British Prime Minister Boris Johnson spoke to US President Donald Trump on the phone ahead of their one-on-one talks on Sunday on the sidelines of the G7 Summit in France.

A statement from the prime minister’s office said that they “looked forward to speaking further” at the G7 summit in France.

It will be their first meeting since Johnson became British prime minister.

The G7 summit comes nearly two months ahead of the Brexit deadline on Oct. 31.

Trump has consistently praised Johnson and predicted a speedy US-UK trade deal after Brexit.

Johnson will meet European Council President Donald Tusk in their first face-to-face meeting.

The G7 Summit follows a hectic week of diplomacy for Johnson, who visited Paris and Berlin in an effort to persuade the EU to amend the withdrawal agreement it reached with his predecessor Theresa May, the BBC reported.

Johnson pledged that his country would leave the European Union (EU) by the deadline no matter whether the government reaches a new Brexit deal with Brussels.

Earlier on Wednesday, Johnson welcomed a potential “blistering timetable of 30 days” to find an agreement with the EU on the terms of Brexit.

He was responding to a suggestion by German chancellor Angela Merkel that a short timeframe for negotiations on a Brexit deal was possible.

During a press briefing in Berlin, Merkel said a solution could be found in establishing “absolute clarity” on the EU-UK future relationship.

The Summit, which also comprises Canada, France, Germany, Italy, Japan and the US, runs from Saturday to Monday.

Issues on the agenda include the global economy, tackling inequality and responding to the challenges of the digital age and the rise of Artificial Intelligence.
