High-impact papers from China, Japan, India, and Korea.

This paper compares 'high-impact' papers from China, Japan, India and Korea in 2012, together with papers from these countries in Cell, Nature, and Science (CNS) from 2010 to 2012. China leads on 'highly cited' and 'hot' papers in 2012, while Japan has the highest number in CNS (653), followed by China (471), Korea (131) and India (83). Although China published more high-impact papers in 2012, papers published in CNS were at a relatively low level, which appears to show that while some of the research in China is at a relatively high level, this is not entirely reflected in the number of papers in these 'elite' journals.
