Just hours after taking office Joe Biden has already begun dismantling the Trump era after signing executive orders to re-join the Paris Agreement, force mask wearing and abolish the 'Muslim travel ban.'

Saying there was "no time to waste," the new US President signed 15 executive actions shortly after entering the White House on Wednesday afternoon, overturning some of Donald Trump's most controversial policies.

The orders included mandating masks on federal property, halting the withdrawal from the World Health Organization, re-joining the Paris climate accord and ending a travel ban on some Muslim-majority countries.

His very first order signed on Wednesday requires masks and physical distancing in all federal buildings as well as the development of a testing program for federal employees for Covid.

Biden's order, the first one he signed at the White House and just hours after taking office, says federal employees, contractors and others in federal buildings or on federal lands should "wear masks, maintain physical distance, and adhere to other public health measures, as provided in (Centers for Disease Control and Prevention (CDC) guidelines."

Biden directed agencies to "immediately take action...to require compliance with CDC guidelines" and for employees to wear masks and engage in social distancing.

He also signed an order immediately lifting a controversial travel ban on 13 Muslim-majority and African countries.

The US President halted the construction of the US-Mexico border wall and reversed a Trump order preventing migrants who are in the United States illegally from being counted for congressional districts.

Biden also signed a memorandum directing the Department of Homeland Security (DHS) and the U.S. attorney general to preserve the Deferred Action for Childhood Arrivals (DACA) program, which protects migrants who came to the country as children from deportation.

In another sign of the stark differences between his presidency and the last, he reversed Trump's executive order calling for stricter immigration enforcement away from the country's international borders.

Immediately after the actions were announced, the Department of Homeland Security said it would end all enrolments in a controversial Trump program - known as the Migrant Protection Protocols - that forced more than 65,000 asylum seekers back to Mexico to wait for U.S. court hearings.

The release did not clarify what will happen to migrants currently in the program, many of whom have been stuck for months in squalid tent camps near the southwest border.

Biden's decision to immediately roll back Trump's travel ban won praise from business groups and migrant advocates.

Myron Brilliant, the head of international affairs at the U.S. Chamber of Commerce, said the ban was "was not aligned with American values" and its reversal would help "restore our credibility on the global stage."
