The third in line to Britain's throne will be in India's neighbourhood on the invitation of the Chinese government, the BBC reported.
The invitation from China follows the official visit to Britain by the Chinese Premier Li Keqiang in June, when he met Queen Elizabeth II at Windsor Castle.
A formal royal announcement is expected soon, including information if the Duke of Cambrdige's wife Kate Middleton will be joining William, 32, for his trip.
Prince William's tour of China to improve diplomatic relations between Britain and the world's second-largest economy will be the most high-profile royal visit since the Queen and the Duke of Edinburgh toured the country in 1986.
Diplomatic relations between Britain and China have been repeatedly tested in recent years because of visits to London by the Dalai Lama, the spiritual leader of Tibet who is living in exile in India.
The Dalai Lama has met both Prime Minister David Cameron and Prince William's father Prince Charles, which would have upset Communist Party leaders in Beijing.
