"In my conversation with the president-elect, he expressed a great interest in maintaining our core strategic relationships", said Obama here at his first press conference since last week's presidential election, adding that he would deliver that message to foreign leaders during his final overseas trip starting later Monday.
"The most important point I made is that how you staff, particularly your chief of staff, national security advisor, white house advisor, how you setup a process and system to surface information, generate options, understanding the president is the final decision maker, that has to be tended to right away", Obama said.
"There are going to be certain elements of his temperament that will not serve him well unless he recognizes them and corrects them", Obama said, pointing out the impact that a comment from a USA president that is not accurate can have around the world.
Mr Obama said USA foreign policy remained quite stable despite changes in administration, in part because of the breadth of United States government interactions with other nations.
"Because of the nature of the campaigns, and the bitterness and the ferocity of the campaigns.it's really important to try to send some signals of unity, and to try to reach out to minority groups and women and others that were concerned about the tenor of the campaign", he said.
"We're going to have to compete everywhere", he said, reflecting on his own 2008 win in Iowa, a state that went for Trump this time.
Obama said it would not be appropriate for him to weigh in on all of Trump's appointments because it would be incompatible to his desire to provide a smooth transition of power to his successor. "As long as he's got good people around him and he has a clear sense of direction", the president said. I think he recognised that, I think he's honest in wanting to be a successful president. "I think, ultimately, he is pragmatic".
In his first extended remarks on the election that pounded his party and his legacy, Obama sought to reassure an anxious world and nation about his successor's commitments to alliances, at times appearing nearly sanguine about a future Trump administration.

The Real Madrid superstar scored a penalty and missed another as well as notching a thunderous volley at the Estadio Algarve. With the clock ticking down, William Carvalho restored their lead before Ronaldo made up for his penalty miss to make it 3-1.
"The people have spoken", he added.
Mr Trump's comments echoed longstanding USA complaints that too many North Atlantic Treaty Organisation allies do not live up to their pledge to spend 2 per cent of gross domestic product on defence. He added that it is important for Trump to reach out about those needing reassurance.
Whatever you bring to this office, this office has a habit of magnifying and pointing out and hopefully you correct for it.
"We are indisputably in a stronger position today than we were when I came in eight years ago", Obama said of his overall legacy.
He said: "My advice was campaigning is different from governing". "He's somebody who I think likes to mix it up and to have a vigorous debate". Absolutely, of course I've got concerns.
"The federal government and our democracy is not a speedboat". It's an oceanliner, as I discovered when I came into office.
He also suggested the Republican is coming to the White House "with fewer set hard-and-fast policy prescriptions than a lot of other presidents might be arriving with".
While he promised his administration is working with President-elect transition team, as he took questions from the press for the first time since the historic 2016 presidential election, Obama did issue reservations about Trump's temperament which have many at home and around the world uncertain.
