'Trump's out, Xi's in': BBC correspondents react to China's military parade

From massive, underwater torpedoes to state-of-the-art laser weapons that shoot down drones, China's latest military parade will now be broken down and analysed by Pentagon experts and defence officials around the world. The PLA has embarked on an extensive military modernisation programme that has seen it catching up - and in some areas - overtaking the United States. Hypersonic missiles that travel at more than five times the speed of sound is one area where China leads the world. Dr Sidharth Kaushal, a leading expert on missiles at the London think tank RUSI, highlights the YJ-17 - a hypersonic glide vehicle - and the YJ-19, a hypersonic cruise missile. China has also been investing heavily in artificial intelligence and autonomous weapons.
