U.S. President Joe Biden on Friday drew a sharp contrast with the foreign policy of his much-derided predecessor, Donald Trump, and urged democracies to work together to challenge abuses by autocratic states such as China and Russia.

In his first big appearance as president on the global stage, an online "virtual visit" to Europe, Biden sought to re-establish the United States as a multilateral team player after four years of divisive "America First" policies under Trump.

Speaking to the Munich Security Conference, Biden drew a stark contrast with the more transactional foreign policy of Trump, who angered allies by breaking off global accords and threatening to end defense assistance unless they toed his line.
