This seems to be the opposite point you want.
Everybody is going to have increased expenses for everything due to their oil dependency _except_ China. Which will raise the price of Chinese exports to the market price but giving China a lot of producer surplus.
Or China can keep doing it's Belt & Road plans and grant other countries money to help with their oil problems in exchange for territory. Or also keep prices lower to continue hollowing out other countries manufacturing capabilities.
