This was the first meeting of the two leaders, held at Venezuela's request, which lasted for about 10 minutes. The encounter followed the historic meeting of Obama with Cuban President Raul Castro.
"We told each other the truth, I would even say it was cordial," Maduro said in an interview with the TeleSUR TV channel Saturday.
He added that, following the summit, the dialogue between the United States and Venezuela would continue.
In March, Obama signed an Executive Order stating that Venezuela threatens US national security. It imposed sanctions against several Venezuelan citizens.
The Executive Order became one of the burning issues of the summit. On Saturday, while giving an official speech, Maduro demanded Obama to withdraw the order, emphasizing that he brought with him 11 million signatures collected worldwide to oppose the order.
The 7th Summit of the Americas gathered the leaders of 33 countries of the western hemisphere and delegations from 35 states.
