I'm not talking about any tangible result. I just like to see everyone else's reaction to this, cause I for one, think ASEAN did the right thing given what they are.No, nothing will happen even they show up. ASEAN is about as toothless as the UNSC when it comes to security issues.
I feel like most people see ASEAN as an EU like entity, or as a binding organization, where it's actually modelled closer to the UN. I mean, how could they not? How else are you going bring nations of different form of government with varying degree of ideology, with an even greater number of different ethnicities and beliefs under one platform. All decision must be made under a consensus, and like the UN, ASEAN has no say over the sovereignty of each member states.
Now, when it comes to dealing with Myanmar. Everyone seems to think that ASEAN should not engage with the Tatmadaw, and instead have talks with the NUG. Supposed that happen, what power does the NUG holds currently? Aside from popular support, they hold little to no sway over the current situation. On top of that, engaging with with the NUG would undoubtedly drive the Tatmadaw away, leaving them nowhere to go to but China or Russia. If that happen, you can bet that Myanmar will continue on its path on becoming a fail state. Engaging with the Tatmadaw however, means at least having a chance of urging them to change the situation. It might not work entirely given that ASEAN has almost no leverage, and it may not get rid of them entirely, but even if there's even a small chance of stopping the bloodshed, why not take it? Besides, what's stopping ASEAN from talking to the NUG after the summit, thus becoming a sort of peace broker between the two?
Yea, it might pissed off the NUG and the protester, but they need to understand, they are the hostage, and the Tatmadaw is holding a gun to their head. When people urge ASEAN to invite the NUG to the summit instead of the Tatmadaw, it's the equivalent of negotiating for a hostage release by talking to the hostage. Inviting the Tatmadaw had nothing to do with recognizing its legitimacy, even if the Tatmadaw wish to make it seems so (I do believe that's why they even bother coming at all), it's more recognizing the reality of the situation. You had to negotiate with the one holding the gun, regardless of legitimacy.
Of course, most of the protester and activist don't see that. In their eyes, the Tatmadaw is evil and everyone should condemn them, not realizing they can act much worse than now. And if all lines of communication to them is cut-off, then there's no hope of stopping them short of a full-blown war. Sometimes, I think they're too idealistic for their own good, but I kind of understand given that emotions run high, and that they're in the receiving end of the Tatmadaw's brutality.
Call it toothless or whatever, but just like the UN, its purpose is to give platform for communication and prevent an interstate war between ASEAN states, by promoting communication and trade. For that purpose, ASEAN is still useful.
