US President Donald Trump is aiming to be the best salesperson for American economic interests when he goes to Davos later this week, the White House said Tuesday. Trump is set to speak Friday at the World Economic Forum, an annual gathering of the global pro-trade elite at the Swiss ski resort, in a move that has raised eyebrows because of his protectionist America First policies. We are going to the World Economic Forum to share President Trumps economic story and to tell the world that America is open for business,said Trumps chief economic adviser Gary Cohn. We want the world to invest in America and to create jobs for hard working Americans,he continued, adding that Trumps economic agenda focused on aggressive deregulation and corporate tax cuts had unleashed the US economy.
