At this point I believe its the international market that is subsidising Chinese EVs. Take a look at the byd dolphin mini / seagull. It is priced starting at $21,000 in mexico while the price in China is from $9700. You find many other examples of the same car models sold at much higher price overseas than locally in China.
The opposite of dumping is happening. For example the Kia EV5 is sold at [$20k in China](https://electrek.co/2023/11/17/kia-launches-20k-ev5-electric-suv-china-rival-tesla-model-y/) while the same made in China model is sold overseas [Starting at $46k](https://electrek.co/2024/04/04/kia-set-to-export-this-all-electric-suv-at-a-price-that-undercuts-tesla/)
