We introduce the Korean VLBI Network (KVN), a unique VLBI facility in Korea which allows simultaneous observations at 22, 43, 86 and 129 GHz with resolutions up to a milliarc-second. With the recent addition of VERA antennas at 22 and 43 GHz, the sensitivity and resolution of the array has been proven to improve to levels comparable to existing VLBI arrays. We also discuss the KVN AGN monitoring program, iMOGABA which, together with its twin single-dish program MOGABA, is monitoring the flux density of gamma-ray bright AGNs. A wide range of Key Science programs (KSP), including but not limited to the investigation of the origin of gamma ray flares on AGNs, will largely benefit from these monitoring.
