This extends also to shipping, licensing, and auditing companies.
One example is https://www.pacificbasin.com/en/fleet/fleet.php
Somehow they’ve managed to assemble the worlds 2nd largest cargo fleet in terms of dry weight tonnage, all verifiable on https://marinetraffic.com btw, and yet they appear on NO LISTING ANYWHERE for the top 100 cargo companies.
That company is a front for the Chinese military, because if you do a reverse WHOIS search you will see http://pacbasin.com was also registered by the same organization...it is an autonomous drone hardware and extended flight operations firm. There is more to say there, but I will leave it at that.
