Fast food chain Burger King is planning to open six more restaurants in Beijing by June next year, as part of a major expansion in China.

The company, which has 25 outlets in the country, officially opened its first restaurant in downtown Beijing this week in Joy City in the Xidan area.

John Chidsey, chairman and chief executive of Burger King Holdings (BKC), who was in Beijing for the opening of what was the company's 12,000th restaurant worldwide, said the group was aiming for fast growth.
