Title:Dynamics of young starburst clusters in the Galactic centre and the spiral arms

Abstract:
In the past few years, high-angular resolution observations have revolutionised our knowledge of the 
dynamical properties of starburst clusters in our Galaxy. In this contribution, I will summarise the first 
results of the cluster proper motion campaign, which lead to the derivation of the orbital motion of the 
Arches and Quintuplet clusters around the Galactic centre, and allowed us to derive the internal velocity 
dispersion of resolved starburst clusters for the first time.
