(March 3): In just two decades, China sent people into space, built its own aircraft carrier and developed a stealth fighter jet.

Beijing’s blueprint for chip supremacy is enshrined in a five-year economic vision to be unveiled during a summit of top leaders in the capital this week. It’s a multi-layered strategy both pragmatic and ambitious in scope, embracing aspirations to replace pivotal US suppliers and fend off Washington, while molding homegrown champions in emergent technologies.
