Former world champions Russia were eliminated from the competition after their defeat.
China, who have only lost to Italy in the second round, won 25-22, 21-25, 25-23, 25-15.
"I think today's game was very hard, very difficult, especially the first three sets," said the Chinese team coach, Jenny Lang Ping.
"Russia is traditionally a very strong team above the net so it was very important for us to keep a good level ready for the next round."
Serbia suffered a second consecutive defeat as The Netherlands won 3-0 against them.
