I am not professionally involved in these fields but I have read that among those who are there is a very jaundiced opinion of Chinese and Indian scientific research. If none of the following hold completely ignoring their publications is apparently a good heuristic; at least one foreign co-author or one who did their doctorate in the first world or an institution or author with a significant reputation. Living in China and having some minimal experience with the Chinese attitude to plagiarism/copying/research makes this seem plausible. I doubt anyone's missing anything by ignoring scientific articles published in Mandarin. I make no such claims for social sciences.
