A foreign analyst slammed a proposed tunnel project that could link the United States and Russia on Sunday, saying the proposed project "stretches the imagination to the breaking point."

On Friday, Reuters reported that Russian President Vladimir Putin's international investment envoy, Kirill Dmitriev, had proposed building an underground tunnel linking the U.S. and Russia. Dmitriev added that President Donald Trump's ally, Elon Musk and The Boring Company, could help facilitate the construction.

Dmitriev shared more details on his personal X account.

"@elonmusk, imagine connecting the US and Russia, the Americas and the Afro-Eurasia with the Putin-Trump Tunnel - a 70-mile link symbolizing unity. Traditional costs are $65B+, but @boringcompany's tech could reduce it to <$8B. Let's build a future together!" he posted.

Former Moscow Times journalist Charles Hecker slammed the idea during a new interview with Times Radio.

"It's [Dmitriev's] job to dangle really tantalizing business proposals in front of President Trump and in front of the American business community and say 'Look at all of the things that could be accomplished if the war would only come to an end,'" Hecker said. "That's an enormous 'if' at this point."

"This sort of project is beyond anybody's imagination," he continued.

He added that the project could face steep opposition from business owners in Russia.

"There are some Russian businesses that are saying, 'Look, all of these folks left when the going got tough. We don't want them back anymore,'" he said, referring to businesses that left Russia after the country invaded Ukraine. "We're doing this on our own. We're doing it without them. We have China. We have India. We have lots of other partners to do business with. We don't need the Americans."
