我们在此介绍东亚至意大利近乎全球的 VLBI (EATING VLBI) 项目。报告了该项目的启动方式以及韩国、日本和意大利研究人员利用 VLBI 观测研究致密源的国际合作进展情况。介绍并讨论了与不同阵列的同步相关的问题以及所涉及的望远镜的技术细节。相对较高的观测频率（22 和 43 GHz）以及意大利和东亚之间的长基线产生了高分辨率图像。我们提供示例图像来演示 EATING VLBI 阵列的典型性能。研究结果吸引了国际研究人员，合作也在不断扩大，现在包括中国和俄罗斯站。本文讨论了正在进行的新项目，并简要讨论了未来使用更多望远镜和更好频率覆盖范围的可能性。
We present here the East Asia to Italy Nearly Global VLBI (EATING VLBI) project. How this project started and the evolution of the international collaboration between Korean, Japanese, and Italian researchers to study compact sources with VLBI observations is reported. Problems related to the synchronization of the very different arrays and technical details of the telescopes involved are presented and discussed. The relatively high observation frequency (22 and 43 GHz) and the long baselines between Italy and East Asia produced high-resolution images. We present example images to demonstrate the typical performance of the EATING VLBI array. The results attracted international researchers and the collaboration is growing, now including Chinese and Russian stations. New in progress projects are discussed and future possibilities with a larger number of telescopes and a better frequency coverage are briefly discussed herein.
