I prefer Pinyin to Wade-Giles..
Not just because I were raised learning Hanyu and Pinyin, but Wade-Giles sounds a bit weird in my tongue
I prefer Tributary Ying State.
Indonesia as Vassal of Chinese
Tributary State of Shilifoshi (Ancient, Srivijaya)
Tributary State of Yindunixiya / Tributary Yinni State / Indebted State of Yindunixiya / Indebted Yinni State (choose one)
It's a bit strange, though. We always knows ourself as Yin Ni Hua Ren, but it seems that in Mainland, Indonesia is more popular as Yindunixiya, not Yin ni..
Indonesia as vassal of Turkey (Ottoman)
Kingdom of Aceh/ Sultanate of Aceh
Maya as vassal of America
Federal Republic of Central America
Thai as vassal of Srivijaya
Kingdom of Tambralinga / Nakhon Si Thammarat Kingdom
Khmer as vassal of Srivijaya
Kingdom of Champa?
Let's make this a little more complicated, shall we?
Respawned Egypt as vassal of Ottoman
Egypt Eyalet (Eyalet-i Misir) / Khedivate of Egypt (choose one)
Italy as vassal of Respawned Egypt
Fatimid Sicily/Emirate of Sicily (choose one)
