President Donald Trump took an opportunity to address world leaders on Tuesday to trumpet his "America First" agenda and encourage other nations to adopt a similar nation-focused approach to economics and political relations around the world.

"America's newfound prosperity is undeniable, unprecedented and unmatched anywhere in the world," Trump said at the World Economic Forum in Davos, Switzerland, hours before his impeachment trial was set to begin in earnest back home. "America achieved this stunning turnaround not by making minor changes to a handful of policies, but by adopting a whole new approach centered entirely on the well-being of the American worker."

"Every decision we make on taxes, trade, regulation, energy, immigration, education and more is focused on improving the lives of everyday Americans," the president added. "Only when governments put their own citizens first will people be fully invested in their national futures."

The multiday forum in Davos is an annual event where the globe's most powerful political leaders and corporate executives share ideas in the Swiss Alps.

Much of Trump's speech focused on the success the administration has seen while pursuing an "America First" policy, a set of guidelines that tries to benefit average Americans through economic policies such as trade protections or tax cuts.

The policy, which has led to fierce trade battles with longtime economic partners like China, the EU and Mexico, has accompanied better-than-expected GDP growth in the U.S. as well as an unemployment rate under 4% and consistent records in the stock market.

Though bilateral trade deliberations have roiled financial markets for the better part of two years, the White House reached two key trade deals last week that officials say will boost the economy and sent the S&P 500 above 3,300 for the first time ever.

The U.S. and China signed on Wednesday a "phase one" trade deal that officials say will lead to an increase in sales of American goods and services to Beijing and ease the two-year dispute between the globe's two largest economies.

On Thursday, the Senate passed a new North American trade deal that grants U.S. producers greater access to Canadian dairy markets and creates stricter rules for auto parts rules of origin.

In his speech, the president also pointed to one of the administration's biggest legislative wins, the 2017 Tax Cuts and Jobs Act, which lowered the corporate tax rate to 21% and buoyed business profits for much of Trump's presidency.

The administration argues that the promise of lower tax rates entices global businesses to shift more production to the U.S. and employ more Americans.

"Today I urge other nations to follow our example and liberate your citizens from the crushing weight of bureaucracy," Trump said. "With that, you have to run your own countries the way you want."

The president did not address ongoing trade deliberations with the EU or member nations despite reports that he and French President Emmanuel Macron reached an agreement in their dispute over digital taxes.

Trump's speech came a day after the president's legal team implored the Senate to reject the House's two articles of impeachment against him. The third presidential impeachment trial in U.S. history will begin later Tuesday.
