In the past three years, it has provided comprehensive data on the international impact of Chinese academic journals. Using the clout index (CI) to rank the Chinese academic journals, "the Highest International Impact Academic Journals of China" and " the Excellent International Impact Academic Journals of China" are announced every year. By introducing the rating criteria of the "Annual Report for International Citation of Chinese Academic Journals", the characteristics of high impact journals are discussed. Especially, the status of the pharmaceutical journals is discussed. We found that there are increasing numbers of Chinese journals that are included in the SCI, and some of them are high impact journals. However, journals published in Chinese are still facing difficulties to be included in SCI, even though they show higher impact than journals published in other non-English languages. The Chinese Pharmaceutical journals need to enhance their international impact, but Journals on Chinese Medicine show high impact.展开更多
