That being said I doubt they will get rid of them because that isn't really the way China works. For taxis, you really need an ICE at the moment. For delivery vehicle not so much. Every delivery vehicle that I've seen in cities is electric. The trucks between cities aren't but lots of the intercity deliveries are by train (some is electric some isn't).
One thing to be aware of is that China generally has tough laws that are not well enforced. This is by design. They don't have to change the law they just need to enforce it more strictly.
What generally happens is that the laws are introduced into the top tier cities and then slowly out to other cities over time. What they have been doing is increasing the emission requirements. This is to bring down pollution. We had an old jeep that we rented that had to be tested every 6 months because of its age. There was a loophole that let us pass the test. It cost a little bit more but we could drive it. The government knew about the loophole and let it exist for a few years then closed it. You knew it was coming just not when. I think the jeep was moved into the country or sold for scrap.
The emission requirements will just keep slowly going up. There will be way around the requirements (which they are aware of) but they will slowly make it harder and harder. If you really want an ICE it will still be possible but when you go for a new car it will just be less effort and easier to get electric.
This is why I have an electric moped. I could get a petrol one which would technically be illegal but it is just so much easier to get electric.
