Also, there has been no change in the taxes associated with exporting oil. Not that it would be a concern anyways.
Money talks, BS walks : the chicoms are all over the world, even off shore from cuba, scouring for every possible source of oil. You've done our homework but it's with past data/thinking. Whyever, in the Book of Revelation, do 200 million chinese invade the middle east/israel? OIL! They're still lusting after OIL ENERGY to feed their ever-growing habit. It's just like our federal government's cocaine habit of fuel taxes(and quashing any promising new energy answer), the chicoms, us, everyone in the world has an oil cocaine habit....and steadily declining supplies. The coming end is clear.
