The upstart carmaker said in December it would invest $1 billion to build a 3-million-square-foot plant in the Nevada suburb of North Las Vegas.

In turn, the state has signed off on $215.9 million in tax incentives to lure the carmaker to the area.

However, the state treasurer, Dan Schwartz, has asked Faraday Future for about $75 million as security amid concerns about the Chinese corporation, Leshi Internet Information and Technology.

Leshi is a publicly traded company in China, and is associated with a Chinese media company called LeEco — Faraday Future's business partner. LeEco is formerly known as LeTV.

That $75 million request is likely justified, according to Thilo Hanemann, a China foreign investment expert at The Rhodium Group.

"Parties tend to ask for a higher risk premium because the political dynamics and regulations are so complicated on the Chinese side," he told Business Insider.

The Las Vegas Review-Journal reported on Thursday that Faraday Future executives sent a letter to Nevada state officials this week, promising to obtain a performance bond of up to $75 million — and adding another $13 million to go toward infrastructure at the site of the factory.

The bond comes after Schwartz — who's responsible for signing off on hundreds of millions of dollars in financial incentives for Faraday — became concerned after trading in shares of Leshi were suspended in December.

The trading was purportedly suspended to allow the company to incorporate a film company into its listing, according to The Guardian, which noted that such a move isn't uncommon in China.

Still, the suspension sparked Schwartz's concerns about the investor.

Leshi stock was expected to resume trading on March 7, but it's now being pushed back to May 7, according to a statement from Leshi that was obtained by Business Insider.

Schwartz added that "it could just be taking longer than anticipated, or there could be other reasons."

Nevada's state treasurer isn't the only person who's been concerned about Leshi. The Guardian's Mark Harris talked to former executives of Faraday Future who described early relations at Faraday Future and LeTV/LeEco as something of a "culture clash":

At one point, LeTV managers proposed calling the new company Fara Faro instead of Faraday Future. “The Americans were like, ‘That is the stupidest name ever,’” remembers an executive. “You had an international team that was experienced and open, juxtaposed with Chinese management that didn’t understand the US market and kept deferring to LeTV.”

Despite this tension, the company appears to be forging ahead. Just this week, Faraday Future announced that it received its first US patent. The patent is for a power inverter that Faraday says will manage its car's electric power "20 to 30% better" than its competitors. It's one of more than 100 US patents Faraday Future has submitted in the past year, the company said on its blog.

Hanemann, the China foreign investment expert, believes Faraday Future and LeEco see their investment in Nevada as an opportunity to "reach a big consumer market in the US, and access a diverse and talented workforce."

Faraday Future says its Nevada factory will create 4,500 jobs. If the plant materializes, that's good news for North Las Vegas, which was nearly insolvent just a couple years ago.
