Today's announcement follows the successful launches on Twitter and Sina Weibo pages last month, each breaking growth records in their first month of operation. Manchester United also has over 34 million fans on its Facebook page, which launched in 2010.
Richard Arnold, group managing director, said: "Today marks another exciting development in the club's digital media offering. These social media sites provide us with the platform to unite our fans across the globe and bring them closer to the club.
"Manchester United has an extremely passionate and loyal fan base and we have been overwhelmed by the success of our Twitter and Sina Weibo pages; our Twitter page alone achieved 350k followers in its first 24 hours of operation.
"We look forward to building on this enhanced level of fan engagement with the new services we have launched today."
