Wu said the operations were conducted in accordance with international law, and were professional and safe.
Wu made clear that what the US media reported were not in accordance with the fact, which said that two Chinese J-10 fighter jets 'intercepted' a US P-3 spy plane.
Wu added that recently the US has conducted several operations of US navy ships and aircraft entering into China's maritime area and airspace, which encroached on China's sovereignty and could risk flaring up tensions in the maritime body.
