J-20

China sent its most advanced fighter aircraft, the J-20, to patrol the East and South China Sea, on April 15. The move is believed to have created tensions among nations that share territorial issues with China. Reportedly, China's People's Liberation Army (PLA) has over 200 J-20 aircrafts in its fleet. According to experts, the J-20s are extremely advanced, stealthy and powerful just like the American aircrafts.
