Saudi oil fields provide 70% and 50% of the oil China and Japan uses.

Any disruption would cause economic chaos.

Libya wasn’t a “Saudi oil field” -— but yet Libya does have massive oil reserves, though not as massive as Saudi Arabia, Iran and Iraq.

Libya providing a significant chunk of oil to Western European countries is key (any disruption would cause economic chaos), as is what you listed concerning how much oil China and Japan obtains from Saudi Arabia.

Egypt is on the border of Israel, so that might figure in, though Egypt has a lack of oil reserves. Israel is the only tried-and true ally in the ME, so that obviously figures in as well.

So we are left with Sudan and Rwanda having no major oil fields, and they and Nigeria (though it has some oil fields) all being sub-Saharan.

No.

Saudi Arabia provides about 10% of the oil China uses.

Nearly all of Japan's oil is imported. Saudi supplies a 1/3 of that.
