"If two Chinese scientists are to be believed,
China nearly made the first hybrid decades earlier. In 1967, they came close to creating a human-chimpanzee hybrid—and if the experiment hadn’t been shut down early, they would have succeeded.
Two scientists from Shenyang have claimed that they participated in an experiment in which they successfully impregnated a female
chimpanzee with human sperm. Their goal was to create a new, more highly evolved chimpanzee with a larger brain and a wider mouth. Ultimately, they hoped that their new creature would be able to speak.
The humanzee wasn’t exactly going to be treated well. Their plan was to use it as a slave by making it drive carts and herd sheep. They also wanted to send it off on experiments in space.

The project fell apart because of the Cultural Revolution. Zealous revolutionaries smashed their lab and destroyed their work, and the chimpanzee died before she could come to term. The researchers claim that she was already three months pregnant.
In 1981, the scientists said that they planned to try again. Nothing ever came of it, though, likely because of the growing concern about human ethics."
Wonder if they gave chimp the D or used articifial methods
