Diffractive interactions represent a lively domain of investigations, as confirmed by the progresses reported during the conference. We summarize the diffractive interactions session and put the new experimental data (Section 1), developments in modeling diffraction (Section 2) and the theoretical relations with Quantum Chromodynamics (Section 3) in perspective.
