In 1900 Klodt took part in organising and designing of the Russian pavilion for the Paris World Fair, mostly in collaboration with Konstantin Korovin, who played the major part in the exposition (and was later awarded the Legion of Honour by the French government). In 1901 Klodt, now under the strong influence of impressionism, started to work as stage designer, for the leading theatres of St Petersburg and Moscow. With Korovin he created the stage design for the ballet "The Little Humpbacked Horse" by Cesare Pugni at the Bolshoi Theatre, in 1901. In 1903, working with set designs by Alexandre Benois, he decorated the scene of Richard Wagner's "Gotterdammerung" for Mariinsky Theatre.
