Who is AIA under?

Could you please clarify what you mean by "AIA under?" Are you referring to the AIA Group, a multinational insurance company, or some other entity named AIA? Assuming you're asking about the AIA Group, it's not typically described as being "under" another entity in the traditional sense. However, it's worth noting that AIA Group is listed on the Hong Kong Stock Exchange and is part of a larger financial services conglomerate. Additionally, AIA Group operates in multiple countries and regions around the world, often partnering with local companies or institutions to provide insurance and other financial services. If you're looking for more information about AIA Group's ownership structure or parent company, I recommend checking out their official website or financial reports for more details.
