No, because they're hardly enforced. China has been blatantly dumping a buttload of products for decades and the U.S. has been asleep at the wheel as it continues to hollow out our domestic manufacturing industries even further.
America can't do that because the government takes bribes from banks and believes in Friedmanite ideology where state investment is evil. It's a great opportunity for Europe to copy China and become independent.
By that account China would be bankrupt by now because subsidizing a "buttload" for "decades" does cost a lot of money.
I think the reality is much more subtle - they force their way into a new market if needed and then stop and let the market forces do their thing.
