Elon has mentioned Weibo IIRC, but I think Alipay is a closer analogy for short-term intentions. Elon's financial services intentions have not changed in concept since 2010, although both technology and regulations have changed.
We've often discussed these plans here, including the Tesla and SpaceX (e.g Starlink) implications. He repeatedly refers to X.com intentions, thwarted when Thiel sold him out when he was on holidays. The video of Elon's aspirations is within the post fo his McLaren delivery I posted here a few days ago.
Within 12-18 months Tesla will certainly benefit from the payment innovations. Think deposits, loan/lease payments, merchandise and, don't forget, subscriptions and Superchargers.
The Chinese analogues in Weibo and AliPay were described succinctly back in 2014:
Sina Weibo, the microblogging platform often called China's Twitter, has partnered up with Alipay to launch a new payment platform called Weibo Payment. Users of Sina Weibo's iOS app can now access Weibo Payment, which is an important part of the strategic partnership between Sina and Alibaba...

I don't know when the Tesla announcements will be made; my speculation is that once the regulatory, processing and systems issues have been sorted there will be announcements.
In the meantime until the bots issue has been squashed and Twitter rejuvenation has been well undertaken these things will not happen.
Personally I've been waiting for this since 1999. Oddly nobody has really done this in the US, even though much of it has been done elsewhere. Almost all of us are underestimating the potential.
Just one example: Nubank (look it up) was founded in 2013 with a narrowed vision drawn from the same idea. From nothing it has become the most valuable bank in South America.
There are several examples around the world.
Elon was in 1999 the only one who actually had the grasp of the totality. This Twitter deal is only to facilitate the future, while providing notoriety for a massive amount of political machinations that have only peripheral consequences for the vision. That in no way ignores how consequential all those machinations can become.
We are living in interesting times.
