I put a wrong word though
Not nominal ally, but a close friend though
Myanmar and Indonesia have close political relationship, Myanmar support us a lot during our war of independen, not only funds but medicine, foods, arms and political support. Our first National carrier, Garuda Indonesia first operated in Myanmar served Calcutta Rangoon flight. Myanmar further support our National integrity by supporting our move and concept of Archipelagic doctrine in United Nation during U Nu tenure as UN general secretary. Then they supporting our claims over West Papua during Trikora operation against Dutch. Further Indonesia and Myanmar is original founder of Non alignment movements during cold war. Indonesia is always supported and backing Myanmar to joint ASEAN, a move to made Myanmar not only close and rely to China as usual and open them to western power and other countries . Indonesia is full supporting Myanmar move toward democracy and give lot of advice and support during political transtition from Junta. And Indonesia never once condemn Myanmar action in Rakhine, but instead trying to help the people there by building Hospital and school there. And so on
