Journalist James Surowiecki now seems to have cracked the tariff calculation code.
"They didn't take into account non-tariff barriers at all, as they claim. Instead, they just took the trade deficit and divided it by the country's exports."
Surowiecki gives the example of Indonesia. "We have a trade deficit of $17.9 billion with Indonesia. Exports to us are $28 billion. 17.9 divided by 28 = 64%. And that, according to Trump, is the tariff that Indonesia charges us. What nonsense this is."
In a follow-up tweet, Surowiecki said it was "even worse" than he thought. "Trump's staff only considered the trade deficit in goods. Services apparently don't matter."
And what about Russia?
