  Who is paying for the transit though? Russia or the buying country?
context: Geopolitics is so weird to me. They're at war but still let them transport their oil through their country. >
  
  There are multiple reasons:
  1) they use this oil too 
  2) some of the oil is heading to Europe and if you shut it down they aren’t that happy 
  3) they get some money for letting it flew through their country (transit tariff)
