China has celebrated its Navy’s 70th anniversary with a parade off the coast of Qingdao.

Its fleet, including a 304 metre long aircraft carrier, was joined by ships from other nations to contribute to the parade, including our very own HMAS Melbourne.

"China's naval build-up and modernisation is unprecedented in both its ambition and speed,” says Adam Ni, a researcher with Macquarie University, who adds “by some estimates, China already has the biggest navy in the world by quantity.”
