China could join the fight against the Islamic State terrorist group, aiding Russia in its anti-IS efforts, Sputnik News reports, quoting The Washington Times reports.

China is concerned about a growing number of “Chinese-origin” terrorists within IS group, which is banned in a range of countries, including Russia and the United States, the newspaper said on Wednesday.

“The real question is whose side will they be on,” a defense official was quoted as saying by The Washington Times, which suggested that Beijing will side with the Russian campaign against ISIS instead of joining forces with the US-led anti-IS coalition.
