China on Saturday voiced its "strong dissatisfaction and firm opposition" to the United States' decision to impose sanction on a Chinese company, the Zhuhai Zhenrong Corp.

"As many other countries, China maintained normal cooperation with Iran in energy, economy and trade fields," Foreign Ministry spokesman Liu Weimin said when asked to comment on the sanction.

The United States attempted to internationalize its unilateral sanction measures against Iran, and to implement sanction against the Chinese company according to its domestic law, "which is groundless," Liu said.

Such a move is also not in line with the content and spirit of related resolutions on the Iran nuclear issue adopted by the United Nations Security Council, he said.
