Jia, who is thought to be in the US attempting to build his Los Angeles-based electric car company, was added to a national blacklist of debt defaulters by Chinese courts this month over hundreds of millions in unpaid loans.
State news agency Xinhua said it is the second time regulators have ordered Jia to return to China after he apparently disregarded an order in September.
The Beijing branch of the China Securities Regulatory Commission "orders you to return to China before December 31, 2017," an announcement on the regulator's website said Monday.
Troubled conglomerate LeEco was founded in 2004 by Jia as an online video streaming platform, but in recent years Jia borrowed heavily to push the tech company into a slew of new business lines from gaming to sports to cars.

He publicly pledged to take on American tech stalwarts and held a lavish US market launch event in Silicon Valley last year to make known LeEco's ambitious expansion plans.
He also raised millions from mom and pop investors in loosley regulated private financing deals and ploughed the money into LeEco's privately held businesses.
