This information was revealed by Deputy Chairman of the provincial People’s Committee Tran Tien Dung.
The province had not discussed the work contrary to rumours doing the rounds recently, he said.
Dung said if the province did plan to set up the Son Doong suspension cable, it would have to seek opinions from a number of related ministries and sectors and make a report on the impact on the environment.
In particular, the province would require permission and agreement from the UNESCO.
Following a conference on a working plan for this year held by the Quang Binh Department of Tourism on Monday, there were reports that the province had approved a plan to build a suspension cable to Son Doong Cave.
Several accounts on social network said the province had even chosen investors and companies to execute the work.
Many people raised objections as they worried that the building would damage the beauty of the famous wonder of the world.
Leaders of the Quang Binh Department of Tourism denied these reports.
“During the conference, we discussed a plan to ease difficulties for the tourism sector and attract more tourists to the province. The conference did not mention the suspension cable,” Ho An Phong, Director of the Quang Binh Department of Tourism, said.
Vietnam’s Phong Nha-Ke Bang National Park, which boasts of having the world’s largest cave Son Doong, was recognised as a world heritage site for the second time by UNESCO in 2015. The park was first added to the World Heritage List in 2003.-VNA
