In 2015, Queen Elizabeth accompanied Chinese President Xi Jinping in a gilded, horse-drawn carriage to Buckingham Palace, during a visit that was supposed to symbolize "a new golden era" of closer economic ties between this former empire and the ascendant power in the east.

"The relationship between China and the United Kingdom is now truly a global partnership," the queen declared during a state banquet.

British Prime Minister Theresa May has launched a blistering attack on what she called Russia's efforts to "sow discord in the West," putting Moscow on notice: "We know what you are doing and you will not succeed."

In what is being described as a major foreign policy address delivered at the Lord Mayor's Banquet at Mansion House in London on Monday, May said Russia was waging "a sustained campaign of cyber-espionage and disruption."
