Are there any modern defacto Suzerainties?
I was reading on wikipedia about Suzerainties, where one state or territory controls another state or territory but allows the vassal to have internal autonomy (as I understand it). It claims that because 20th and 21 century law makes sovereignty a binary status, there are no modern de jure suzareinties, but the article allows for de facto Suzareinties.
The article seems to only discuss historical examples, though it includes some in the 20th century examples such as British Hong Kong.
What are some modern, 21 century examples of suzerainties in effect, that aren't legally considered suzerainties, if any? I realize it will be somewhat a matter of interpretation if it's true that there's no legal room for the concept of a suzerainty today, but I'm curious if there's anything that's close.
