If you're talking about tariffs without talking about subsidies and any other assistance or restrictions then you're talking nonsense. Protection exists in many format including grants, tax breaks, promotion, tariffs, subsidies, quotas, foreign investment restrictions, restrictions of certain technologies, administrative barriers, anti-dumping legislation, exchange rate control or limitations or restrictions, certain patent situations, political campaigns, preferential government spending, and so on. That's just off the top of my head.
Comparing just one of those components, and not all of them, is nonsense.
