Malaysia has duitnow which they recently started making it international. You can buy a coffee in Thailand with a duitnow wallet (ie: BigPay). It is also integrated with AliPay, so you can pay wherever AliPay is accepted (most of China).

I honestly think, at this point, they should just drop the bomb; take their currency to the blockchain (stablecoin) and make the wallets fully connectable to the crypto ecosystem. China doesn't seem keen to take a more open role to capital markets, so there is a void there.
