BEIJING -- Poly Technologies Inc, a leading defense company in China, on Monday voiced strong objection to US sanctions on the firm and urged immediate corrections.

In a statement released right after the sanctions were announced on Monday, the firm said that it is absolutely groundless and unreasonable that the United States imposed the sanctions according to its own laws or regulations.

"We have never helped any countries or regions develop any banned weapons, nor have we exported or promised to export weapons or technologies to any countries or regions that are under United Nations Security Council Resolutions Sanctions," the firm said.

The Beijing-based firm, a subsidiary of state-owned giant China Poly Group Corporation, said that it has strictly observed China's laws and regulations as well as relative international laws and treaties.

"We hereby demands the U.S. side to respect the fact and immediately lift the sanctions," the firm said.
