IPR fears 'won't shunt bullet train exports off track'

Fears over intellectual property rights will not derail China's exports of bullet trains, as the technology is home-grown, the vice-minister of science and technology said as he dismissed as "nonsense" copycat claims by a Japanese company.

The country had developed its own version of high-speed technology through years of innovation, Cao Jianlin said in an exclusive interview.

Cao also encouraged Chinese companies to file for patents overseas.
