[China Warlord] At war against allies and axes... Goodbye Archivement?

Hey everyone,

it's my first iron man attempt as a chinese warlord. I could beat japan. But then...

- the communist joined the allies

- Yunnan joined the axes

So to get the archivement, I have to claim both territory in a peace conference right? I won't get the archivement by just occupying the territory during war.

​

Thanks and RIp^^
