The economic strengths of these two countries are widely considered complementary - China is perceived to be strong in manufacturing and infrastructure while India is perceived to be strong in services and information technology. China is stronger in hardware while India is stronger in software. China is stronger in physical markets while India is stronger in financial markets. The countries also share certain historical interactions - the spread of Buddhism from India to China and trade on the Silk route are famous examples.
However, there are also geopolitical differences between China and India that some argue would make this term inappropriate. The effects of the Sino-Indian War of 1962 have meant that relations between the countries have been cautious and slow. While China is a temperate continental state India is confined within the Indian sub-continent and has a tropical climate. Culturally, China is connected to the developed East Asian nations of Japan and South Korea. Their political systems are also vastly different, with China being ruled by a single party and India being the world's most populous democracy. The commonly-cited complementary nature of China and India's economies is also being questioned as the service sector in China is rapidly growing and threatening to match or overtake India's within a decade, while India's manufacturing sector has seen tremendous growth in recent years.
