Myanmar has been exploring an appropriate path of political transformation since its independence in early 1948，but has repeatedly failed to establish a political system suitable to its national conditions. Upon independence，Myanmar implemented parliamentary democracy，but to no avail. Then it established a military rule which lasted as long as half a century. In 2010，Myanmar embarked on its transition process from military to democratic politics，and over the past several years，significant progress has been made. More benign and intensive interactions with the international community，including the US-represented West and the ASEAN，have become an important external motivation for Myanmar’s transformation. Objectively speaking，the current round of restructuring in Myanmar is facing both the constraints from the complex domestic issues and the impact of the intensifying competition of word powers in Myanmar. The sucess or failure of the transformation depends largely on Myanmar’s capacity to promote positive interactions between the internal and external motivations.
