Who owns AIA Hong Kong?

Could you clarify for me who exactly holds ownership over AIA Hong Kong? I'm curious to know if it's a private individual, a group of investors, or perhaps an international insurance company that's behind this organization. Additionally, are there any publicly available sources that could shed light on the ownership structure and any potential changes in ownership over time? It would be greatly appreciated if you could provide me with a concise yet informative answer to this question.
