The Korea Astronomy and Space Science Institute is pleased to host the 6th East Asia VLBI workshop 2013. It will be held in Jeju Island, the biggest and most beautiful island in Korea. Compared with western countries, there have been quite active VLBI (Very Long Baseline Interferometry) activities in East Asia for the last couple of years. A combined network of the newly operating KVN (Korean VLBI Network) and the Japanese VERA (VLBI Exploration of Radio Astrometry) started to produce its scientific results. China has set up an ambitious plan to launch two radio antennas for space VLBI. Taiwan has started to set up the ALMA prototype antenna in the Greenland. The aim of this workshop is to bring astronomers and engineers in East Asia together and provides a place to present their scientific and engineering works. It will also serve a good opportunity to enhance regional collaborations through the East Asian VLBI Consortium.
