This is similar to Brazilian banks too. Both public and private.

They stoped using ActiveX in the 00s but then started requiring the user to install some rootkit-like security software that was nearly impossible to uninstall and was probably able to spy on users.

Now they some of them have an app that is basically a bundled browser accessing their regular website.

On the other hand nobody in China uses Web for banking. Most people I know just use mobile applications, which aren't that bad, moreover most of the operations done through AliPay/WeChat/QuickPass, so you don't need to use yacky bank things. Alibaba and Tencent have better UX in their apps. When you go to any bank you feel like a time traveller for 20 years back.

Same for Korean banks
