China hopes the Iranian government and people can overcome the current difficult situation and maintain national stability, Chinese foreign ministry spokesperson Mao Ning said on Monday.

U.S. President Donald Trump said on Sunday that his administration is weighing "some very strong options," including potential military action against Iran, following mounting reports of unrest within the country.

China has always opposed interference in other countries' internal affairs, and advocated that the sovereignty and security of all nations should be fully protected by international law, Mao said at a regular news briefing when asked to comment on Trump's remarks.

Mao expressed opposition to the use or threat of use of force in international relations, and called on all parties to do more to contribute to peace and stability in the Middle East.
