Chinese artificial intelligence company SenseTime Group postponed its $767 million Hong Kong initial public offering on Monday, after the U.S. government added it to an investment blacklist. SenseTime has denied accusations against it, calling them "unfounded." Reacting to this, Liu Baocheng, dean of the Center for International Business Ethics at the University of International Business and Economics, stressed that the world should stand together and defend sovereign rights against U.S. "long arm" intervention into business and geopolitical decisions.
