Tesla Inc Chief Executive Elon Musk flew out of Shanghai on Thursday morning, wrapping up a two-day trip to China in which he met government ministers, a key battery supplier and visited the automaker's biggest production hub.

Photos of Musk's visit to Tesla's Shanghai factory late Wednesday showed him holding up a "Giga Shanghai" sign, flanked by hundreds of staff including head of global manufacturing Tom Zhu.

"A very rewarding day!," Grace Tao, Tesla's China-based public affairs chief, said in a social media post with the photos.

Earlier in the trip, Musk met with China's foreign, commerce and industry ministers in Beijing where he also dined with the chairman of battery supplier Contemporary Amperex Technology.

Since his arrival in China on Tuesday morning, the US billionaire has been showered with praise from the Chinese public but Musk himself has been uncharacteristically silent and has yet to make any public statements.

Little is known of the conversations he had with Chinese government officials so far.

The industry ministry only said Musk and its head exchanged views about development of electric vehicles and connected cars, while the commerce ministry announced he discussed Tesla's development in China with its minister. (Reuters)
