Perhaps most surprising was Trump's complete reversal regarding China, which he once accused of "raping" the United States and made the villain of much of his tough talk on trade during the campaign.
For those suffering from policy whiplash, here is a quick guide to where Trump now stands.
Trump told the paper he'd changed his mind because China hasn't been manipulating its currency for months.
Throughout the campaign, and as recently as 10 days before this announcement, Trump falsely blamed China for being a "world champion" of devaluing the yuan. He failed to do so but still continued to accuse Beijing of interfering in the foreign exchange markets.
In an interview with the Wall Street Journal, he said he would not label China a currency manipulator, despite having repeatedly pledged to do so on his first day in office.
Six months ago, candidate Trump suggested he was eager for an alliance with Russian President Vladimir Putin.

"We are now seeing, for the first time in many, many years, an increase in the number of troops in Europe", said Stoltenberg. "After listening for 10 minutes, I realized it's not so easy. They're leaving the profession", Trump told me in July 2015.
"I said it was obsolete", Mr. Trump said. "It's obsolete because it wasn't taking care of terror".
After talks with Nato Secretary General Jens Stoltenberg, the US President reiterated his call for member states to meet the alliance's two per cent of GDP defence spending target, but said he no longer considered the alliance obsolete.
During the campaign, Trump repeatedly said North Atlantic Treaty Organisation countries were not shouldering their fair share of defense costs, leaving too much of the burden on the United States.
Stoltenberg, however, expressed gratitude to Trump directly Wednesday for his emphasis on boosting allied defense spending. I think it's a lot of excess baggage.
He also indicated he might consider reappointing her next year, saying she would not be "toast".
There is no sign, for instance, that Trump is pulling back from other controversial positions - including doubling down on border enforcement and expulsions of undocumented immigrants. Number one, I think the distribution of costs has to be changed. On Wednesday, he confirmed it.More news: Ramos and Pique rivalry underlines Clasico tension
When you're running for president, or when you're watching politics on a sidelines as a reality TV star or businessman, it's easy to lob baseless rhetoric. "I'd be against it".
He said at a November 2015 primary debate: "I got to know him very well because we were both on 60 Minutes, we were stablemates, and we did very well that night".
Currently, just the United States and a handful of other countries are meeting the 2% target.
"So instinctively you would say it's a ridiculous thing but actually it's a very good thing and it actually makes money".
"I like to think of myself as a very flexible person".
Tillerson said the US and Russian Federation also agree that North Korea must be "de-nuclearized" and that there needs to be more communication between senior staffers from the former Cold War powers "both at a diplomatic and military level".More news: Rays' Odorizzi injured, makes early exit vs. Red Sox
