To the Empire of Japan:
This is an ultimatum from the Empire of Russia. End hostilities now with the Empire of Korea, with a status quo ante bellum. Or prepare yourself to face the might of Russian Empire. By now our navy has been put on red alert (OOC: ) and the garrison of Vladivostok is being mobilized.
The attack on Korea was completely unprovoked and is just an attempt by the Empire of Japan to extend itself, to gain more colony, more power!
We ask the Emperor of Japan, to end this now, or prepare itself to face the consequences.
