President Obama and Venezuelan President Nicolas Maduro met privately Saturday amid a bitter dispute between the two nations over recent U.S. sanctions on seven senior Venezuelan officials.

The meeting between the two leaders took place on the sidelines of the Summit of Americas and lasted only a couple of minutes, according a White House official.

The encounter comes after the White House declared the economic and political crisis in Venezuela a national security threat for the U.S. and froze the U.S. assets of seven officials accused of human rights abuses tied to anti-government protests last year in Venezuela.

Maduro and much of Latin American condemned the action as an aggressive throwback to Cold War era that will only escalate tensions further in Venezuela at a time of deep divisions and calls by the opposition for Maduro to resign.

"President Obama indicated our strong support for a peaceful dialogue between the parties within Venezuela," said Bernadette Meehan, a spokeswoman for the White House's National Security Council. "He reiterated that our interest is not in threatening Venezuela, but in supporting democracy, stability and prosperity in Venezuela and the region."

Maduro described the brief moment as frank and cordial. He said the exchange could lead the way to meaningful dialogue between the two nations sooner than later.

"I told him we're not an enemy of the United States," Maduro said. "We told each other the truth."

Obama did not mention the encounter in remarks at the conclusion of the summit.

But during a speech at the summit, Obama defended his administration's right to criticize policies it doesn't agree with.

"When we speak out on something like human rights, it's not because we think we are perfect but it's because we think the ideal of not jailing people if they disagree with you is the right idea," he told regional leaders, without mentioning Venezuela by name.
