In 1911, the Chilean government forced him to leave Tacna, so he moved to Lima and was appointed director of El Peruano.
To avoid attracting unwanted attention, his works were published under pseudonyms such as Joseph Marius, René Tupic and Ramón Román.

He represented Peru in missions to Mexico, Bolivia, Venezuela, France, Panama, Germany and Switzerland, additionally serving in the Peruvian delegation to the League of Nations.
