The Red Devils claim to have an estimated 26.5 million supporters in the Asian country, 10 per cent of the overall population, with a new debit card launching for customers
Manchester United have agreed a fiver-year partnership with the Bank for Investment and Development of Vietnam (BIDV), the club has announced.
The agreement becomes United's first financial services deal in Vietnam, and BIDV can boast an annual turnover of $200 million (£131m) while the Premier League champions' estimated 26.5m supporters in the country now have the chance to get the bank's first ever affinity credit card.
The Manchester United credit card gives supporters chances to win giveaways, club discounts and prize draws, and club commercial director Richard Arnold said the amount of supporters living in Vietnam was a main reason for the partnership.
"Vietnam is a very important country for Manchester United," Arnold told the club's official website. "The club is lucky enough to have a large and very passionate set of fans there, with some 30 million supporters watching the team on TV last season.
"Some 10 per cent of the country's total Facebook users are also a Manchester United Facebook follower and the club has a database of over 2.4 million Vietnamese fans who have registered their interest in United. We are very pleased to be able to work with BIDV to offer them this great new product, a first for both the banks and Club in Vietnam.
"With more than 120 branches and 600 transaction offices as well as over 1300 ATMs in 63 cities, BIDV has the right amount of presence around the country to be able to connect with our fans.
"We know from the other financial services sponsorships we have around the world that fans find this a great way to engage with the Club, with deals putting hundreds of thousands of cards in the hands of United fans within weeks of being available.
"BIDV shares many of the same values of Manchester United, such as striving to be pioneers in its industry whilst respecting its history and traditions. Everyone at the Club is looking forward to a successful partnership."
