The two High Contracting Parties, basing their action on the essential principles contained in the Treaty of December 17, 1925, and in the Protocol of relations between them, being firmly convinced that the only reliable guarantee of permanent peace is the effective reduction of all kinds of existing armaments and manifesting their inflexible desire to pursue in the future also their efforts to bring about a universal reduction of armaments, have considered it desirable, in order to give a fresh proof of the mutual confidence so happily established between the two countries, to supplement Article II of the Protocol of December 17, 1929 by the following reciprocal undertaking:
Neither of the High Contracting Parties shall proceed to lay down any naval fighting unit whatsoever for the purpose of strengthening its fleet in the black Sea or in neighboring seas, or to place orders for any such unit in foreign shipyards, or to take any other measure the effect of which would be to increase the present strength of its war fleet in the above-mentioned seas, without having notified the second contracting Party six months previously.
The present Supplementary Protocol shall be ratified and shall become from this moment an integral part of the protocol of December 17, 1929.
PROTOCOL OF SIGNATURE
In proceeding to sign the Protocol of today’s date between the Turkish Republic and the U.S.S.R. concerning naval armaments, the two Contracting Parties are agreed that the expression “the present strength of its war fleet” contained in the said protocol shall be deemed to include vessels of war which have been laid down, or for which orders have been placed, by the two Contracting Parties for the Black Sea or neighboring seas up to the moment of the conclusion of this protocol.
