India and Burma
Upper Burma was annexed after the Anglo-Burmese War in 1885 CE. England had complete dominion over Burma by 1897 CE.
Britain was the colonial power
Because at that time great britain was a colonial power that saw burma and the far east in general as connected to its main colony, India. In view of David Cameron's visit to Burma and the west in general's 'sucking up' to the military junta my best guess is a share in the abundant natural resources of that gentle country.
In 1989, the military government changed the name from Burma to Myanmar. This change has not been universally recognized at this time. England for example still refers to this country as Burma in its newspapers.
Burma
Burma has a junta government. That is a form of oligarchy.

Myanmar, Burma
"We are Burma"
Burma. Myanmar was originally known as Burma, and that is still its official name. No legislature in Burma has actually approved the name Myanmar, which is derived from the Burmese short-form name Myanma Naingngandaw and has been promoted by the military authorities in Burma.The conventional long form of the country is Union of Burma, and this in the local long form is Pyidaungzu Myanma Naingngandaw.
Burma is governed by their military.
