The U.S. electric vehicle maker rolled out Full Self-Driving, or FSD, the most autonomous version of its Autopilot software, four years ago but has yet to make it available in China, its second-largest market globally, despite customers urging it to do so.
Musk said this month Tesla may make FSD available to customers in China "very soon", in response to a query on social media platform X.
Rival Chinese automakers such as Xpeng (9868.HK) have been seeking to gain an advantage over Tesla by rolling out similar software.
Musk is looking to obtain approval to transfer data collected in the country abroad to train algorithms for its autonomous driving technologies, the person said.
Tesla has since 2021 stored all data collected by its Chinese fleet in Shanghai as required by Chinese regulators and has not transferred any back to the United States.
Musk's itinerary on Sunday afternoon includes a meeting with Ren Hongbin, a government official who heads the China Council for the Promotion of International Trade, the organiser of the Beijing auto show currently underway, state media reported.
"It is good to see electric vehicles making progress in China. All cars will be electric in the future," Musk said in a video posted on social media by a user affiliated with state media.
Musk's trip came just over a week after he scrapped a planned visit to India to meet with Prime Minister Narendra Modi, citing "very heavy Tesla obligations."
The company said this month it would lay off 10% of its global workforce as it grapples with falling sales and an intensifying price war for EVs led by Chinese brands.
U.S. auto safety regulators said on Friday they had opened an investigation into whether Tesla's recall of more than 2 million vehicles in the U.S. announced in December to install new Autopilot safeguards was adequate following a series of crashes.
LANDED IN BEIJING
A Gulfstream private jet with tail number N272BG, which is registered to Falcon Landing, a company connected to SpaceX and Tesla, landed at Beijing Capital Airport on Sunday at 0603 GMT, according to Chinese flight tracking app Flight Manager.
The other jet registered under Falcon Landing is N628TS, which is Musk's main jet that he used to travel to China on his last trip nearly a year ago, when he met with Chinese government officials in Beijing and visited Tesla's Shanghai factory.
Tesla has sold more than 1.7 million cars in China since it entered the market a decade ago and the Shanghai factory is its largest globally.
Musk's visit coincides with the Beijing auto show, which opened last week and ends on May 4. Tesla does not have a booth at China's largest auto show and last attended in 2021.
Also on Friday, Grace Tao, Tesla's vice president in charge of external relations in China, published a commentary on the social media account of state media outlet People's Daily, arguing that autonomous driving technologies would be the new growth engine for EV industry.
Tao said in the article that Tesla was leading autonomous driving research and development with its "end-to-end neural network" technology and data collected from millions of cars on the road.
China's complicated traffic conditions with more pedestrians and cyclists than in many other markets provide more scenarios that are key for training autonomous driving algorithms at a faster pace, according to industry experts.
Musk said last week Tesla would introduce new, cheaper models using its current EV platforms and production lines and would offer a new "robotaxi" with self-driving technology. He said in a post on X this month that he would unveil the robotaxi on Aug. 8.
Tesla shares are down almost a third since the start of the year as concerns have grown about the EV maker's growth trajectory. Last week, Tesla reported its first decline in quarterly revenue since 2020 when the COVID-19 pandemic slowed production and deliveries.
