'America is back' - Biden touts muscular foreign policy in first diplomatic speech

US President Joe Biden on Thursday promised a new era after the scattershot foreign policy of his predecessor, Donald Trump, declaring "America is back" on the global stage in his first diplomatic address as president.

In his speech, Biden signalled aggressive approaches to China and Russia, urged Myanmar's military leaders to halt their coup, and declared an end to US support for a Saudi Arabia-led military campaign in Yemen.
