The conference was held as part of the Vietnam International Travel Mart (VITM) Hanoi 2023.
It saw the attendance of representatives of the Vietnam National Administration of Tourism (VNAT), tourism management units at central and local levels, and travel companies.
VNAT General Director Nguyen Trung Khanh said this was a good opportunity for the provinces to introduce what they have to offer visitors in the peak time of domestic tourism this summer.
Leveraging the potential and unique identity of each locality in the overall linkage, the provinces have focused on building and effectively exploiting a series of new and attractive products such as a tour through ancient Vietnamese capitals, and a journey to discover heritages in the central region, Khanh noted.
They have even reached out to the international market by connecting with Laos and Thailand, he added.
The number of tourists to these provinces skyrocketed last year, reflecting the prospects brought about by regional tourism linkages, said the official.
On this occasion, the four provinces arranged booths to display publications and documents about their tourism potential and tourist destinations, as well as souvenirs and specialties.
Located in the southern reaches of the Red River Delta, Ninh Binh is known for its wondrous natural scenery, with a labyrinth of waterways, mountains, and plains as well as cross-cultural influences from the north to the south and from the mountains to the plains and coastal areas.
The province's Trang An Landscape Complex was recognised by UNESCO as a World Cultural and Natural Heritage Site in June 2014, becoming the first mixed natural and cultural property in Vietnam.
