Which country is Huobi exchange based?

Could you please enlighten me on the geographical location of the headquarters of the Huobi exchange? I'm particularly interested in understanding which country this leading cryptocurrency exchange platform is based in. I've heard much about its global influence and services, but I'm curious to know the specific nation that serves as its home base. Your insight into this matter would greatly assist me in my research on international cryptocurrency exchanges. Thank you for your time and attention.
