Moroccan traveling to Korea

I have a Moroccan friend who wants to travel to Korea.  They were told by a friend that immigration will ask if they have a certain amount of money ($1000) before they can enter the country.  Have any Moroccan's or others experienced this? It seems like total BS to me.

Doesn't sound correct. They may want you to give the reason for visit and proof of residence here. Hotel, etc.
