Here's the strategy behind Trump's dangerous trade war with China

If you look at the trade numbers with China, you can discern what President Trump might be thinking as he drags the United States into an escalating trade war.

Trump has upped the ante yet again, beginning the process to slap tariffs on $200 billion worth of Chinese imports, in addition to $34 billion already subject to new tariffs and $16 billion that’s about to be. Since there have been many volleys in this competition so far, let’s first review the Trump trade war scorecard. Here are the tariffs Trump has actually imposed (in green), along with those he seems likely to impose (in yellow) and others he has merely suggested (in orange):

The Trump tariffs on solar panels, washing machines, steel and aluminum apply to imports from many countries, including China. But those apply to just $57 billion of goods.

Trump is targeting China in particular much more aggressively. If we add up the tariffs already imposed with those in the process of being imposed, Trump could hit $250 billion worth of Chinese imports with new tariffs by the fall.

That number matters—to Trump, at least. He has long complained about the U.S. trade deficit with China, which was $336 billion in 2017. Let’s look at a breakdown of the 2017 numbers:

U.S. imports of Chinese goods and services: $524 billion

US exports of goods and services to China: $188 billion

Overall trade deficit with China: $336 billion

At the beginning of his trade war, Trump seemed to think China wouldn’t dare impose retaliatory tariffs on U.S. imports if he did the same to Chinese imports, even though most trade experts predicted that would happen. They were right and Trump was wrong. China has imposed its own tariffs on U.S. imports almost dollar-for-dollar, to match those Trump has imposed. There’s every reason it will continue to do so.

But China only imports $188 billion worth of U.S. goods and services per year. Ah ha! Once both countries have imposed tariffs on $188 billion worth of imports from the other, then China starts to run short of ammunition, according to the Trump playbook. At that point, Trump can keep imposing tariffs on Chinese imports, all the way up to $524 billion worth, while China will run out of imports to tax at a paltry $188 billion.

How China can retaliate

Maybe that explains why Trump has mentioned adding yet another $200 billion in Chinese imports to his tariff list, if his new tax on the first $250 billion worth of Chinese imports doesn’t get the job done. That would push the total of newly tariffed Chinese imports to $450 billion, which is getting close to all of them.
