Nope. Not even close. This is cope & propaganda taking a word with obvious negative connotations and applying it to a situation where it doesn’t apply to make US consumers, who might otherwise be very happy to see Chinese affordable cars on the US market, accept the protectionism.
Dumping has never meant “offer low prices” or even “offer prices below cost”. Doing the former is fundamental to how markets are supposed to work, and the latter is typically completely acceptable, so much so that we are all familiar with the term loss leader to describe one version of it.
I think the term you and others are groping for is predatory pricing, not dumping. Very hard to prove, though. But even then it doesn’t apply to Chinese companies seeking to win in a new geo, because predatory pricing comprises these three things:
1. Seller has significant market power (e.g., a near-monopoly)
2. They’re doing it with the intent of driving competitors out
3. It is likely to succeed in reducing competition long-term
So it’s an incumbent strategy, not a new entrant strategy.
