Manchester United and Manchester City are to face each other in China this summer as part of the International Champions Cup (ICC), the clubs have announced.
The match will take place in the Bird's Nest stadium in Beijing on July 25 and will be one of City's first under Pep Guardiola, who is set to succeed Manuel Pellegrini at the start of that month.
The ICC tournament will also see United play Borussia Dortmund in Shanghai on July 22, and City take on the German side in Shenzhen on July 28.
Former United defender Nemanja Vidic said on MUTV: "I think it's great news we're coming on tour to China.
"We have so many followers in the country, over 100 million fans and it's good to visit them and spend some time with them. They're really passionate about United.
"I was in China in 2007 and I have to say the amount of energy we got from the fans there was unbelievable."
Former United midfielder Bryan Robson said: "They're great games to look forward to.
"Dortmund are just behind Bayern Munich as the biggest team in Germany and have some fabulous players.
"It'll be a treat for the fans to experience a derby game. People have said it'll be one of (Pep) Guardiola's first games as City manager but that doesn't matter as much as it's a derby and you have to go out there and try to win."
