China's cooperation with Iran is always conducted within the framework of international law and should not be interfered with or disrupted, Foreign Ministry spokesman Lin Jian said at a press briefing in Beijing on Tuesday.
Lin's remarks came after the U.S. threat of sanctions against Iran's trading partners.
"China's cooperation with Iran has always been conducted within the framework of international law and should not be interfered with and disrupted. China is closely watching the relevant development and will take all necessary measures to firmly safeguard its legitimate rights and interests," said Lin.
