Is ASEAN back?

It’s hard to know which international forum gets the least done these days, but Southeast Asia’s main ASEAN bloc (Association of Southeast Asian Nations) might traditionally be right up (or down?) there.

To be fair, that’s partly by design, with its consensus-driven and non-interference vibes both somehow necessary to get such a kaleidoscopic group of 11 states turning up, yet also making any meaningful agreement pretty tricky.

This week’s ASEAN summit in Malaysia, however, has made a few more headlines than normal, and it’s worth taking a quick look at the four reasons why, starting with…

1. A new member! 

Timor-Leste finally got a seat at the ASEAN table, and it’s a big deal for all involved:

• Timor-Leste now gets preferential access to ASEAN’s $3.8T economy, a critical step for what is now ASEAN’s smallest (pop 1.4 million), youngest (independence from Indonesia in 2002) and poorest ($1.4k per capita) member.

• And for ASEAN itself, it caps off a 14-year process partly delayed by Timor’s own lack of readiness, but also a quiet lack of bloc consensus: Indonesia was onboard, but others fretted whether a new member would further dilute ASEAN’s cohesion.

Anyway, Timor-Leste passed hazing, making it ASEAN’s first new member since the 1990s, and its first since the bloc introduced formal membership criteria via its 2008 charter.

2. A missing member!

On the flip side, Myanmar’s leader (Hlaing) was again absent, for the simple reason he wasn’t invited. He and his fellow putschist generals have been barred since they signed then shrugged off ASEAN’s ‘Five Point Consensus’ on ending Myanmar’s civil war (basically calling on them to end the violence and start a political dialogue).

And with China and Russia now helping the junta regain turf, the generals have little incentive to re-engage with ASEAN now, particularly as the bloc quietly splinters: some nearer to Myanmar’s chaos (like Thailand) are breaking ranks with their own diplomacy, while others (like Vietnam) are calling for Myanmar’s rival armed groups to be included.

Meanwhile…

3. A new peace?

Donald Trump made an increasingly rare US presidential appearance at ASEAN, mostly to witness the new Thailand-Cambodia peace accord calling for troop withdrawals, prisoner releases, and joint de-mining operations along their contested frontier.

This deal was arguably less about ASEAN, and more a fading glimpse of Pax Americana in the region: the two warring neighbours hit pause after Trump personally intervened, threatening there’d be no US trade talks until their fighting ended. It worked in an immediate sense, but there’s widespread chatter that the underlying irritants will keep festering until the next flareup (Thailand has even been reluctant to call this a peace deal).

There’s one interesting ASEAN angle, however: the bloc will send observers to monitor the truce, which is a big deal for the traditionally hands-off ASEAN.

Anyway, to the extent this ASEAN summit has been more consequential than normal, plenty of credit must also go to…

4. A bold summit host!

Malaysia’s Anwar Ibrahim is not your average leader: he’s been on the scene for decades, knows the key players personally, and has happily thrown Malaysia’s weight around much more since finally taking his country’s top job in 2022.

It was Anwar who started pushing ASEAN harder on Myanmar, and it was even Anwar who brokered July’s initial Thailand-Cambodia ceasefire. Why? Any ego aside, he wants an ASEAN that moves past ‘non-interference’ towards a new mantra of accountability.

And so now, having just hosted possibly ASEAN’s largest-ever summit (with Australia’s Albanese, Brazil’s Lula, Canada’s Carney, South Africa’s Ramaphosa and others there), he hands the bloc’s revitalised reins to its 2026 hosts, the Philippines.
