"The talks were held in a spirit of working together to achieve the UK's orderly withdrawal from the EU," Juncker spokesman Margaritis Schinas told a news conference, adding the bloc was ready to work more on the accompanying declaration of the EU-UK new ties after Brexit, Reuters reported.
Juncker said May presented various options to address her parliament's concerns about the Irish border backstop and that the two agreed their teams would work together on "whether a way through can be found."
Juncker and May would meet again before the end of February, Schinas said. Their Brexit negotiators - EU's Michel Barnier and UK's Stephen Barclay - would meet on Monday.
