If that’s what it takes to stop climate change, why not?
You should probably look more deeply into the structure of Chinese EV subsidies. Recent incentive programs simply involve waiving the purchase taxes for EVs below a certain cost threshold: this increases domestic demand but doesn’t lower costs to the manufacturer. Direct subsidy programs have been progressively phased out and since 2023 no longer exist.
For what it’s worth, subsidies for EV companies are not uncommon. Notoriously, Tesla collected billions in grants, tax breaks, environmental credits, discounted loans, direct incentives, and factory construction assistance and, even today, effectively sits there collecting government income tax rebate money.
