I'm not super smart when it comes to this stuff, but I think China has a lot more tools in fighting a trade war.
- They can very easily manipulate the value of their currency
- They are not a democracy, and can thus do whatever they want
- They can subsidize their industries
- They can and do ship products through 3rd countries to take advantage of lower tariffs through them
- Their consumers have far higher tolerance for discomfort than the average American
- Their consumer class is increasingly able to purchase their own goods
- China has already stated no rare earth minerals to the US
- There are a lot of products that have no domestic alternative. They're almost exclusively made in China, perhaps a few alternatives world wide, but not enough to fill the US market demand - those products will cause the average American a lot of discomfort
I'm not opposed to negotiating reduced tariffs, or imposing tariffs with a clear strategy. But it appears as though there is no strategy here. Or maybe the strategy is to be unpredictable and scare China that way. Maybe we realized that engaging in a trade war with the whole world at once only motivates other countries to form alliances against us.
In my opinion, blanket tariffs are dumb. Tariffs are used to level the playing field, or to protect your national industries. If we want to export widgets to China, and they make their own widgets, and put a tariff on our widgets, then we find something they export to the US, an state "we're going to tariff this, unless you take the tariffs off our widgets."
So the question is, what do we export to China that they put tariffs on? What new markets will open or grow if they drop tariffs on all American goods? Conversely, if we drop all tariffs on Chinese goods, how will that affect our local industries?
All that being said, we have the largest economy in the world, and the most consumeristic and wasteful society in the world. Everyone wants to sell us stuff, and we want to buy from everyone. That does give us a good bit of bargaining power.
