Chinese Legal System is mostly a joke with the communist party running the world’s most populated country with an iron hand. The courts are mostly for show as dissidence against the Party is not tolerated and human rights are non-existent.Also most of the major companies are run under crony capital rules rather than free markets. Most of the rulings are done which favor the ruling party mandarins with little respect to whatever Communist Party laws are. IP Theft has been a big problem for overseas companies operating in China with Google existing the country sometime ago after it was hacked. With the world’s largest Internet companies having to run because of IP theft, smaller companies have no chance.Sinovel is the biggest wind company in the world right now because of Chinese government support and policies. It commands huge influence in the corridors of power as it is unlikely to have become this big without major government and bank support.

American Superconductor (AMSC) which is one of the top rated wind stock in the US crashed by more than 40% as its largest customer AMSC is mainly a seller wind turbine core electrical components and full wind turbine electrical control systems (ECS).It has also made pilot sales of high capacity super conducting equipment to some customer like Tres Amigas.Sinovel which is also the 2nd biggest Wind Power Company in the world refused to take contracted shipments of wind turbine core electrical components and spare parts.The reason given was high inventory levels but the company failed to explain why Sinovel which is a multi billion dollar company has refused to pay AMSC for certain contracted shipments made in fiscal year 2010.Note $56 million in payments related to Fiscal 2010 quarters have been not paid to AMSC ( which would have been recognized as revenue).None of this was disclosed till now leading to a class action shareholder lawsuit against the company.It is quite perplexing why your largest customer will not pay you for past shipments and then cancel shipments as well.Is it because of some acrimony or is just Sinovel using its massive size to squash a small supplier.
