We dont need to be recognized by Vietnamese
We need to play our "Muslim card" more, something that has been started already by military cooperation with some major Muslim countries this year. Palestinian struggle is also one of our foreign policy interest where ASEAN is not a place that can help it in any way. Talking about Rohingya in Myanmar, our government are active now there by helping both groups (Muslim and Buddsh).
It is likely that we are going to stay but with more Indonesian interest in it, feeling good because of being acknowledged as a leader by compromising our own interest is our past policy. Last administration foreign policy under Susilo Bambang Yudhoyono is to make zero enemy and many friends. Not any more now.
