His Majesty the King of the United Kingdom of Great Britain and Ireland and of the British Dominions beyond the Seas, Emperor of India, and His Majesty the Emperor of All the Russias, animated by the sincere desire to settle by mutual agreement different questions concerning the interests of their States on the Continent of Asia, have determined to conclude Agreements destined to prevent all cause of misunderstanding between Great Britain and Russia in regard to the questions referred to, and have nominated for this purpose their respective Plenipotentiaries, to wit:  

His Majesty the King of the United Kingdom of Great Britain and Ireland and of the British Dominions beyond the Seas, Emperor of India, the Right Honorable Sir Arthur Nicolson, His Majesty's Ambassador Extraordinary and Plenipotentiary to His Majesty the Emperor of All the Russias;  

His Majesty the Emperor of All the Russias, the Master of his Court Alexander Iswolsky, Minister for Foreign Affairs;  

Who, having communicated to each other their full powers, found in good and due form, have agreed on the following.  
 

Arrangement Concerning Thibet  

The Governments of Great Britain and Russia recognizing the suzerain rights of China in Thibet, and considering the fact that Great Britain, by reason of her geographical position, has a special interest in the maintenance of the status quo in the external relations of Thibet, have made the following arrangement.  

Article I. The two High Contracting Parties engage to respect the territorial integrity of Thibet and to abstain from all interference in the internal administration.  

Article II. In conformity with the admitted principle of the suzerainty of China over Thibet, Great Britain and Russia engage not to enter into negotiations with Thibet except through the intermediary of the Chinese Government. This engagement does not exclude the direct relations between British Commercial Agents and the Thibetan authorities provided for in Article V of the Convention between Great Britain and Thibet of the 7th September 1904, and confirmed by the Convention between Great Britain and China of the 27th April 1906; nor does it modify the engagements entered into by Great Britain and China in Article I of the said Convention of 1906.  

It is dearly understood that Buddhists, subjects of Great Britain or of Russia, may enter into direct relations on strictly religious matters with the Dalai Lama and the other representatives of Buddhism in Thibet; the Governments of Great Britain and Russia engage, as far as they are concerned, not to allow those relations to infringe the stipulations of the present arrangement.  

Article III. The British and Russian Governments respectively engage not to send Representatives to Lhassa.  

Article IV. The two High Contracting Parties engage neither to seek nor to obtain, whether for themselves or their subjects, any Concessions for railways, roads, telegraphs, and mines, or other rights in Thibet.  

Article V. The two Governments agree that no part of the revenues of Thibet, whether in kind or in cash, shall be pledged or assigned to Great Britain or Russia or to any of their subjects.  
 

Annex to the Arrangement Between  

Great Britain and Russia Concerning Thibet  

Great Britain reaffirms the declaration, signed by His Excellency the Viceroy and Governor-General of India and appended to the ratification of the Convention of the 7th September 1904, to the effect that the occupation of the Chumbi Valley by British forces shall cease after the payment of three annual installments of the indemnity of 25,00,000 rupees, provided that the trade marts mentioned in Article H of that Convention have been effectively opened for three years, and that in the meantime the Thibetan authorities have faithfully complied in all respects with the terms of the said Convention of 1904. It is clearly understood that if the occupation of the Chumbi Valley by the British forces has, for any reason, not been terminated at the time anticipated in the above Declaration, the British and Russian Governments will enter upon a friendly exchange of views on this subject.  

The present Convention shall be ratified, and the ratifications exchanged at St. Petersburgh as soon as possible.  

In witness whereof the respective Plenipotentiaries have signed the present Convention and affixed thereto their seals.  

Done in duplicate at St. Petersburgh, the 18th (31st) of August, 1907.
