The leaders pledged to expand European imports of USA liquefied natural gas and soybeans and both vowed to lower industrial tariffs, excluding autos.
While Washington and Brussels pursue these aims, the leaders agreed "we hold off further tariffs and reasses existing tariffs on steel and aluminum", Juncker said.
Trump warned at a cabinet meeting last week that he would move forward with 25 percent auto tariffs if the meeting with Juncker didn't go well.
While the White House offered few specifics about the agreement, the joint appearance did represent a break from the cutting rhetoric Trump and some European leaders used this year and, for now, appeared to soften concerns about an all-out trade war between the major economies and allies.
Meanwhile, Mr Trump has accused China of "vicious" tactics, tweeting that China was specifically targeting United States farmers with retaliatory tariffs because "they know I love & respect" them.

EU Trade Commissioner Cecilia Malmstrom, who is accompanying Juncker, said the EU is drawing up a list of $20 billion in United States products to be targeted for retaliation if the trip fails.
The Trump administration has threatened new tariffs, and the president is reportedly considering up to a 25 percent tariff on automobile imports - one that could spark more retaliation and affect already hard-hit communities in vehicle manufacturing hubs like Michigan, Ohio and Kentucky.More news: Tape reveals Trump and lawyer discussing payoff over alleged affair
"We have good arguments, clear numbers and we have ideas, too".
"I don't think our farmers and ranchers long-term want these programs".
"I understand what he's trying to do", Ryan said of the president, "and the goal he's trying to achieve is a good one: a better deal for Americans, better trade agreements".
Commerce Secretary Wilbur Ross, briefing reporters aboard Air Force One, said more jobs have been created by the steel and aluminum tariffs than are being lost and he said the tariffs were instrumental in the European Union talks.
