Ma Xiaoguang, a spokesman for China's Taiwan Affairs Office, said Taiwan independence was "doomed to fail".
"Fraught with the 'two Chinas' separatist fallacy and confrontational thinking, the speech exposed the evil intentions to contain the mainland with the help of anti-China forces in the West," Ma said in a statement late on Wednesday.
Taiwan's ideology will overtake China, not the other way around. Xi is doomed. The Chinese Communist Party is doomed. All dictatorships that suppress grassroots democracy are doomed.
