ABSTRACT
Danang city is known as the most attractive tourist city in Vietnam as well as in the world. Danang possesses rich and diverse natural resources, urban space facing the river, sea, alternating hilly areas creating an urban structure that is both the modern and the natural. In addition, Danang has won the Vietnam ICT Index award for 12 consecutive years because of its smart, modern, and effective digital technology system in linking and supporting tourism development with the neighboring localities. However, the outbreak of the Covid-19 pandemic had caused millions of deaths in the most countries worldwide since 2019. Leading to the economic activities, the trade in services, tourism, transportation, etc.. have all been seriously affected, even stopped working together for a long time. After that, the appearance of vaccines has partly controlled the epidemic situation. But people's living habits and views relating the tourism have changed significantly. Thus, the trend of 'green tourism country-slow tourism' is being strongly responded by tourists after the Covid-19 pandemic. This is explained that the tourists will travel in small groups, enjoy travel experiences close to nature, immerse themselves in the culture of indigenous people, and combine with local sports activities. Therefore, the authors propose a model of 'diffusion planning' to effectively solve the problems in 'Green tourism planning for Danang City after COVID-19, vision to 2050' to contribute to the orientation of sustainable tourism development in Danang city. © 2022 IEEE.
