A gene-edited monkey most prone to the disorder was selected as a donor, and its fibroblasts were used to make five cloned monkeys, Xinhua said, citing National Science Review, a Chinese journal.
The official China Daily said the clones would pave the way for more research into such problems in humans, which have become a major mental health concern.
The cloned monkeys already show signs of "negative behaviour", including sleep disorders, as well as elevated levels of anxiety and "schizophrenia-like behaviours", the paper added.
Xinhua said the programme, supervised by the institute's ethics panel, was in line with international ethical standards for animal research.
