In early 20th century, Britain decided to hand over Aksai Chin to the Chinese administration as a buffer against a Russian invasion. This whole dispute were caused by The Johnson Line and The McMahon Line which were arbitrarily drew by Birtish colonists. The borders of those two area were never demarcated in history expect those two arbitrary lines. So yes, my beef is with the British for who they think they are to decide the things that should be done by two sovereign nations. Not only China and India, most conflicts in the world, Pakistan and India, Israel and the whole middle east are all Britain's handy works.
