I have often worked for the chinese market, and in the past I had to hire a developer to package Cordova plugins with AliPay and WeChatPay SDKs. Chinese developer, since most of documentation is in chinese.
I have lately stumbled on this company, which offers ANEs with AliPay and WeChatPay SDKs!!!
They also made an App Uploader for the Apple Store which works on Windows and Linux.
Damn! I wish I knew that when I did last chinese app…
Seams like AIR crossed the great china wall
