I give little credit to the US, other than being willing to reach out to Myanmar government, and not bite off our nose to spite our face. But I believe Myanmar wants to be able to enjoy the benefits of their very lucrative relationship with China, without undue worry of becoming the first Chinese province to reach the Indian Ocean and reduce the critical vulnerability of having all ports East of the Malacca Straights.

Shared interests and balancing of power. This is what nations need to do. I believe the Obama administration more willing to be pragmatic than the Bush Administration was; but also that Myanmar government is probably more nervous about the the growth of Chinese influence in their country as well.
