Shangri-la is the name of the cavernous, underground region below Tibet. Roerich and Ossendowski got information about that underground world on their trek across Tibet in the early 1900s. Apparently, there are underground tunnel systems from Tibet that go underneath the oceans to every continent, and what seem to be magnetic railways that travel across them at astounding speeds.
This would account for the undermining of western civilization. The undergrounders cultivate lackeys to do their bidding on the surface and cultivate and establish networks.
Does America seem infiltrated by China? Not exactly, the origin is Tibet, and Roosevelt's comment let the cat out of the bag when he answered a reporter's question by saying that the Doolittle raid had been launched from "Shangri-La".
All of the USA - China animosity is smoke and mirrors. China wants the USA and Russia to slug it out and then China will dominate when they both weaken each other.
