AND
SUPPLEMENTARY AGREEMENT
Signed at Washington, February 6, 1922
I
The High Contracting Parties agree as between themselves to respect their rights in relation to their insular possessions and insular dominions in the region of the Pacific Ocean.
If there should develop between any of the High Contracting Parties a controversy arising out of any Pacific question and involving their said rights which is not satisfactorily settled by diplomacy and is likely to affect the harmonious accord now happily subsisting
between them, they shall invite the other High Contracting Parties to a joint conference to which the whole subject will be referred for consideration and adjustment.
II
If the said rights are threatened by the aggressive action of any other Power, the High Contracting Parties shall communicate with one another fully and frankly in order to arrive at an understanding as to the most efficient measures to be taken, jointly or separately, to meet the exigencies of the particular situation.
III
This Treaty shall remain in force for ten years from the time it shall take effect, and after the expiration of said period it shall continue to be in force subject to the right of any of the High Contracting Parties to terminate it upon twelve months' notice.
IV
This Treaty shall be ratified as soon as possible in accordance with the constitutional methods of the High Contracting Parties and shall take effect on the deposit of ratifications, which shall take place at Washington, and thereupon the agreement between Great Britain and Japan, which was concluded at London on July 13, 1911, shall terminate. The Government of the United States will transmit to all the Signatory Powers a certified copy of the proces-verbal of the deposit of ratifications.
The present Treaty, in French and in English, shall remain deposit in the archives of the Government of the United States, and duly certified copies thereof will be transmitted by that Government to each of the Signatory Powers.
