In light of the recent pandemic of COVID-19 spreading in the world, there have been many Chinese papers with only English abstracts published in Chinese journals. Some western papers have cited the Chinese papers, but only based on the abstract as the author would say they do not understand the Chinese full text.
I am a graduate student in the medical field with a good grasp of Chinese and English. Can I translate without permission, or offer to translate, these papers and publish in an indexed English journal/source? If I make the offer, what is the appropriate etiquette and considerations?
