Note to Chinese posters: There are a few posters from North East states including Sikkim (I believe Tshering is from Gangtok, Sikkim, Jaunty is Assamese and there are a few others), who are rabidly pro-mainland-India. But if you do a google search on North East Indian states and look at the history of these places since 1947, you will see a different reality. I suspect these are people who are from collaborator families who have benefited from Indian occupation of these places. Naturally they need to defend Indian occupation which is not welcome by majority population of these places.
What is needed is a campaign of radio broadcasts and websites to reach these populations in their native languages, so they can be informed about their options for the future. North East states has only a 14 mile wide connection through Chicken neck with mainland India. On all 3 sides of this triangular space is China, Myanmar and Bangladesh. The only weak spot currently is Myanmar. When and if Myanmar is back under Chinese sphere of influence, and Awami League is ousted from power in Bangladesh, it will become easy to influence events in this region. The keys are to have a long term plan, convince the local population the seriousness of this plan and then let them fight for their self determination, which is their right under UN Charter. It took 800,000 armed security forces to pacify 7 million Kashmiri's, but India will be bankrupt if it has to pacify a majority of 40 million population fighting against Indian occupation.
If the independence of NE states can be achieved then Nepal, Bhutan as well as NE states will get sea access through Bangladesh sea ports. Currently India forces Nepal and Bhutan to use Indian ports and NE states have no sea access, one is however planned and being constructed via Myanmar.
This will not only help recover South Tibet for China, but it will also help liberate 230 million people in Nepal, Bhutan, NE states and Bangladesh who are currently suffering under mainland Indian occupation/domination. who will forever remain grateful and allied to China.
