The signature of a protocol by UzAtom's Directorate for Construction of a Nuclear Power Plant and JSC Atomstroyexport - the engineering division of Russia's Rosatom - means work can begin at the site of Uzbekistan's first nuclear power plant.
Russia's President Vladimir Putin has said the country should consider whether to bring in some restrictions on exports of raw materials such as uranium, titanium and nickel, in response to sanctions limiting imports of certain goods.
Rosatom has said that its work to resolve nuclear legacy issues in Russia's Far East has been successful, including the dismantling of dozens of decommissioned nuclear-powered submarines.
A draft plan including as many as 34 new nuclear power units in Russia by 2042 has been published for public consultation - they are a mix of large and small reactors, and include replacement of existing units as well as new locations.
