MOSCOW (Reuters) -Russian President Vladimir Putin offered the U.S. the opportunity for joint exploration of the country's rare earth metals deposits, as well as the supply of aluminum to the U.S. domestic market, under a future economic deal.

Russian President Vladimir Putin moved to undercut U.S.-Ukraine negotiations over a critical minerals-sharing agreement, offering an alternate supply deal for valuable elements such as titanium, lithium and beryllium.

Russian President Vladimir Putin said he is open to offering the US access to rare minerals, including from Russian-occupied Ukraine. This comes after US President Donald Trump has repeatedly pushed for Ukraine to give up some of its minerals in exchange for support, in a deal which is currently being finalised, according to a Ukrainian minister.
