We study the Langevin dynamics of diffusive particles with regular pairwise interactions under mean-field scaling. 
By approximating empirical distributions with conditional distributions, we establish coercive and 
contractive properties for the modulated free energy functional. These properties yield near-optimal 
large-scale concentration and relaxation rates for the particle system throughout the subcritical regime. 
Furthermore, we derive generation of chaos estimates with the optimal order of particle approximation.
As a simpler instance, we demonstrate long-time convergence of the independent projection of Langevin dynamics.
