Since the first bullet train roared from Beijing to Tianjin in 2008, China's high-speed rail network has attracted world attention.

From importing key technology from abroad, China is now exporting its railway equipment, engineers and technologies to the rest of the world. China has begun building high-speed rail lines in Saudi Arabia, Venezuela and Turkey.

The State of California has signed a cooperation agreement with the Chinese government and General Electric to build bullet trains that will travel at 215 miles per hour. China is also looking for opportunities in seven other countries, notably a route sought by the Brazilian government between S?o Paulo and Rio de Janeiro.
