Tesla CEO Elon Musk concluded his China trip this week after visiting Beijing and Shanghai. The billionaire remained tight-lipped on Twitter, which he acquired last year, about his conversation with Chinese officials.

This week's trip to China was Musk's first in three years, which became a two-day whistle-stop tour.

Musk Treats Tesla Workers

He concluded his trip by treating around 100 workers at Tesla's Shanghai plant to burgers and soft drinks before heading towards his private jet in Shanghai's Hongqiao airport Thursday bound for the United States.

While Twitter is banned in China, the Chinese state-run media site Global Times posted a video on Twitter where Musk thanked the factory's workers for staying up late at night.

"I would like to just very much congratulate you on the amazing work that you've done," he told the crowd. "I just wanna let you know it warms my heart."

Tesla's China vice president Grace Tao also posted a picture on the Chinese social media site Weibo showing Musk waving to the camera with the workers in Shanghai.

Meeting with Chinese Officials, Businessmen

Earlier in his trip, Musk traveled to Beijing and received a hero's welcome as a "global idol" similar to business magnate Jack Ma.

His trip included several meetings with top government officials like Chinese vice premier Ding Xuexiang. Ding ranked sixth within the Chinese Communist Party's Politburo Standing Committee, which is led by President Xi Jinping. The meeting marked the first time Ding was known to privately converse with a foreign CEO.

Musk initially had a one-on-one meeting with then-premier Li Keqiang in 2019.

He also attended a banquet with battery boss Zeng Yuqun of Contemporary Amperex Technology (CATL).
