Chen Jin had his eyes set on the space mining industry.
The earth's resources were limited, especially those scarce mineral resources. It would only take a few years of mining and they would be at the brink of exhaustion. The content of some elements in the earth's crust was only some ten or hundred thousand tons, which would make them even rarer than gold. For instance, the proven global reserves of a metal called Rhenium was only 2500 tons, but it yielded very high value when used as an industrial catalyst for the manufacture of aircraft engines and rocket engines.
