Recently the Australian Strategic Policy Institute put out a paper "The Chinese Communist Party: Engineering Global Consent" [1]. It focused on China's attempt to build a digital "belt road initiative" and the vast amounts of data (it was in the many hundreds of exabytes) they were collecting each year.

China has previously said 90% of military intelligence is OSINT, so this level of aggregation in a country without at least the checks and balances of the West is concerning. Think of all the problems America has. Then imagine them with Google 20x as big and no Supreme Court and no free press.
