A spokesman for the Chinese Railways Ministry says the nation's high-speed rail technologies are far superior to those used by Japan's bullet trains.
The remarks Thursday by Wang Yongping in an interview with the Xinhua news agency came after Kawasaki Heavy Industries Ltd. threatened to take action if China files for patents on high-speed trains that use Japanese technology in violation of contracts signed between Japan and China.
The technologies for which patent applications have reportedly been filed in at least five countries and regions are used in China's high-speed rail link between Beijing and Shanghai, which was inaugurated on June 30.
