Cazalet - I was thinking of the LAND border that caused the '62 War following Tartares post........
There the argument wasn't helped by poor maps - in the SCS no-one argues about the geographic locations - just how far you can push the boundary.......
The Chinese always used to be quite reasonable and adjusted the land boundary with most of their neighbours - but in the last 20 years they have started the "China as a Great Power" line and are pushing their sea boundaries wider and wider. As it takes two to agree any boundary it's causing a lot of this trouble.......
