Also, does this make Primorye a Second World country or a Third World country with the current GDP per capita?
I don't know what would the "Dollar" of the Ivangorod world. The Krona, perhaps? I think it would be Second World.
Kyuzo, there is one correction that I have to point out: Primorye's territory consists of: all of the OTL Spanish East Indies, the entire Papuan Island and it does not include the rest of OTL Indonesia. Other than that, the languages are as follows: Sugbuyan, Bikolan, Ilokan, Tagalog, Waray-Waray, Sulugan, Tausugan, and the currency is the Primorian Rupak. Self-government is in 1945, and full independence is in 1991. Filipino as a term does not exist.
