Can foreigners buy at auctions?

Thanks. I got mixed replies from different people. Most said no. Info on the internet is mixed as well. I also don't know any examples of foreigners buying from auctions.

I understand that all foreigner property purchases need to be approved by the State governments. Would you know how that works for auction purchases? Transactions can be voided if they are eventually not approved by the State? Thanks. 🙇🏻
