The relationship between India and China is very sensitive. G20 will provide a platform for Xi and Modi to discuss about current issues. Contradiction between China and India is prominent. India worried about the cooperation between China and Pakistan, which is threatening the Kashmir controversy in India and Pakistan. China is concerned about military increasing cooperation between India and America. But China and India still have lots of common purposes in G20 in coping with structural reform, climate change, and anti-terrorism. G20 is still a great opportunity for two countries to discuss discrepancies.
