Article is really sad. None of the three reasons are that interesting IMO.
1) drone hard to come by for India... If only they build their own like China or us, one drone is nothing.
2) author thinks China is stupid for not knowing drone is there. Wut! Its not Afghanistan!
3) this drone is ancient technology. He even said not top Israeli tech when they imported it.. Back in 2005. That is literally 3 generations of drone tech. What can China possibly learn from it? Other than India still use 10 yr old tech.
