What would be the consequences if ASEAN expelled Burma from group?

Associated Press reports that an opposition leader in Malaysia urges ASEAN (a group of South east Asian countries who form a geo-political and economical organization - let Burma in as a member in 1997) to expel Burma from the bloc.

I wonder what the consequences would be if ASEAN did do that. Would that mean that Burmese kids would have a harder time studying in Singapore, Malaysia, etc? Would that mean less chances for Burmese workers who want to work in Singapore as manual labourers? I am not sure, so I don't know if I want to support that decision.

"Myanmar's membership in ASEAN must be seriously reviewed as the continued detention of Aung San Suu Kyi marks the abysmal failure of the 10-year ASEAN experiment to influence the Myanmar military junta to be a responsible member of the international community," he (Lim Kit Siang) said in a statement.

But honestly, did ASEAN countries let Burma into ASEAN, just to solely influence them politically? I have a suspicion that that's not the only reason why. What about the economic access that the ASEAN countries have enjoyed in Burma?

Anyway, you can read the whole article from International Herald Tribune, and decide if ASEAN threatening to expel Burma would be a good move to free Daw Suu and the rest of political prisoners. And even if they were no longer confined (remember Daw Suu was free for a few years before being confined to imprisonment at home?), would they be politically practice what they believe in? Would there ever be another election in Burma? 21 questions...
