Just a peek into the SCRA-Coalition Lore: The Current Chinese/Russian Populations are from the sabotours and spies that slipped aboard the Sleeper Ships (Most seemed to go onto the Hispania, the next largest amount are from the Rheinland and Kusari, the Bretonia and Liberty had very low levels of infiltration. Our lore dictates that we helped fan the flames of the Von Roh rebellions (although we were too small in numbers and too spread out at the time to take real advantage of it to usurp any power.).
There are 'rumours' of another sleeper ship, however even I don't know if they were made Canon or not. *shrug* A large portion of our Population simply 'took up' Russian/Chinese names to 'carry on the spirit' of the Coalition, only a small population are true-blue Coalitioners. It's a sorta 'Culture Asssimilation' only with those who come in are 'absorbed' and take up the culture of those who came before as taught by those left over. *shrug*
