Responding to a question about advice for Chinese tourists travelling to Iran, Mao said Beijing was “closely monitoring the development of the situation”.
“We will take all necessary measures to protect the safety of Chinese citizens,” she said.
Currently, China has not received reports of Chinese casualties in Iran.
The Chinese foreign ministry on Monday also reminded Chinese nationals to follow security developments and take necessary safety measures.
China hopes the Iranian government and people will overcome the current difficulties and uphold stability in the country, Mao said.
“China always opposes interference in other countries’ internal affairs, advocates that all countries’ sovereignty and security should be fully protected by international law, and opposes the use or threat of force in international relations,” she added.
“We call on parties to act in ways conducive to peace and stability in the Middle East.”
