> To keep a military base in a country you either need to be allowed to do so, or you have to do so by force, by occupying the country.

There are all sorts of levers US, China, Russia can pull to in order to put pressure on a country for such things. There's occupation, mutual benefits, long standing agreements post wars, soft power, sanctions, etc. Geopolitics is complicated.
