China on Monday said it had "no difficulty in principle" with the release of Libya's frozen assets after the head of Libya's National Transitional Council (NTC) accused China of blocking the action.

"China has no difficulty in principle with the release of Libya's frozen assets," Chinese Foreign Ministry spokeswoman Jiang Yu said at a regular briefing on Monday.

"But in the spirit of being responsible to the Libyan people, China and some other members of the United Nations Security Council maintain that the use of assets and supervision mechanism be further specified," Jiang said.

Jiang's comments came days after NTC chief Mustafa Abdel Jalil said China was obstructing the release of Libya's frozen assets.

Some countries filed an application to the United Nations Security Council's Sanctions Committee to release the frozen assets of the Libya government.

"After some applicant countries submitted more information, the application was approved by the United Nations Security Council's Sanctions Committee," Jiang said.

Jiang said China has paid close attention to the humanitarian situation in Libya and offered humanitarian assistance since the outbreak of the Libyan crisis in February.

Jiang stressed China has been in touch with both sides in Libya during the crisis and played a positive part in promoting dialogue and seeking peace.
