  We report the suppression of Type-I Edge Localized Modes (ELMs) in the EAST
tokamak under ITER baseline conditions using $n = 4$ Resonant Magnetic
Perturbations (RMPs), while maintaining energy confinement. Achieving RMP-ELM
suppression requires a normalized plasma beta ($\beta_N$) exceeding 1.8 in a
target plasma with $q_{95}\approx 3.1$ and tungsten divertors. Quasi-linear
modeling shows high plasma beta enhances RMP-driven neoclassical toroidal
viscosity torque, reducing field penetration thresholds. These findings
demonstrate the feasibility and efficiency of high $n$ RMPs for ELM suppression
in ITER.
