Nostradamus: The East will subjugate the West

This is a pearl from Nostradamus' 1559 Almanac:

"From the house seven through death in mortal succession,
Hail, tempest, pestilent evil, furies:
King of the East all the West in flight,
He will subjugate his former conquerors."

Who is the King of the East and who are his former conquerors?

I'd like to bring up this analysis made in the The Asian Times:

"In the middle of the 19th century, first Britain, then Britain allied with France, fought two wars with China. These are called the Anglo-Chinese Wars in China; in the West, they are more frequently called the Opium Wars."

"The Opium Wars were fought over the Western powers' demand that China allow free license for British and French companies, particularly the British East India Company, to import and sell opium in China."

"The Chinese government at the time well knew of opium's destructively addictive effects, but it was powerless to fight off the, by then, technologically superior Western powers. The Chinese defeat in the First Opium War in 1843 led to China ceding its control of, and British rule over, Hong Kong for 154 years; the 1860 Treaty of Tianjin that ended the Second Opium War was a virtual unconditional surrender by the Chinese: besides allowing the opium trade, it also allowed large Western military outposts (including those of the United States) to be set up in Beijing, as well as giving Western navies free access to navigate up the Yangtze River."

"For at least the next century, the humiliation and subjugation of the Opium Wars burned in the heart of all Chinese nationalists."

"One hundred and fifty years ago, the West subjugated China by addicting it to opium. Today, that power dynamic has been reversed. It is the West, especially the United States, that has become addicted, to an equally or even more addictive substance, cheap consumer products, and, more important, the profits that accrue from them."
