What does it mean:....."Lacks knowhow or state of the arts technology:?.....

A new system (because this isn't just a weapon it is a system) will never be fully mature till it has been used in combat and all the bugs have been sorted out and the designer can examine how the user uses the system to determine what features they need and what features they don't actually want. It is like someone who has never made a business computer before making a computer for a business that has never used computers before. The maker can only guess at what the user will want, and the user has no idea what the computer could be made to do for them. What this official is saying is that the Russian AF is not sure what features it wants and so it wants a mature system that has been used operationally before so they can work out exactly what they want from domestically produced UAVs. The AF can test the Israeli UAVs and decide what is useful and what is just window dressing and then formulate concrete requirements for a Russian made UAV. Note the most widely used UAVs in Russia/the Soviet Union, were used by the Army, specifically the artillery divisions with their Pchelkas. The requirements for the airforce are rather different.

russia and china must cooperate to create the equivalent UAVs of USA and the Israeli UAVs

What could Russia get from China? What Russia needs is some more experience with UAVs, and improvements in certain technologies like long range cameras that can see long distances or just see the ground clearly from very high up. It also needs high speed datalink technology to relay data over long ranges. They can already build gliders and aircraft and autopilots and automatic landing systems. The problem has been that very big UAVs are enormously expensive and up until about 2008 the Russian Armed forces weren't interested in such things or weren't interested enough to actually spend money. Now the money is there so it is worth making bigger models. In 5 years time they will have more UAVs than they know what to do with as long as they actually look at what is available and give good feedback to those bothering to try to fill their needs.

This looks like a copy of the American UAV? All technology and weapons are copied or stolen from the USA.

China has nearly fielded ARMED uav's close to predator, i.e., CH-3 drone.Where is russia in that area?  Russia "CAN" learn a lot from china, it isstarting to fall behind already...1billion people and much more money willend up making a difference after decades of military neglect in russia...wake up from your arrogance!
