China opposes U.S. Iran sanctions, creating new friction ahead of summit

China has publicly declared its strong opposition to the latest U.S. economic sanctions against Iran, positioning the move as a potential new point of contention in U.S.-China relations just weeks before a planned summit between the two countries' leaders.

China's Foreign Ministry spokesperson Lin Jian stated unequivocally at a press briefing that Beijing "firmly opposes illegal unilateral sanctions that lack a basis in international law and are not approved by the UN Security Council." He added, "Sanctions and pressure are not a solution to problems," and vowed that China would "take all necessary measures to firmly safeguard its legitimate rights and interests."

China has repeatedly made clear its position that it firmly opposes illegal unilateral sanctions that lack a basis in international law and are not approved by the UN Security Council.

The U.S. Treasury Department unveiled its "economic isolation operation" against Iran, designating over 60 entities involved in Iran's oil sector. However, in a move that appears to deliberately avoid immediate escalation with Beijing, Chinese financial institutions were not included in this round of sanctions. This suggests a strategic approach by the U.S. to pressure China into compliance regarding Iran, while leaving room for negotiation.

Sanctions and pressure are not a solution to problems, and China will take all necessary measures to firmly safeguard its legitimate rights and interests.

This situation presents a dilemma for the U.S. To achieve the full impact of its sanctions, it needs to pressure China, which imports a significant portion of Iran's oil (80-90%). However, intensifying pressure on China risks destabilizing the already fragile relationship between the two global powers. The recent trade war truce between the U.S. and China demonstrated a mutual desire to avoid full-scale economic conflict, but further U.S. sanctions could reignite trade tensions.

China has also signaled its continued engagement with Iran, with the Foreign Ministry revealing that Vice Minister Miao Deyu met with Iran's Deputy Foreign Minister Kazem Gharibabadi in Beijing on August 24 to discuss regional affairs. This meeting underscores China's intent to maintain its relationship with Iran, regardless of U.S. pressure. The upcoming summit between President Trump and President Xi Jinping will be a critical test of whether both nations can manage this escalating issue within the framework of "constructive strategic stability" they agreed upon, preventing the Iran sanctions from overshadowing broader bilateral relations.

Unless the U.S. measures become very broad or directly target China's core interests, the two sides will likely try to prevent the Iran issue from overwhelming the broader agenda.
