Afterwards, he set out on a tour of the central and eastern European capitols, visiting Warsaw on December 3, Bucharest on December 8, Belgrade on December 12, and Prague on December 15, in each case discussing the European situation with the ministers of the countries in question, and seeking to foster friendly relations with France.On December 10, 1937, it was announced that a plot to assassinate him at Prague had been discovered by the French Police and the prospective assailant was arrested.
He was reappointed Foreign Minister in the reconstructed Chautemps government in the third week of January 1938 but was excluded from Leon Blum's cabinet in March 1938.During the Spanish Civil War, he worked alongside his British counterpart Anthony Eden in fleshing out the policy of nonintervention.
