BEIJING - China has lodged representations to the United States over the latest sanctions against Iran which involve Chinese companies and individuals.

Chinese Foreign Ministry spokesperson Lu Kang made the remarks at a routine press briefing Monday.

The United States on Friday announced sanctions on multiple entities and individuals involved in Iran's ballistic missile program and in providing support to a military force in Iran, including two Chinese companies and three individuals, according to reports.

"China always opposes any unilateral sanctions, especially when they harm the interests of a third party," Lu said, adding such sanctions are "not helpful" to promoting mutual trust and solving global issues.
