Chung Kuo, book 6 : White moon, red dragon
David Wingrove1994

Once an unchanging world ruled by the Seven Emperors, Chung Kuo is now in turmoil. Its enemies marshal their armies - human and superhuman - against the last emperor, Li Yuan, and the rigid Chinese-ruled world of the 23rd century comes to its armageddon, the last battle which will shape its future.
