Question about China's one child policy

This should have a factual answer. I was wondering about the details of China’s one child policy in working practice. Ok, here’s the scenario we are talking about:

A Chinese family moves abroad and has more than one child. What happens if they decide to return to China to take up residence again? Is the one child ‘violation’ not a violation since it occured on foreign soil? Is it something they may face a sentence of some sort for?

Enlighten me!

Thank you,

Wikipedia’s article on the one-child policy has the following sourced claim:

Wow, thanks!!!

Note also that the punishment for a violation is you have to pay a fine. It’s substantial, I understand, but you don’t go to jail for it.

When I lived there, I believe it was 10,000 Yuan, which was about $1200 at the time(quite a bit for most Chinese people). I believe it has doubled since.

I worked with wealthy Chinese people who had multiple kids and paid the fine. They were fine.
