A model of US President Donald Trump from the Madame Tussaud's waxwork attraction more than four miles away was placed outside the new embassy building, due to open for business on January 16, after the president's announcement.
"The US chancery in Grosvenor Square had aged beyond its ability to be improved to current security and life safety standards without extensive investment in infrastructure that would require appropriated dollars", he said.
The State Department, however, announced plans for relocating the London embassy in 2008, while George W. Bush was still president, because of concerns about security following the September 11 terror attacks.
U.S. President Donald Trump cancelled a trip to London scheduled for next month to open a new embassy, blaming Barack Obama for selling off the old one for "peanuts" in a bad deal.

Earlier, Israel's Prime Minister Benjamin Netanyahu said in the weekly cabinet meeting that UNRWA agency should gradually shut down.
President Donald Trump was expected to visit London in February - and now that his trip has been put on hold, many are at odds as to why.
Just south of the River Thames, the cube-shaped embassy building is in sight of Westminster and part of a £15 billion, 561-acre regeneration project set to transform one of the South Bank's last remaining industrial stretches.

It does not mean plans for the US President's state visit to the United Kingdom are off entirely, with a Downing Street spokesman telling the newspaper: "An invitation for a state visit has been extended and accepted".
Trump's cancellation was met with humour on social media, with parodies of the president's tweet trending on Twitter.
The mayor of London - who has been criticized by Trump in tweets - said Trump appeared to have "got the message from the many Londoners who love and admire America and Americans but find his policies and actions the polar opposite of our city's values of inclusion, diversity and tolerance".

His comments sparked criticism from Foreign Secretary Boris Johnson, who accused the Mayor of London of endangering the so-called "special relationship".
