|On January 30th, Japan and Great Britain signed a treaty of military alliance. The treaty provisions stated that if either country was attacked by another country, the co-signatory would maintain benevolent neutrality. If it was attacked by two or more countries, the co-signatory was committed to go to war on behalf of the ally. The agreement was aimed primarily at Russian expansion. The Japanese and the British felt threatened by the Russian seizure of Manchuria and Russia's claims to the Korean peninsula.
