Suppose I live in a constitutional parliamentary democracy & I do not believe in democracy. I'm also rich, could I fund a political party to partition the country (it has many uninhabited islets). So that I acquire a small island & change it into another sovereign country (a microstate like Monaco or the Vatican City) & crown myself as absolute monarch (King) via a treaty like the Lateran Treaty

Finally after receiving the said island, could I just contact a superpower like China, to install a military base on there

In exchange for their protection, I would negotiate shares in their governmental companies, funding of all my royal budget/financial expenses and lifestyle (including my official crowning ceremony, the building of a royal palace, the payment of my employees that is maids/housekeepers, chefs/cooks, security/guards/bodyguards, etc.) (Those employees would be chinese) & the support of China in securing full membership at the United Nations as a sovereign nation

They would also have access to the land to construct luxury resorts/hotels, apartments, casinos, commercial estates, etc.. of course, I would take 10 percent shares of those investments & assets as the land & sea area would be provided by me

The chinese would also have full rights to use land reclamation projects to expand the land for construction.

My new country would also only use the chinese yuan as the only legal tender
