According to Amartya Sen
The transfer of ideas and skills in mathematics and science remains central to the contemporary commercial world whether for the development of information technology or of modern industrial methods. What may perhaps be less clear is how nations learn from one another both in enlarging the scope of public communication and in improving public health care. As it happens, both were important in the intellectual relations between China and India in the first millennium and remain central even today.
