China, Japan in fresh row over bullet trains
Beijing: China and Japan were involved in
a fresh row this time over the Intellectual Property Rights on
the high speed bullet trains.

"China`s high-speed rail technologies are much better
than those used by Japan`s Shinkansen Line," said Wang
Yongping, a spokesman of the Chinese Ministry of Railways.

The remarks by Wang today came after Japanese company
Kawasaki Heavy Industries Ltd threatened to take action if
China files for patents on high-speed trains made using
Japanese technologies.

"The Beijing-Shanghai high-speed railway and Japan`s
Shinkansen line cannot be mentioned in the same breath, as
many of the technological indicators used by China`s
high-speed railways are far better than those used in Japan`s
Shinkansen," Wang said, rejecting the Japanese accusation of
pirating.

"We Chinese will not claim technologies owned by
others as our own. And we will never give up our rights to
file patent applications for innovations developed through our
efforts and wisdom because of others` irresponsible remarks."

The China-developed CRH380A series trains, running
on the 1,318-km Beijing-Shanghai high-speed railway, are
different from the CRH2 trains, which were jointly
manufactured by China and Japan based on the imported
technologies from Kawasaki Heavy Industries,the ministry said.

Many of the technological indicators of the CRH380A
trains are better, with their power raised to 9,600 kw from
the CRH2 trains` 4,800 kw, speed increased to 380 kmph from
200-250 kmph and derailment coefficient lowered to 0.13 from
CRH2 trains` 0.73, official Xinhua news agency reported.

Wang said the IPR of China`s high-speed railways are
undoubtedly mastered by China itself.

The key technology regarding trains lies in the
relationship between the wheels and the rail, which is decided
by the bogie, or the driving wheel technology of railroad
transportation, he noted.

The bogie technology used in China`s high-speed
railways differs from those in other countries and is now
under China`s national patent protection, he said.
According to the ministry, more than 1,900 items of
technologies used in China`s high-speed railway have been
granted patents while the patent applications of 481 other
technologies are still under review.
