Top 10 most imported equipment in China

Silicon for integrated circuits, marine diesel engines, aviation engines, high-end medical equipment, chips, digital SLR cameras, photolithography, high-end CNC machine tools, high-end sensors, transmission electron microscopes, CNC cutting tools.

Silicon for integrated circuits requires high purity, diameter and impurity content of silicon materials, and China's vigorous development of the semiconductor industry, there is a great demand for raw materials, but their own silicon materials can not be broken through in a short time, only in 2017 China's total imports of integrated circuits reached 1.76 trillion yuan.

Aircraft engines are firmly controlled by the United States Pratt & Whitney, General Electric, the United Kingdom Rollo, and CMF 4, occupying 97% of the global market share.

Ships using diesel engines are basically MAN B&W diesel engine company and W?rtsil? company monopoly. China's development in this area is lagging behind, there are still large gaps with foreign countries, so the main imports.
