I highly doubt VZ or Telia owns and provides a Big Expensive Router as CPE sitting on US landing
POP for a major international carrier.
More likely, thease routers are China Unicom's routers in their US POP, not managed by VZ/Telia.
The /30s in this case are unmanaged IP transit hand-offs, coming in as Nx10G or 100G. When your
IP transit provider assigns the /30, your router looks like it belongs to your upstream, common
mistake when interpreting traceroutes.
