In a statement, AMSC called on President Barack Obama's administration and Congress to re-evaluate the U.S. trade relationship with China.
"These criminal acts have led to significant financial harm to AMSC, its employees and their families as well as its shareholders. Over the past two years, more than 500 staff members worldwide have lost their jobs following Sinovel's egregious and unlawful behavior," AMSC Chief Executive Daniel McGahn said.
Sinovel was once AMSC's biggest customer, accounting for about 80 percent of its sales.
