The Governments of Japan and Great Britain actuated solely by a desire to maintain the status quo and general peace in the Extreme East, being moreover specially interested in maintaining the independence and territorial integrity of the Empire of China and the Empire of Corea, and in securing equal opportunities in those countries for the commerce and industry of all nations hereby agree as follows:--


The High Contracting Parties having mutually recognized the independence of China and of Corea declare themselves to be entirely uninfluenced by any aggressive tendencies in either country. Having in view, however, their special interests; of which those of Great Britain relate principally to China, while Japan in addition to the interests which she possesses in China is interested in a peculiar degree, politically as well as commercially and industrially, in Corea, the High Contracting Parties recognize that it will be admissible for either of them to take such measures as may be indispensable in order to safeguard those interests, if threatened either by the aggressive action of any other Power or by disturbances arising in China or Corea and necessitating the intervention of either of the High Contracting Parties for the protection of the lives and property of its Subjects.


If either Japan or Great Britain, in the defence of their respective interests as above described, should become involved in war with another Power, the other High Contracting Party will maintain a strict neutrality and use its efforts to prevent other Powers from joining in hostilities against its Ally.


If in the above event any other Power or Powers should join in hostilities against that Ally, the other High Contracting Party will come to its assistance and will conduct the war in common and make peace in mutual agreement with it.


The High Contracting Parties agree that either of them will, without consulting the other, enter into separate arrangements with another Power to the prejudice of the interests above described.


Whenever, in the opinion of either Japan or Great Britain, the above mentioned interests are in jeopardy, the two Governments will communicate with one another fully and frankly.


The present Agreement shall come into effect immediately after the date of its signature and remain in force for five years from that date. In case neither of the High Contracting Parties should have notified twelve months before the expiration of the said five years the intention of terminating it, it shall remain binding until the expiration of one year from the day on which either of the High Contracting Parties shall have denounced it, but if when the date fixed for its expiration arrives either Ally is actually engaged in war the Alliance shall, ipso facto, continue until peace is concluded.

In faith whereof the undersigned duly authorized by their respective Governments have signed this Agreement, and have affixed thereto their seals.
