I could see some wars between them. I could see conflict over control of Singapore being a major issue, as well as other Islands in Austronesia. I can see various Islands trading hands between the Han and Malagasy Enterprises through their history. Singapore may have come into Han possession as a result of their most recent war, which really amps up their animosity.

Works for me. Perhaps a few islands that were once owned by one of them gained independence during the Great War and need to be "reminded" of their loyalties? ...Only both nations have different ideas as to who owns that loyalty?

[@Willy Vereb] Also works for me.
