Trump’s secret China deal (Ad)

Trump just returned from Beijing with the most powerful business delegation in American history - Elon Musk, Jensen Huang, Tim Cook, and the CEOs of BlackRock, Goldman Sachs, and CitiBank. The media covered the handshakes. But what was really being negotiated behind closed doors? Porter Stansberry has connected the Beijing trip to a landmark pact signed by 13 nations in Washington - a pact designed to cut China out of a $3 trillion investment wave tied to the most critical resource of the 21st century. His new documentary exposes the five assets at the center of it all.tc pixel
