China Warns US Retaliation Over Iran Sanctions Expansion
The United States has added new sanctions against Iran and some groups that trade with Iran.
Sanctions are penalties meant to make it harder for a country to do business.
China says the US is unfairly punishing companies and has warned it may respond.
China also says the sanctions do not have approval from the United Nations Security Council.
The US says the sanctions are designed to cut off Iran’s money and important supplies.
The new measures affect areas such as shipping, aviation, technology, gold and digital assets.
China buys much of Iran’s oil, so Chinese companies could be affected by future penalties.
More US action against Chinese banks could make relations between the two countries worse.
Iran’s economy minister said Iran expected the sanctions and predicted they would fail.
China warned it may take necessary measures against new US sanctions targeting Iran and related traders.
Beijing called the sanctions “illicit unilateral” measures lacking international-law or UN Security Council authorization.
The US sanctions target about 60 individuals, companies and vessels linked to Iran-related trade.
The measures cover Iran’s digital assets, technology, gold, aviation and shipping sectors.
China’s role as Iran’s largest oil customer could intensify tensions between Beijing and Washington.
