A government scholarship allowed her to study at the Central Music School of the Moscow Conservatory with Stefan Kalianov and Mstislav Rostropovich.
In 1981 Xenia Jankovic gained proper international acclaim when she became first prize winner at the prestigious Gaspar Cassado[3] competition in Florence (Italy).
The Times (London) magazine described Xenia Jankovic's performance of Variations on a Rococo Theme (Tchaikovsky) as "She shoved to be one with the music".
Over the last decade she has made a number of recordings including Bach ́s Cello Suites, integral works for cello and piano by Beethoven (played on the period instruments), sonatas and pieces by Brahms, Chopin, Frank, Dvorak, Tchaikovsky, Debussy and Jevtic and concertos by Haydn, Dvorak, Elgar, Prokofiev, Khachaturian and Shostakovich.
Some of her disciples were Susanne Beer, Bridget Mac Rae, Sebastian Jolles, Vanda Djanic, Ulf Shade, Dirk Wietheger and Gernot Nutzenberger.
