It is unethical for a person having a fiduciary duty to place their own interests ahead of those to whom the duty is owed.
If/When Li directs money to LQMT for the purpose of advancing his own interests, he will be acting unethically with regard to his Chinese investors. To act ethically, he will need to make certain that LQMT doesn’t get one penny more than it would have gotten if he didn’t have a conflict of interest (by owning shares of LQMT and the MAZE). Given the reasons for not directing money to LQMT in the previous post, the only reason to do so is because of Li’s self interest in LQMT. If he manages to act ethically, the amount of money directed to LQMT isn’t going to be significant enough to get LQMT relisted IMO.
