What are some factors that influence the development of tourism in the host and supply country?

Several factors influence the development of tourism in both the host and supply countries. In the host country, natural attractions, cultural heritage, infrastructure quality, and political stability play crucial roles in attracting tourists. For the supply country, factors such as economic conditions, travel regulations, marketing strategies, and the availability of travel services can significantly impact tourism flows. Additionally, global trends, such as health and safety concerns or climate change, also shape tourism dynamics in both contexts.
