#1 it means China’s IPCs that they receive can only be used to buy Chinese units. Yea, Russia can’t enter China unless they’re at war with Japan.
#2 I’m not a 100% certain of. If UK isn’t at war with China, I don’t think they can enter those TTys. Otherwise yes they could.
#3 Yes, China gets the cash. I’m not sure about Kwangtung but I’d assume it’d go to UK pacific unless their capital has been captured, then China would get the dough. I’m sure someone else will chime in with a definitive answer for ya.
1 also because they use the US figher it is important to keep this 1 seperated from the rest. Us could fly in forces there or even land troops in china so you have to be carefull not to mix this unit with the other forces.
2 AFAIK there is no requirement for UK to be at war for china to move into those zones. Would be great if there was a requirement though.
3 kwangtung is originaly UK so if the UK-pac is still alive they get the cash, otherwise china gets it untill india is liberated.
Also important to know, if a chinese area is liberated that contains a factory the factory is removed from the board. So sometimes it can really be beneficial to send 2 transports on a suicide mission to take 1 of those chinese areas with a factory on it and not only capture the zone but also destroy a factory in the process.
