AIRLINERSChina's first commercial jet, the 90-seat ARJ21, hits the market next year, and a 190-seater is due by 2016. But experts say they're based on older McDonnell Douglas designs and that foreigners will supply the core systems.

SOLARChina makes 35% of the world's solar cells, but it suffers from massive overcapacity. And its strength is in an older technology using polysilicon, while the market is shifting to harder-to-make cells based on flexible materials.
