A US-based company and its Canadian subsidiary today pleaded guilty to the charges of helping China develop a new attack helicopter and agreed to pay a penalty of $75 million as part of the settlement.
 
At a federal court hearing in Bridgeport, Connecticut, United Technologies and its two subsidiaries, Pratt & Whitney Canada and Hamilton Sundstrand Corp, pleaded guilty to violating Arms Export Control Act and making false statements in connection with its export to China of US-origin military software used in China's first modern military attack helicopter the Z-10.
 
In addition, they all agreed to pay more than $75 million as part of a global settlement with the Justice Department and State Department.
