China says Iran nuclear pact must be upheld

Beijing: China on Wednesday called on all parties to uphold the Iranian nuclear pact after Tehran said it would end curbs on its uranium enrichment stockpile unless other powers helped it bypass renewed US sanctions.

"Maintaining and implementing the comprehensive agreement is the shared responsibility of all parties," said Chinese foreign ministry spokesman Geng Shuang at a regular press briefing.

"We call on all relevant parties to exercise restraint, strengthen dialogue, and avoid escalating tensions," he said, adding that China "resolutely opposes" unilateral US sanctions against Iran.
