comments Moscow has proposed a 70-mile Elon Musk-built 'Putin-Trump' rail tunnel which would link Russia and America. The tunnel, which would go under the Bering strait, would unlock joint exploration of natural resources and 'symbolise unity', a Kremlin envoy said. The proposal has suggested using The Boring Company, a US tunnel construction company owned by Elon Musk, to construct the $8billion bridge. It comes as the Kremlin desperately tries to stop Donald Trump from providing crucial Tomahawk missiles to Ukraine. Kirill Dmitriev, President's Vladimir Putin's investment envoy and head of Russia's RDIF sovereign wealth fund, said Moscow and 'international partners', including Musk, could build the rail and cargo link in under eight years. While it would typically cost more than $65bn, Musk's firm's technology could reduce the cost to under $8bn, Dmitriev said. Dmitriev, who is behind a Russian charm offensive designed to revive US-Russian relations, floated the idea on Thursday after Putin spoke to Trump by phone and agreed to meet in Budapest to try to find a way to stop the war in Ukraine. 'The dream of a US–Russia link via the Bering Strait reflects an enduring vision — from the 1904 Siberia–Alaska railway to Russia's 2007 plan,' Dmitriev wrote on X.

The Bering Strait, which is 51 miles wide at its narrowest point, separates Russia's Chukotka region from Alaska. Ideas to link the two points have been around for at least 150 years, with various projects drawn up but never implemented. Dmitriev has forged ties with Steve Witkoff, Trump's special envoy, and spoken of the possibility of U.S. energy majors taking minority stakes in Russian projects in the Arctic. 'Imagine connecting the US and Russia, the Americas and the Afro-Eurasia with the Putin-Trump Tunnel - a 70-mile link symbolizing unity,' he wrote to Musk on X. He said a similar idea - to build a 'Kennedy-Khrushchev World Peace Bridge' - had been floated during the Cold War and published a sketch showing the route it might have taken between Chukotka and Alaska. 'RDIF has already invested in and built the first ever Russia-China railroad bridge. The time has come to do more and connect the Continents for the first time in human history. The time has come to connect Russia and the US,' said Dmitriev. Musk is yet to comment on the proposal.
