Production of hadron exotics in high energy processes may play a role in unravelling their nature. In high energy limit, the leading power behavior of the cross section of exclusive processes is usually encoded in the constituent counting rule. In this talk I will demonstrate for the process involving hadrons with hidden flavors the constituent counting rule requests modifications. I will use effective field theory to derive the power scalings. After the e+e− → VP example I will discuss the production of hadron exotics including the X(3872) and Z±c in high energy process. I will also briefly talk about the challenge of the molecular interpretation of X(3872) based on its large production rates in hadron collisions.
