> China can outlast the US on this one.
So let's get the story so far. The US put tariffs on China. People complain about this because it's "hurting US importers" and "costing more to American consumers" etc. But it also puts the hurt on China because now their goods are less competitive, and paying 5% more than China to buy manufactured goods from Latin America or some other part of Asia hurts the US a little but hurts China a lot.
So China responds by devaluing their currency. Now their prices are competitive again, even with the tariffs, but the result is that now the thing you used to buy from China for $100 that was momentarily $110 (so that you bought it from Mexico for $105) is now back to $100. That gets people buying from China again, and paying the original prices, only now of the $100 China used to get, they only get $90 and the US treasury gets $10.
Meanwhile this allows the US to raise the tariffs even more for the same cost to the American consumer. Or just leave them where they are forever and enjoy the 10% China has effectively volunteered to discount its goods by.
> Next up, let's crash the price of oil and flip off the Iran sanctions
Then OPEC cuts production because they're a cartel and all they need is to keep oil competitive with renewables, not have it cost significantly less than that. But it may come down some and then Trump gets voter support from lower gas prices. And the lower oil prices allow oil to better compete with the batteries and solar panels that are manufactured in China, causing China to lose business. And China is on the "climate change is especially bad for this country" list, so that's not great for them either. Meanwhile it gives more cover for Trump to escalate the trade war in retaliation for violating the Iran sanctions. Not really the biggest win for China.
