[1] Hu Haifeng was the chairman of Nuctech, a Tsinghua University-owned company created in the late 1990s to make large scanners for shipping, trucking containers and railway cars, as well as luggage scanners and metal detectors for airports.

After Hu became chairman of the company, it was granted a near-monopoly by the central authorities on the lucrative market for selling security equipment to airports in China.

Chinese investment in airport security has risen sharply after the September 11 attacks.

In 2008, Hu Haifeng was promoted to Communist Party secretary of Tsinghua Holdings, which controls Nuctech and more than 20 other companies.

The company has been the focus for repeated allegations of unfair competition in the European Union, and also for corruption and abuse of office in the Philippines.
