Britain on Monday announced what it said was its largest package of sanctions against Russia since the early days of the war in Ukraine.
The sanctions also apply to companies worldwide that supply components used by the Russian military.
Foreign minister David Lammy made this announcement on Monday.
Lammy said the package, timed to mark the third anniversary of the Russian invasion, also targeted North Korea’s defence minister No Kwang Chol over the deployment of North Korean forces in Russia, and Kyrgyzstan-based Keremet Bank.
He added that the sanctions also affected producers and suppliers of machine tools, electronics and dual-use goods including microprocessors used in weapons systems.
These were based in a range of third countries including Central Asian states, Turkey, Thailand, India and China.
It was gathered that among a list of wealthy Russians included in the sanctions was billionaire businessman Roman Trotsenko.
Britain also sanctioned a further 40 vessels Britain said were being used to help Russia evade sanctions by transporting its oil.
“Every military supply line disrupted, every trouble blocked, and every enabler of Putin’s aggression exposed is a step towards a just and lasting peace,” Lammy said.
