Unfortunately, due to the COVID-19 pandemic situation in Italy, the 34rd International Conference on Advanced Information Networking and Applications (AINA), including the International Workshop on Recent Advances for Multi-Clouds and Mobile Edge Computing (M²EC 2020), which were to be held in Caserta, Italy, had to be cancelled. Therefore, the proceedings of the conference are available online from the conference website at http://voyager.ce.fit.ac.jp/conf/aina/2020/.
