The most important geopolitical concern in Burma/Myanmar right now has to do with the effect that the country can have with regard to the balance of power between the United States and China.
Right now, the US is trying to execute a "pivot" to Asia in its geopolitical strategy. Although it does not say so, the US is primarily concerned that China should not come to dominate the region in an uncontested manner. For this reason, the US is trying to cultivate allies. At the same time, Burma is trying to have some options other than relying on China as its only connection to the outside world. We are likely to see the US and China competing to have influence and connections in Burma.
