Chinese defense companies copy the US

The Chinese military establishment has long copied military hardware from other parts of the world, including the U.S. Some Chinese military drones have been seen at China's Zhuhai air show in model form.

China Aerospace Science and Technology Corporation built the CH-4 and it’s clear that the U.S. Reaper drone heavily influenced its design. The CH-4 has a claimed endurance of 30 hours and can travel nearly 2,000 miles at altitudes of up to 5 miles.
Another drone on display is built by Chengdu Aircraft Design is called the Wing Loong, and it also resembles the Reaper according to reports.

Of all the military drones on display at the air show, however, Defense News reports that the Wing Loong garnered the most attention. That drone reportedly has export deals in the works and the static display at the show features four hard points for weapons (laser-guided bombs, air-to-ground missiles, etc).

Another weapon on display, the Bateleur, was said to be a copy of the Bell-Boeing V-22 Osprey and is capable of vertical takeoff and landing. However, simply copying the V-22 Osprey would be a difficult endeavor, as that highly complex aircraft has been plagued with numerous problems during its lifetime.
This isn’t the first time that mimicry has struck Chinese aircraft design. China’s J-20 stealth fighter looks suspiciously similar to Northrop-Grumman and Lockheed Martin stealth fighter designs.

Two completely unrelated statements. Good job.

Agreed, even if these two paragraphs are separated by a blank line.
Maybe you'd be okay with it if he had used bullets.

The point of the article is american self-reinforcing chest-thumping and patriotism, in difficult economic times where the nation's impression of itself as a world-leading empire is wavering.

...That tools that perform the same functions tend to look similar or identical is not something that the author - or most commenters - want to dwell on. Better to simply assume without any actual evidence that the designs for these aircraft were ripped-off wholesale.

all drones look like US drones, because they all fly through the same air and thus are subject to the same laws of aerodynamics. thus a boeing looks like an airbus, which looks like a mcdonnell douglas, which looks like a tupolev, which looks like a caravelle, which looks like a... you get my point.

That's only true at high mach numbers, where aerodynamic forces dominate. At the slow speeds these drones travel, you can make practically anything fly.

There are some aspects which will be similar (e.g. glider-like wing aspect ratio for maximization of endurance). But the choice of a bulbous payload dome in front, butterfly tail, and pusher prop are all optional design elements. It's a pretty strong indication their hackers managed to get blueprints for this particular drone.

The blended body is suppose to be the most efficient aerodynamically. So if you were going strictly by aerodynamics this would be the shape you would see. The fact is that China is absolutely doing complete copies of other air frames, check out the J-15 its basically a part by part copy.
