Kyiv, 03 April (BBC)- Frozen Russian assets should be used to rebuild Ukraine after the war, the governor of Ukraine’s Central Bank has told the BBC.

Kyrylo Shevchenko called for an extensive list of extra sanctions, from cutting card payments to suspending Russian access to the IMF.

Every day that sanctions are delayed "is costing the lives of civilians and children", he said in an interview.

For security reasons, he answered questions sent by email.

Mr Shevchenko, governor of the National Bank of Ukraine, said that Russia should eventually be made to pay to repair the damage caused during the invasion.

“The need for money will be huge,” he told the BBC. “It could be fulfilled through loans and grants from multinational organisations and direct help from other countries. However a large share of financing is needed to be obtained as a reparation from the aggressor, including funds that are currently frozen in our allied countries.”

Much of Russia’s $630bn of foreign exchange reserves are thought to be held outside the country, and effectively frozen by sanctions in the US, the EU and other places.

That would make billions available for reconstruction – if Ukraine is able to access it once the war is over.
