Under the agreement, Vietnamese and Omani citizens holding diplomatic, special and official passports valid for at least six months will be granted visa-free entry, stay, transit and exit within 90 days from the date of entry, according to the government portal.
The move contributes to boosting economic and tourism cooperation between both countries.
Vietnam has so far signed bilateral agreements to exempt visas for bearers of diplomatic and official passports from 88 countries and territories.
