On June 30, 2011, a high-speed rail link between Beijing and Shanghai began commercial passenger services, having been completed in just three years. This news seems a great achievement by China.

However, in addition to the news report about Chinese train technology, another report has also caused irritation in Japan. The Chinese English newspaper China Daily reported on June 23 that CSR Corporation Limited, a state-owned Chinese railway-car manufacturer that makes the high-speed railway cars, is seeking patents in the US, Europe and other countries for its CRH380A train.

But because Bullet Train technology is known throughout the world as Japanese technology, Japan’s news media reported on the Chinese manufacturer’s patent-seeking activities immediately after the Chinese news report was received in Japan.
