China, Iran, North Korea and Russia will face the U.S and the armies of Europe in the final World War, one side will conquer the other side, and one nation from the victorious side will conquer the remaining nations who it fought alongside.
The ruler of these nations will be the Antichrist and will reign for 1000 years until Christ comes again to banish him and his followers to the depths of hell for all eternity.
Revelation 16:12 says: The sixth angel poured out his bowl on the great river Euphrates, and its water was dried up to prepare the way for the kings from the East. This is the only time that China may be mentioned in the Bible that I know of.
This coupled with Revelation 9:14-16 appears to say 200 million troops will come from the east. Revelation 9:14-16 says: which says: It said to the sixth angel who had the trumpet, “Release the four angels who are bound at the great river Euphrates.” And the four angels who had been kept ready for this very hour and day and month and year were released to kill a third of mankind. The number of the mounted troops was twice ten thousand times ten thousand. I heard their number.
