Which regions were part of the Tang-Song tribute networks?

• A. Korea (Goryeo); Vietnam (Dai Viet); Tibet, among others.
• B. Only Korea.
• C. Only Vietnam and Korea.
• D. Japan and Siam.

Answer: (A)

The main idea being tested is how the Tang–Song rulers built a network of diplomacy through the tribute system, where neighboring states acknowledged the Chinese emperor and in return gained legitimacy, access to trade, and gifts. Korea, represented by Goryeo, regularly sent missions to both Tang and Song courts as part of this system, showing that it stood within the Chinese-era diplomatic framework. Vietnam, under Dai Viet, also participated, sending tributary delegations and receiving recognition and exchange from the Chinese court. Tibet was a major frontier region that engaged in the same kind of recognized relationship with China, fitting neatly into the tribute network. The phrase “among others” signals that many other polities participated as well, not just these three.

Choices that limit participation to only one region or that pair regions not associated with the traditional tribute framework don’t capture the broader network established by Tang and Song diplomacy, which is why this broader listing is the best answer.
