The Kremlin demanded that the United Kingdom and other countries unfreeze Russian foreign assets without any conditions, as Western allies of Ukraine load economic pressure onto Moscow over the conflict.
"Britain and other countries that encroached on Russian assets are obliged to unfreeze them immediately without any conditions,” Moscow spokesperson Dmitry Peskov told reporters on Friday.
“Otherwise, they violate all the norms and rules of both their domestic legislation and international law," he added.
Some background: The United States and its allies have blocked or seized $58 billion worth of assets owned or controlled by sanctioned Russians in the past year, in an effort to crunch Russia's economy amid the war.
The Russian Elites, Proxies and Oligarchs (REPO) Task Force said in March that they will "redouble" their efforts to punish Russian President Vladimir Putin and his associates.
REPO is a joint effort between the US, Australia, Canada, Germany, Italy, France, Japan, the UK and the European Commission. It was established last year in order to monitor sanctions evasion.
