China has called the Iran nuclear deal "irreplaceable" and the sole way to resolve the concerns over Tehran's nuclear program.
Foreign ministry spokesman Geng Shuang said on Tuesday that "the complete and effective implementation of the agreement is the only viable and effective way to settle the Iranian nuclear issue and ease tensions."
He said that Iran's commitment to the agreement should be dealt with by the joint commission that oversees it.
Geng also blamed the United States and Donald Trump for causing the current tensions — last year, the Trump administration pulled out of the deal and re-imposed economic sanctions on Tehran.
Geng said the U.S. should stop exerting pressure on Iran and create the conditions for a political and diplomatic settlement of the issue.
