Chinese Premier Li Keqiang called on Saturday for greater global cooperation against terrorism, state media said, as the Asian giant seeks greater international support for its anti-terror fight. Speaking at an Asia-Europe summit, Li said various security challenges - conventional and unconventional - remain prominent even though those regions had remained generally stable and peaceful. "Acts of terrorism are common challenges faced by every nation. Countries should work more closely to fight terrorism, and build societies that are truly open and tolerant so to root out the soil where it grows," said Li. China has sought Western support for its own "war on terror" since the attacks in Paris last November.
