKLAM
What I find interesting is that here the Chinese stand by the 1890 Treaty and Bhutan/India stand on historic useage
Elsewhere the Indian side stands on UK/Tibet treaties and the CHinese on historic useage........
This sort of border friction occurs when you have treaties and claims based on 19th Century maps and travellers tales which were incorporated into treaties & claims between much larger countries a long way from the action.
The only peaceful and permanent solution is for BOTH sides to be willing to give and take - and to get some decent maps to work with. The US - Mexico Border is a great example of what can be achieved by quietly adjusting things over a period of years
