President Donald Trump is expected to push his "America First" agenda and try to convince a sceptical gathering of political and business leaders at the World Economic Forum that he is good for business.
The President is expected to pitch America as economically resurgent and the place to do business, during his keynote address in Davos, Switzerland, later.
Mr Trump is expected to claim that his business-friendly tax reforms and determination to tear up regulation have brought prosperity and a booming stock market.
"I think the real message is we want great prosperity and we want great peace," said Mr Trump on the eve of his speech.
"A lot of people are coming back to the United States. We are seeing tremendous investment."
On Thursday, Mr Trump promised a "tremendous" increase in trade with the UK at a short meeting with Theresa May in Davos.
The US President sought to build bridges with the Prime Minister in their first meeting since a diplomatic row over his re-tweeting of Britain First posts.
Speaking during a photo opportunity, Mr Trump said the US and UK are "very much joined at the hip".
He boasted of a "really great relationship" with Mrs May and being "on the same wavelength in, I think, every respect".
Mr Trump told her: "It's great to see you. One thing that will be taking place over a number of years will be trade.
"Trade is going to increase many times and we look forward to that."
Mr Trump added talks would soon take place and "are going to lead to tremendous increases in trade between our two countries, which is great for both in terms of jobs".
"We look forward to that and we are starting that process pretty much as we speak."
Both leaders said they would "talk about" his mooted state visit to the UK, but gave no clues about when it would take place.
Shaking hands with the US President after their bilateral meeting, Mrs May said they had enjoyed a "great discussion" about the prospects for improved trade relations.
"We continue to have that really special relationship between the UK and the United States, standing shoulder to shoulder because we are facing the same challenges across the world," she said.
"As you say, we are working together to defeat those challenges and to meet them. And alongside that, working for a good trade relationship in the future which will be to both our benefits.
"So the UK and the US both do well out of this."

Downing Street later said both leaders asked officials to "finalise the details" of a visit by Mr Trump's to the UK by the end of 2018.
One had been expected, but the timing was thrown into question when the US President cancelled a trip to open the new US embassy in London in an "off location".
