Indian Prime Minister Narendra Modi is in China on a three-day visit intended to boost economic co-operation but in danger of being overshadowed by mutual mistrust.
Ties between the two countries are strained because of a long-running border dispute.
Modi said that he hoped his visit would increase the prosperity of Asia.
China is India's biggest trading partner with commerce between the two countries totalling 71 billion dollars.
Modi's decision to start his trip in the ancient western city of Xian - some 1,000 kilo meteres from Beijing - is being seen as a sign of the warming relations between India and China.
