Benefiting from a series of preferential mechanisms, the tourism sector in Quang Nam province has truly recovered following the COVID-19 pandemic. Revenue in 2023 was estimated at around 326 million USD, or double the 2022 figure. The World Cultural Heritage destination of My Son Sanctuary was one of the first in Quang Nam to implement links. Technology applications support sightseeing by visitors, such as online ticket sales, QR code ticket checking, and payments via QR code and visa cards. This is a foundation for My Son Sanctuary to become a link within an eco-tourism, cultural tourism, and coastal tourism chain. Thanks to tight coordination, My Son welcomed over 360,000 visitors last year, including over 315,000 international visitors, an increase of over three-fold compared to 2022. Connecting cultural, ecological, and coastal elements is crucial for Quang Nam’s tourism development, as the local tourism sector moves towards diversifying green tourism products. Cooperative efforts between businesses and destinations are essential for attracting tourists and achieving positive outcomes.  In addition to two World Cultural Heritage sites and an extensive coastal area, Quang Nam holds vast untapped potential in the Cham Islands and Tam Hai - Ly Son archipelago. The province boasts numerous eco-tourism spots, traditional craft villages, and community-based tourism spots. These resources are being integrated into a unique Green Tourism product chain to ensure diverse offerings./.
