Russian President Vladimir Putin speaks during a news conference.

:: President Vladimir Putin said the United States would have to cut its diplomatic staff in Russia by 755 people and that Moscow could consider additional measures against Washington as a response to new US sanctions approved by Congress.

Moscow ordered the United States on Friday to cut hundreds of diplomatic staff and said it would seize two US diplomatic properties after the US House of Representatives and the Senate overwhelmingly approved new sanctions on Russia. The White House said on Friday that US President Donald Trump would sign the sanctions bill.

Putin said in an interview with Vesti TV released on Sunday that the United States would have to cut its diplomatic and technical staff by 755 people by Sept. 1.

“Because more than 1,000 workers – diplomats and support staff – were working and are still working in Russia, 755 must stop their activity in the Russian Federation,” he said.

The new US sanctions were partly a response to conclusions by US intelligence agencies that Russia meddled in the 2016 US presidential election, and to punish Russia further for its annexation of Crimea from Ukraine in 2014.

Russia’s response suggested it had set aside initial hopes of better ties with Washington under Trump, something the Republican president, before he was elected, had said he wanted to achieve.

A federal law enforcement investigation and multiple US congressional probes looking into the possibility that Trump’s campaign colluded with Russia have made it harder for Trump to open a new chapter with Putin. Russia denies it interfered in the election and Trump has said there was no collusion.

Moscow said on Friday that the United States had until Sept. 1 to reduce its diplomatic staff in Russia to 455 people, matching the number of Russian diplomats left in the United States after Washington expelled 35 Russians in December.

On Friday, an official at the US Embassy, who did not wish to be identified, said the embassy employed about 1,100 diplomatic and support staff in Russia, including Russian and US citizens.
