It could happen.
I’m not familiar with an agreement among scientists not to clone humans, but there are reasons not to. Scientists do clone human tissue (therapeutic cloning), but probably no one has succeeded in reproductive human cloning–ie, making a human baby with 100% a donor’s DNA, or somatic-cell nuclear transfer.
(Reader poll: Do I still have to mention Raelians when I talk about human cloning? Or can we all just assume that they lied when they said they had successfully cloned a person and now we can all forget about it?)
Wikipedia has a list of laws about human cloning, although the US section needs to be updated. Here’s a good article called What Ever Happened to Cloning? published in August 2016.
Humans and primates are very difficult to clone and there doesn’t seem to be a market incentive to do it. Furthermore, there would be some public backlash to overcome. Some criticisms of human reproductive cloning are practical (the cost, difficulty, and high chances that something could go wrong) and some are more philosophical (playing God) and some are plain science fiction (“we might accidentally start harvesting clones for organs.”)
