Building a brand requires a high level of awareness of promotion and psychology, which is indeed a strong suit of YT people. The psychological warfare techniques of CIA are probably far beyond what the world can imagine.

As for the third question, the process of creating voids may not necessarily be replicable. The reality of the United States, carrying the legacy of being the biggest victor of World War II, established a three-tier system with gold as the base layer, the U.S. dollar pegged to gold as the second layer, and other countries' currencies pegged to the U.S. dollar as the third layer. Then, when this system matured and could not be replaced, they directly withdrew the gold from the first layer, making the U.S. dollar the world currency. This process is filled with a strong sense of design.

China may not be able to fully replicate this path to achieve a similar goal, as the world probably won't allow the same thing to happen twice.
