For cooking, light weight gas stoves are convenient, except of course when you run out of gas and that's it. Unlikely to be any supplies where you are going.
Consider MSR Dragonfly petrol trekking stove.
Sure, you have to carry fuel in safety bottles, but you are more likely to be able to buy fuel as you go.
Also, Dragonfly can use diesel as a backup fuel...
Before you go, test out how much fuel you use, say boiling a litre of water or cooking the sort of meal you might use out there.
Consider effects of altitude and ambilent temperature etc to estimate how long fuel might last.
Obviously, you cannot take petrol or gas when flying in to the region..!
Unleaded petrol may be difficult to get, but diesel should be available.
May need to negotiate to buy small quantities required.
If using diesel, may be worth buying field spares kit specific to the Dragonfly model if it contains spare needle jet which will become blocked much more quickly due to diesel burning dirty compared to petrol...
