Japanese silk

[1] Silk from East Asia had declined in importance after silkworms were smuggled from China to the Byzantine Empire.

[2] This led to a demand for silk from China and Japan, where as late as the nineteenth and early twentieth centuries, Japanese exports competed directly with Chinese in the international market in such low value-added, labor-intensive products as raw silk.

This increase in exports was mostly due to the economic reforms during the Meiji period and the decline of the Qing dynasty in China, which led to rapid industrialization of Japan whilst the Chinese industries stagnated.

[3] During World War II, embargoes against Japan had led to adoption of synthetic materials such as Nylon,[4] which led to the decline of the Japanese silk industry and its position as the lead silk exporter of the world.

Today, China exports the largest volume of raw silk in the world.
