Donald Trump sent out a tweet saying he’d like to have a “free market” with the European Union, before agreeing to work towards zero tariff trade deals with Jean-Claude Juncker.
The tweet came before the US President and the European Commission President agreed to work towards "zero tariffs" and "zero subsidies" on non-car goods.
They also said they would work to resolve US tariffs on steel and aluminium imports that have agitated European markets.
Trump had previously criticised Theresa May’s new White Paper Brexit proposal for suggesting the UK would still have a free market with the EU after Brexit, although he did retract his comments in a press conference with the British Prime Minister.
The US president, in a statement with Mr Juncker given in the White House's Rose Garden, said the EU had agreed to buy "a lot of soybeans" and increase its imports of liquefied natural gas from the US.
Mr Juncker, meanwhile, said the US and EU had agreed to hold off on further tariffs as part of trade talks aimed at averting a crippling trade dispute involving the lucrative car market.
Mr Trump told reporters it was a "very big day for free and fair trade" and vowed to "resolve the steel and aluminium tariff issues".
He added: "We will resolve retaliatory tariffs. We have some tariffs that are retaliatory and that will get resolved as part of what we're doing.
"We're starting the negotiation right now, but we know very much where it's going."
Mr Juncker said he had an "intention to make a deal today and we made a deal today".
He said: "We have identified a number of areas on which to work together, work towards zero tariffs on industrial goods. That was my main intention, for those to come down to zero tariffs on industrial goods."
As US soybean farmers have struggled against retaliatory tariffs, Mr Juncker said the EU "can import more soybeans from the US and it will be done".
He said the two sides had also agreed to work together to reform the World Trade Organisation, which Mr Trump has vehemently criticised as being unfair to the US.
