The ASEAN summit will convene in April 2018 and Singapore is proposing an ASEAN-EU integration in its capacity as chairman.  Currently, China-ASEAN meeting is convened in Vietnam.

Singapore knows that it has lost the trust of China as Philippines is now the de facto ASEAN facilitator.  Therefore, SG is proposing an ASEAN-EU integration to counterbalance Philippines-China leadership in ASEAN.

Let's see how this will pan out.  Hopefully, SG won't be ostracized by other ASEAN members in the end.
