An investment envoy for Russian President Vladimir Putin on Friday entreated Elon Musk and his tunneling business, the Boring Company, to commit to building an undersea rail tunnel through the Bering Strait to be partly funded by Moscow. Kirill Dmitriev, who is head of Russia's sovereign wealth fund, said in posts on Musk's social media platform X that he envisioned "the Putin-Trump Tunnel - a 70-mile link symbolizing unity." A tunnel like this would traditionally cost an estimated $65 billion to build, Dmitriev said, adding that The Boring Company and its technology could potentially reduce those costs to $8 billion and complete the project within eight years. "Let's build a future together!" he wrote. Dmitriev's suggestion followed a call between Putin and President Donald Trump on Thursday, during which plans were made to discuss possible resolutions to the Ukraine War. Trump said Secretary of State Marco Rubio and other high-level advisors will meet next week with a Russian delegation before Trump and Putin meet in Budapest, Hungary, at a future date.
