Among his books in French, the most important would be the three-volume Roseraie de l’Arménie (Rose Garden of Armenia), dedicated to Armenian medieval poetry, a subject of which he was a respected translator and scholar.
Between 1898 and 1911, he published the literary journal Anahid, which would become an influential name in Armenian literature. He also wrote for many Armenian newspapers throughout the world.
Tchobanian adopted ideological positions closer to the Reorganized Hunchakian Party, created after the division of the Hunchakian Party in 1896. Later, he entered the ranks of the Liberal Party, created after 1908 in Europe by members of the Reorganized Hunchakian Party.

In October 1921 Tchobanian entered the Democratic Liberal (Ramgavar Azadagan) Party, founded in Constantinople, and was elected first chairman of its Central Board. During the 1920s, along with the party, he adopted a position favorable to cooperation with Soviet Armenia to further its economic and social development, including the settlement of Armenian refugees and orphans. He visited year the United States from coast to coast in 1926-1927. In 1929 he relaunched Anahid, which would last until 1949, with a pause between 1940 and 1946 due to World War II.
