  Studies of exotic hadrons such as the $\chi_{cl}(3872)$ state provide crucial
insights into the fundamental force governing the strong interaction dynamics,
with an emerging new frontier to investigate their production in high energy
nuclear collisions where a partonic medium is present. This contribution
discusses the production mechanisms of exotic hadrons in such collisions and
analyzes novel effects from the partonic medium, demonstrating the potential to
use heavy ion measurements for deciphering their internal structure and
understanding their in-medium evolutions.
