However, China routinely focuses on certain industries and then uses state incentives to have Chinese companies mass produce products in those industries. It is all but impossible for any company, from any country, to compete with that (without similar government subsidization).

It seems to me that the solution isn't to ban Chinese exports or ignore Chinese subsidies ... it's to allow Chinese products in, with a tariff that balances the subsidization.

(Which is also hard for me to support, as I'm generally anti-tariff ... but it does seem like the right measure here.)
