India and China are two large, neighboring countries with long histories and predominantly rural populations. Both countries have seen significant economic growth in recent decades. India's GDP was $4 trillion in the last reported quarter while China's GDP was $10 trillion. Currently, China has the world's largest population at over 1.3 billion people, while India is second largest with over 1.15 billion people. In the past, India and China had periods of both positive and strained relations, but relations have improved in recent decades through increased high-level visits and agreements between the countries' leaders. Both countries now see each other as important economic and geopolitical counterparts.
