Tilting at windmills

China's corporate spying is a three-cornered problem

American prosecutors have targeted Chinese wind turbine maker Sinovel for allegedly stealing secrets from a US rival. The threat of a $4.8 billion fine for a company with total assets of $4.6 billion sounds potent. But it doesn't address the economic conditions that make China a target for accusations of ideas theft. Call it the corporate espionage triangle.

AMSC, a US-based wind company, claims that Sinovel stole source code to its software, and used it to soup up the Chinese company's own products. Sinovel had not responded to the charges by June 28. But AMSC's claims add fuel for politicians who argue a wider point: that when it comes to company dealings, China doesn't play by the rules.

Consider the "fraud triangle" outlined by criminologist Donald Cressey in the 1970s: at the three corners are pressure, rationalisation and opportunity. The combination enables people to commit fraud - or perhaps engage in corporate espionage.

As the economy slows, Chinese companies are under lots of pressure. For wind turbine makers, years of ramping up growth have created excess capacity and falling earnings. A fifth of the turbines built in China aren't attached to the electricity grid, according to Bloomberg New Energy Finance.

There's plenty of rationalisation, too. Chinese politicians paint the country as an economic underdog. British and Europeans pilfered the secrets of tea and porcelain from China centuries ago - which might make espionage look like an acceptable way to achieve growth. Large fines and arrests are hard to enforce across borders, so the perceived cost of getting caught may seem acceptably low.

Opportunities are also on the rise. Email and networks have increased the chances for governments and companies to purloin data. Companies can defend themselves with better controls over their people and systems - AMSC says that its secrets were sold on by one of its own employees. But technology makes companies with covetable ideas inherently vulnerable.

AMSC's battered shares rose over six per cent after the US Department of Justice launched its case against Sinovel. With the authorities on the case, the US. firm may have a hope of getting back some of its $800 million of estimated economic losses. But as China's economy decelerates, the triangle is likely to get sharper - and such cases will only become more common.
