President Donald Trump has swung into action and has continued to cancel some Obama’s administration policies in order to fulfil his campaign promises.
He has signed an executive order to withdraw from the Trans-Pacific Partnership (TPP). The 12-nation trade deal was a linchpin of former President Barack Obama’s Asia policy.
“Great thing for the American worker what we just did,” said Mr Trump as he dumped the pact with a stroke of a pen.
He also cut funding for international groups that provide abortions, and froze hiring of some federal workers.
Mr Trump’s executive order on TPP was largely symbolic since the deal has not been ratified by a divided US Congress.
During his presidential campaign, he criticised the accord as a “potential disaster for our country”, arguing it harmed US manufacturing.
His action won some plaudits from the left as well as the right.
Democratic Senator Bernie Sanders told the BBC he backed it because trade deals like this have been a “disaster” and cost millions of jobs.
The Trump administration’s first weekday began with a flurry of executive orders, which allow the president to bypass Congress by issuing legally binding directions, mostly of limited scope, to federal agencies.
Mr Trump also signed an order blocking foreign aid or federal funding for any nongovernmental organisation that provides abortions abroad.
The so-called Mexico City policy was first established by Republican President Ronald Reagan in 1984.
It is typically rescinded by incoming Democratic presidents, including Barack Obama in 2009, and reinstated by Republican presidents.
Mr Trump also signed an executive action placing a hiring freeze on non-military federal workers.
After meeting business leaders earlier at the White House, Mr Trump pledged to lower corporate taxes to 15% or 20%, from the current 35%, and slash regulations by up to 75% if they keep jobs in the US.
Mr Trump – whose protectionist rhetoric sent the US dollar falling – also met labour leaders later on Monday.
Some of the measures he announced on Monday fulfil “Day One” pledges he made as a candidate in a speech in Gettysburg in October.
But perhaps inevitably, some of the promises he made on that day and at rallies during his campaign have not been kept, although he may get to them in the coming days and weeks.
