The UK plans to phase out Russian oil imports by the end of the year after Washington banned imports of Russian oil and gas into the US in an attempt to deprive Moscow of revenue over its invasion of Ukraine.

The announcements open a new front in efforts to isolate Moscow from the global economy following moves to impose sanctions on critical Russian banks, top government officials and oligarchs, as well as its central bank.

The EU did not follow suit and instead unveiled a plan to cut Russian gas imports by two-thirds within a year. But a ban on US and UK imports will be far less disruptive to global markets than a full international embargo as only a small proportion of Russian shipments goes to those markets.
