Alongside promotional activities and cooperation with South Korean partners, local authorities are working to attract visitors from a wider range of international markets.
Officials said the Korea Small and Medium Business Association (KOSTA), which represents around 20,000 companies, began cooperating with Do Son earlier this year and has established a representative office in the locality.
The partnership is expected to support tourism promotion, workforce training, product development and investment attraction.
Do Son is also refreshing its tourism products, combining traditional beach holidays with rural tourism and cultural experiences centred on its famous buffalo fighting festival.
Local authorities said businesses had proposed bringing thousands of international visitors to this year's festival, one of the area's best-known cultural attractions.
The city is also betting on upgraded tourism infrastructure, including the 480-hectare Dragon Ocean Do Son International Tourist Area, one of Vietnam's largest coastal reclamation projects.
The complex features a 27-hole golf course, a five-star resort, an artificial beach, a water park, a convention centre and other leisure facilities aimed at attracting higher-spending international visitors.
Improved transport links connecting Do Son with central Haiphong, Cat Bi International Airport, expressways and other northern coastal destinations are also expected to support tourism growth.
Experts say Do Son should further develop its night-time economy, entertainment complexes, cultural festivals and international events while building on its advantages as a gateway to northeast Asian markets.
They also urged the destination to reposition itself from a traditional seaside resort into a year-round coastal tourism and lifestyle hub capable of competing with leading regional destinations.
