BEIJING (Reuters) -China views the situation in Gaza as "very serious" with the risk of a large-scale ground conflict rising and the spread of armed conflicts along neighbouring borders, Chinese state media said on Monday, citing the country's Middle East special envoy. The envoy Zhai Jun, who is visiting the Middle East, said spillover effects in the region and internationally are widening, as conflict along the Israeli-Lebanese and Israeli-Syrian borders spread, "making the outlook worrisome". Zhai called on the international community to be "highly vigilant in this regard" and to take immediate action urging parties concerned to strictly abide by international humanitarian law and avoid a serious humanitarian disaster while putting in "joint efforts to control the situation".
