Obama warns against 'adversarial' Brexit negotiations

"No one has an interest in protracted, adversarial negotiations," Obama said after meeting European Council head Donald Tusk and European Commission chief Jean-Claude Juncker at a NATO summit dominated by Britain's post-EU future.

The two-day NATO summit gathering 28 member state leaders in Warsaw was initially meant to focus on Russia after the Ukraine crisis but Britain's shock vote to quit the EU was on everyone's mind as the potential political, security and economic repercussions become clearer.

Obama said that despite the problems posed by Brexit, European integration was crucial and the United States had a major interest in its continued success.

"Even as we face the difficulties of this moment we cannot lose sight of the extraordinary achievement that European integration continues to be," he said, praising the bloc's shared values of democracy and peace.

"For all the reasons I just mentioned, the United States has a strong and enduring interest in a united Europe."

British Prime Minister David Cameron, who is to meet Obama during the summit, stepped down last month after losing the Brexit referendum but he said starting negotiations with Brussels would be left to his successor, expected to be named in September.

Tusk, Juncker and many EU member states have pressed Britain to begin the negotiations immediately but in London the preferred option is to proceed with extreme caution, leading some to say Britain may even be stalling on the talks.

Juncker, who has expressed dismay at the delay and pressed hardest for the talks to start as quickly as possible, said they would not be hostile.

"We have to engage in negotiations. And I'm not doing this, how I could say, in a hostile mood," Juncker said.

Tusk said the "political consequences of Brexit may be very serious" and stressed that "maintaining the closest relations is equally important".

"But it is equally important to send today a strong message to the whole world that Brexit ... is just an incident and not the beginning of a (disintegration) process," he said.
