Meanwhile, the trade war has pushed our trading partners to sign trade deal agreements — not with us, but with one another. The list includes Japan and Europe, Europe and the Mercosur zone in South America, and Europe and Mexico. As Chad Bown of the Peterson Institute for International Economics documented, China’s tariffs against the United States rose to 20.7 percent on June 1, 2019 from 8 percent on Jan. 1, 2018 — but its tariffs against all other countries went down from 8 percent to 6.7 percent during that same period.

“Our great Patriot Farmers will be one of the biggest beneficiaries” of the trade war with China, Mr. Trump tweeted in May. Also wrong. Farmers have suffered on all fronts in this trade war. For starters, they saw their production costs rise thanks to the metal tariffs that increased the cost of farm equipment.

Farmers have also been devastated by the retaliation from many countries. For instance, soybean exports to China will most likely — and perhaps permanently — be one-third of what they were last year. Exports of dairy products to China have dropped more than 50 percent, too. Obviously, if farmers did so well under Trump’s trade war, he wouldn’t need to provide them with $28 billion in aid.

Claim 5

During his campaign, Mr. Trump said that he would wipe away the trade deficit. Aside from the fact that this is a foolish goal, his trade disputes have achieved quite the opposite. As my colleague Daniel Griswold documents, “During President Obama’s second term in office, from 2013 through 2016, the monthly trade deficit in goods and services averaged $40.7 billion; under President Trump the monthly deficit has averaged $50.1 billion.”

A reduction in the bilateral trade deficit is a meaningless measure of success because when one deficit goes down, many others go up. Case in point: The deficit with China is going down, but it has been more than offset by rising bilateral deficits elsewhere, including with Vietnam and Mexico. Imports from China are also down 12 percent, but exports to China are down 19 percent. So even by the president’s own mercantilist standard, he is failing.

The bottom line is that pretty much everything Mr. Trump has promised on the trade front by imposing tariffs hasn’t panned out, even if the president persists in saying the opposite.
