"The UK is increasing the number of sanctions and will pass new laws on a range of trade restrictions next week, with more coming next month," the statement said.
Earlier, the UK, as part of new sanctions, banned the use of pounds sterling and banknotes of EU countries in Russia.
In addition, new restrictions will affect the export of jet fuel and fuel additives to Russia.
Truss said that London would impose new anti-Russian sanctions until Russia withdraws its troops from Ukraine.
