The United States will continue to talk with the European Union (EU) on the Transatlantic Trade Investment Partnership (TTIP) agreement, despite Britain's vote to leave the EU.

The agreement to get a TTIP has now been affected in light of the decision by the British people over the weekend, said Eric Schultz, White House principal deputy press secretary at a briefing on Monday.

"If we have to start negotiating separately with the United Kingdom, that's going to start from a different vantage point," Schultz said.

Also on Monday, US Trade Representative Michael Froman said that a lot of progress has been made on the agreement during the last eight month.

"The economic and strategic rationale for TTIP remains strong," he said at the Bretton Woods Committee annual meeting.

"Our goal remains to continue working with the EU to conclude an ambitious, comprehensive and high standard agreement this year."

Froman also admitted the US government was evaluating the effect of Brexit on the TTIP negotiations.
