abstract = "In this work, we employed high angular resolution very-long-baseline interferometry (VLBI) observations in order to study the physical conditions in the jet regions near the central engine for the blazar 3C 454.3. We present preliminary results of the jet kinematics from multi-epoch observations at 43 and 86 GHz (with the VLBA and GMVA, respectively) during the period 2013–2017. We trace a new VLBI component (N) that emerged in Spring 2014. The component shows an untypical behaviour in its velocity pattern with a transition from fast to slow motion. Additionally, the radio flux density light curves at 86 and 229 GHz indicate variability, which is likely related to the appearance and propagation of the new feature in the jet. Polarimetric images at 43 GHz (VLBA) and 86 GHz (GMVA) reveal the polarized sub-structure on sub-pc scales, which can be used to trace the local magnetic field topology and rotation measure.",
