Donald Trump has said the US is "open for business and competitive once again".
Addressing world leaders at the World Economic Forum in Davos, Switzerland, the US president said: "The world is witnessing the resurgence of a strong and prosperous America."
The gathering of global elites with a free trade penchant had viewed Mr Trump with scepticism, given his "America First" message, but the White House has insisted his protectionist policies and international co-operation can go hand-in-hand.
Mr Trump outlined his work to overhaul the US tax system and slash regulations, adding: "America is the place to do business."
He said his work is beginning to pay dividends, pointing to 2.4 million jobs created since his 2016 election and noting that companies like Apple are planning to invest billions in the US.
The president added he is making progress on giving Americans the dream of a "great job, a safe home" and a "better life" for their children.
Mr Trump said he is willing to negotiate trade deals individually or as a group with the countries that remain in a trans-Pacific agreement he pulled the US out of after taking office.
He told delegates trade needs to be fair and reciprocal, and he will negotiate "if it is in the interests of all" sides.
His speech drew a muted response. He received some applause when he took the podium, but many in the audience kept their hands at their sides.
As he showcased his economic agenda, the audience kept quiet, with no pockets of clapping that other leaders might receive. He received polite applause when his speech ended.
