The Revival of the Silk Road increased foreign trade.

Explanation:

The Tang dynasty prospered because of its open trade with the neighboring countries, both by sea and overland along the Silk Road, a route that was originally formed during the Han dynasty. The Tang dynasty reopened the Silk Road in 639 after securing the stability and safety of the route through conquest of hostile neighboring states along the route. During this time long-distance trade did not just transport goods and luxuries; it was also a lifeline of ideas and innovation from Persia, India, and the countries of the Middle East and Central Asia. These innovations changed the ways of fashion, gave Chinese artists new forms of ceramics, and allowed them to learn stronger ways to craft silver, to give just a few examples.
