China is the biggest importer of crude oil in the world (3 million barrels) I’m not sure if it’s daily weekly monthly or yearly though.Just to be clear, though, oil prices are not collapsing because of COVID-19. At least not for the most part. They are crashing because of the breakdown of the agreement between Saudi Arabia and Russia and the resultant trade war that has ensued. Saudi Arabia is deliberately taking prices extremely low in order to pull customers away from Russia.
I'm not saying that changes your point about the potential impact on the American economy. But I just don't want to add further fuel to the fire of panic over COVID-19 for something that is not really related.
