President Donald Trump on Thursday cancelled the US delegation's scheduled trip to the World Economic Forum in Davos, Switzerland, a week after announcing that he would not attend the conclave if the political crisis that has resulted in the partial shutdown of the federal government were to continue.

"Because of the Democrats intransigence on Border Security and the great importance of Safety for our Nation, I am respectfully cancelling my very important trip to Davos, Switzerland for the World Economic Forum. My warmest regards and apologies to the @WEF!" tweeted Trump.

And White House Press Secretary Sarah Sanders said in a statement Thursday that "Out of consideration for the 800,000 great American workers not receiving pay and to ensure his team can assist as needed, President Trump has canceled his Delegation's trip to the World Economic Forum in Davos, Switzerland."

Treasury Secretary Steven Mnuchin had been scheduled to head the US delegation to the Davos Forum, which will run from Jan. 22-25, the White House had announced earlier this week.

Along with Mnuchin, the secretaries of State and Commerce, Mike Pompeo and Wilbur Ross, respectively, had been planning to travel to Davos, along with Foreign Trade Representative Robert Lighthizer and Deputy White House Chief of Staff Chris Liddell.

Trump warned last week that he would not go to Davos if the partial government shutdown, now in its 27th day without any prospect of a quick resolution and with the president intransigent on his demand that Congress approve $5.7 billion in funding to begin construction of his controversial US-Mexico border wall.

In all, about 70 heads of state and government and more than 300 ministers from about 100 countries will meet next week in the small town in the Swiss Alps that each year for a week becomes a high-security fortress with the most advanced security measures to guarantee the safety of the world leaders.

Last year, Trump attended the exclusive forum as well as in 2017 three days before taking office, becoming the first president-elect to show up at the event, at which he sparked considerable tension by delivering a very protectionist address.

Trump will not be the only noteworthy no-show this year at Davos, however, given that French President Emmanuel Macron announced several days ago that he will not attend because of the crisis in his country after several weeks of massive demonstrations by the so-called "yellow vest" protesters.
