(Reuters) -Autonomous trucking startup TuSimple Holdings Inc, backed by Chinese social media firm Sina Corp, is looking to sell its business in China and focus on the U.S. market, sources said.
The decision comes after the startup reached an agreement with the U.S. government to restrict the China unit's access to data due to U.S. security concerns.
TuSimple, which raised more than $1 billion through an initial public offering (IPO) on Nasdaq last April, said in its annual report that it operates about 100 Level 4 autonomous semi-trucks - 75 in the United States and 25 in China - capable of running without human drivers on certain routes.
The company hopes to sell the China unit for up to $1 billion, and has approached several Chinese investors, including private equity firm Boyu Capital, in its search for potential buyers, according to one of three people who confirmed TuSimple's plans to sell, but declined to be named as they were not authorised to speak to media.
The decision to sell the China business was the result of "tight regulations" in China and the United States, said this person, adding the TuSimple business was expected to "grow independently" after resolving the security concerns.
When contacted by Reuters, TuSimple declined to comment on whether it had plans to sell its China division. Boyu and Sina did not respond to requests for comment.
Shares in San Diego-headquartered TuSimple jumped 22.4% on Wednesday.
Founded by two veteran Chinese entrepreneurs, TuSimple employs around 500 people and holds several patents in China.
TuSimple posted $732.7 million in losses last year, and said it had not "recognised a material amount of revenue" to date.
It has partnered with big package delivery firms such as DHL Worldwide Express and United Parcel Service Inc in the United States.
Regulators in China and the United States have put companies operating in both countries under sharper data security scrutiny in recent years.
Tighter cybersecurity laws in China have made it difficult for companies to transfer data collected there to another country.
While it appears highly unusual for a Chinese-promoted firm to sell up in China, there are several factors that could have swayed TuSimple's decision to focus on the U.S. market.
Last month, TuSimple said it had entered into an agreement with the U.S. government to "limit access to certain data and adopt a technology control plan", and that two directors representing Sun Dream Inc, a Sina affiliate, would leave when their term ends.
TuSimple revealed in its IPO prospectus last year that Sina's investments in TuSimple had been put under review by the Committee on Foreign Investment in the United States (CFIUS).
TuSimple also said that it had agreed to periodically report to CFIUS through a government security committee to resolve U.S. authorities' security concerns.
Failure to address such concerns would have resulted in the United States ordering Sina to divest its stake in TuSimple, according to TuSimple's IPO prospectus.
Geo-political and economic tensions between Beijing and Washington have already resulted in a sharp slowdown in Chinese investments and fundraising in the United States, with some Chinese firms also facing the prospect of being delisted by U.S. stock exchanges.
One source said TuSimple had decided to sell its China business as some U.S. states were more amenable to developing self-driving trucks for public roads and highways.
TuSimple's operations in China were mainly focused on transportation at ports, as China allows limited public routes for autonomous driving vehicles to conduct road tests.
In December, TuSimple announced the completion of the world's first trip by a fully autonomous semi-truck travelling at 80 miles on public roads in Arizona.
