Together with Abdus Salam, Riccardo Giacconi, George Coyne, and Francis Everitt, they founded the International Center for Relativistic Astrophysics (ICRA) in 1985.

It has been focused on exchange of information and collaborations between Italian and Korean astrophysicists on new issues in the field of Relativistic Astrophysics.
The symposia cover topics in astrophysics and cosmology, such as gamma ray bursts and compact stars, high energy cosmic rays, dark energy and dark matter, general relativity, black holes, and new physics related to cosmology.
Almost 80 physicists and engineers in widely diversified fields relativistic gravitation, space research, SQUID technology, large scale cryogenics, clock technology, laser and radar science and other fields - came together in the kinds of free technical exchange so characteristic of William Fairbank, in whose honor the meeting was held.
The second meeting was held in Hong Kong and was devoted to relativistic gravitational experiments in space.
The 2nd Galileo - Xu Guangqi meeting took place in Hanbury Botanic Gardens (Ventimiglia, Italy) and Villa Ratti (Nice, France) in 2010.
