Li announced in November 2018 that he has entered into an agreement with the China Aerospace Science and Industry Corp. to build a new line of supersonic bullet trains. The plan is for the trains to run using newly developed technology. Li said, "Core technology can't be bought. The more you use others' technology, the more reliant you become. We have to innovate on our own. The journey will be tough but the prospects are promising."
In 2018, according to the Financial Times, Li has become Daimler's largest shareholder, with a 9.7% stake in the German automaker.
