Britain's foreign office on Thursday announced new sanctions targeting individuals and entities it said were involved in the production or transport of Russian oil, facilitating military manufacturing and circumventing financial services sanctions.
The package also included 12 oil tankers that Britain says operate as part of Russia's shadow fleet and help Moscow evade sanctions on oil exports.
It also included three crypto exchanges and two payment platforms that Britain suspects Russia uses to circumvent financial sanctions.
Britain said two of those entities sanctioned had processed and facilitated transactions with the A7 illicit finance network.
Additionally, it included seventeen entities and individuals involved in the supply of goods deemed by the UK, US and EU to be vital for the Russian war effort, including Russia-based importers of machine tools, electronics and materials used to produce missiles and drones.
Russia's embassy in London did not immediately respond to Reuters' request for comment.
