China and India are in the market. Course, there's not many people there.
People don't need oil - cars do.
If the UAE (or any Arab country) sells oil to China or India, that will free up that same exact amount that China and India is already buying somewhere else this very minute, perhaps from Indonesia, or Russia.
Oil is a worldwide commodity. Each drop that is taken out of the ground in essence goes into a worldwide market. If we can't buy it from country X, we can buy it from country Y, AND THEY KNOW IT.
