China backs Iran during US tensions

China offered strong support to Iran on Friday, with its top diplomat telling Iran's foreign minister that China opposes unilateral sanctions and supports Tehran's efforts to safeguard its interests. US-Iranian tensions have escalated in recent days, bringing increasing concerns about possible conflict. Iran has said it is committed to its obligations under an international nuclear deal despite the US withdrawal from the agreement last year, and has called the re-imposition of US sanctions unacceptable.
