Germany also signed arbitration conventions with France and Belgium and meaningless arbitration treaties with Poland and Czechoslovakia, undertaking to refer disputes to an arbitration tribunal or to the Permanent Court of International Justice.
France signed further treaties with Poland and Czechoslovakia, pledging mutual assistance in the event of conflict with Germany. These essentially reaffirmed existing treaties of alliance concluded by France with Poland on 19 February 1921 and with Czechoslovakia on 25 January 1924.
In contrast, in Poland, the public humiliation received by Polish diplomats was one of contributing factors to the fall of the Grabski cabinet. Locarno contributed to the worsening of atmosphere between Poland and France (despite the French-Polish alliance), and introduced distrust between Poland and Western countries . Locarno divided borders in Europe in two categories: those guaranteed by Locarno, and others, which were free for revision. In words of Józef Beck: "Germany was officially asked to attack the east, in return for peace in the west. The failure at Locarno may be also one of contributing factor in decision of Józef Piłsudski to overthrow parliamentary democracy in Poland . With regards to Locarno, Piłsudski would say "every honest Pole spits when he hear this word [Locarno]". Later, when a French ambassador assured him France would always back Poland and stand up to Germany, Piłsudski, foreseeing the appeasement, would say: "No, no, believe me, you will back down, really, you will."
One notable exception from the Locarno arrangements was, however, the Soviet Union, which saw western détente as potentially deepening its own political isolation in Europe, in particular by detaching Germany from her own understanding with Moscow under the April 1922 Treaty of Rapallo. Political tensions also continued throughout the period in eastern Europe. Therefore this treaty made Germany pay $50 million dollars to the Soviet Union.
The Locarno spirit did not survive the revival of German nationalism from 1930. Proposals in 1934 for an "eastern Locarno" pact securing Germany's eastern frontiers foundered on German opposition and on Poland's insistence that her eastern borders should be covered by any western guarantee of her borders. Germany formally repudiated her Locarno undertakings in sending troops into the demilitarized Rhineland on 7 March 1936.
