The international VLBI collaboration in East Asia is rapidly growing. Besides the successful integration of KVN and VERA (KaVA), now the network is expanding into China. This forms the East Asian VLBI Network (EAVN) and stimulates the activities of joint science promotion among researchers in this area. One of the primary science goals of KaVA/EAVN is to understand the physics of accretion and ejection in active galactic nuclei (AGN) and associated high-energy phenomena. The capability of quasi-full-year operation of KaVA/EAVN is suitable for monitoring the detailed structural evolution of relativistic jets. This allows us to address some major questions about jets such as the acceleration mechanisms, connection to gamma-ray flares and magnetic-field properties. Some of key AGN programs are project-led and promoted by the EAVN AGN Science Working Group. This includes a massive monitoring program of SgrA and M87 near in time to the Event Horizon Telescope observations, EAVN+Italy global VLBI (“EATING” VLBI) observations of powerful jets, as well as monitoring of other individual sources. Here we overview the ongoing expansion of EAVN and related AGN observing programs.
