Anthony Scaramucci, who is part of Donald Trump's Presidential Transition Team, also said Trump wants to re- organise NATO to better reflect the current global political climate.
Besides, he said the US would want to have a "phenomenal relationship" with China.
"Donald Trump is in touch with the working class, while elites are not," he said in an apparent dig at what he termed as "global elite" attending the annual Davos meeting of the World Economic Forum (WEF).
"We may not like the way Donald Trump communicates here, but he communicates to a large population.

"Donald Trump loves people -- this is what you want in the US President," Scaramucci said.
In the United States, he said, eight million people have gone from working class to working poor and there is a need to come up with policies to change that.
Scaramucci, a hedge fund manager and Skybridge Capital founder, said the new government will focus on growth and spreading benefits beyond the elites through infrastructure spending, overhauling tax laws and less regulations.
Days before Trump assumes office, Scaramucci also asserted that the Federal Reserve's independence will be upheld but cautioned policy markers about dollar appreciation.
He said that if things play out the way we would like it to, there would be better-than-expected growth, a simpler tax code, an invigorated middle class and working class, where purchasing power goes up.
The virtuous circle of consumption will take place and growth will solve many of the problems that are on the table, he added.
"NATO (North Atlantic Treaty Organisation) is working but there are things about it that need to change and there are parts of it that are, in the words of Trump, 'obsolete'", he noted.
"We have to think about changing the (NATO) treaty to front face the 21st and 22nd centuries," he added.
