@Tolstobrov Anatoliy this test should be invalid "Naturally, neither empire will join the alliance its rival is currently in", however it test that one empire is trying to claim a country owned by its rival.

Note that "the territories they have once acquired remain parts of the empire FOREVER". This is written less clearly in Russian statement. Then you will pass 10-th test. Good luck!
