Australia's defence minister Richard Marles has called on China to explain why it needs to have "such an extraordinary military build-up".
On Sunday morning, Marles asserted that "what we have seen from China is the single biggest increase in military capability and build up in conventional sense, by any country since the end of the Second World War".
It is not just the size of the military build-up that concerns other countries, he told reporters.
"It's the fact that it is happening without strategic reassurance. It's happening without a clear strategic intent on the part of China… what we want to see is strategic transparency and strategic reassurance be provided by China, and an understanding of why it is needed to have such an extraordinary military build-up."
Those all have sources. There are also lots of reputable YouTubers with relevant academic credentials that have coved this, Asianometry and William C Fox are two that I recall covering the subject. I think Caspian Report did as well at one point in the last few years. This is like ultra basic surface level stuff everyone should know or severely question their sources and echo chambers if they are not made aware of this fundamental information.
