Early Chinese histories refer to visits to eastern islands that some historians identify with Taiwan. Troops of the Three Kingdoms state of Eastern Wu are recorded visiting an island known as Yizhou in the spring of 230.

The Book of Sui relates that Emperor Yang of the Sui dynasty sent three expeditions to a place called "Liuqiu" early in the 7th century. They brought back captives, cloth, and armour. The Liuqiu described by the Book of Sui had pigs and chicken but no cows, sheep, donkeys, or horses. It produced little iron, had no writing system, taxation, or penal code, and was ruled by a king with four or five commanders. The natives used stone blades and practiced slash-and-burn agriculture to grow rice, millet, sorghum, and beans. Later the name Liuqiu (whose characters are read in Japanese as "Ryukyu") referred to the island chain to the northeast of Taiwan, but some scholars believe it may have referred to Taiwan in the Sui period.
