Ann: Partnership with Alipay to power instalments on AliExpress, page-76

LOL or get no response.

Global Solution.
Use your own trusted credit card.
Authorise payment release once the goods arrive.
Solves the trust issues of dealing with an unknown counterpart in a foreign country from both the seller and the buyer.
Embedded in the payment systems and can be rolled out to more networks.

Fraud is rife in the online buy/sell world.

PayPal will refund the buyer if they complain but do not ensure that the goods are returned. So it only works for one counter-party and doesn't ensure that the complaint is legit and you pay upfront.
All of these type of sites have a rating for how users behave when dealing with others - for a reason. Fraud.
MC Visa etc do not do this - you pay upfront.
BNPL cannot do this - you pay upfront with a micro loan.
