I roughly know about real Chinese designs in Laddakh, what I am not sure about those 10 feet Chinese you were talking about few pages back who wanted water and fishes from Ladakh. Or Chinese who want to connect to central Asia via Laddakh or those Chinese who want to live in Ladakh.If you are so sure that they won't then remove your military simple.
The Chinese I know want to secure their route to Tibet via Xinjiang and keep a route to Chusul to ensure that they have India by juglar vein.
BTW, the military there is to push our claim on the land they have acquired. Remember, we claim lands till johnson line.
