"Don't worry too much about Chinese companies imitating you, they are creating value for you down the road," said Li Daokui, a leading Chinese economist at the Institute for New Economic Thinking's conference. Such "bandit innovators," he expanded, would eventually grow the market, leading to benefits for everybody.

Kawasaki Heavy Industries (KHI), maker of Japan's legendary Shinkansen bullet trains, bitterly disagrees. After signing technology transfers with CSR Sifang, the builder of China's impressive, new high-speed rail, KHI says it deeply regrets its now-dissolved partnership. It planned to sue its previously junior partner for patent infringement, but it backed down recently.

(...) What could drive the normally unlitigious Japanese into such a frenzy? Not only did China copy their technology, say the Japanese, after patenting remarkably similar high-speed-rail (HSR) tech, CSR now wants to sell it to the rest of the world -- as Chinese made. Both Japanese and European rail firms now find themselves frozen out and competing with their former Chinese collaborators for new contracts, inside and outside China.

With a diminishing domestic market, Japan's train industry is hoping to pick up orders abroad for its HSR. Before China stepped in, undercutting Japanese offers by about half, Japan looked very attractive to foreign buyers with its record for fast, reliable train systems.

This has probably been discussed before, but the INET conference in Hong Kong is recent.
