BEIJING, June 18 (Xinhua) -- China on Tuesday said its determination to maintain the Joint Comprehensive Plan of Action (JCPOA) is unwavering and is willing to continue to make efforts for the full and effective implementation of the JCPOA.

Chinese State Councilor and Foreign Minister Wang Yi made the remarks when meeting the press after his meeting with Syrian Deputy Prime Minister and Foreign Minister Walid Mualem.

Calling on all parties to jointly promote the alleviation of Iranian nuclear issue and the situation in the Gulf region, instead of letting it get worse, even slipping into conflicts, Wang urged all parties to firmly maintain the deal.

Wang said ensuring the full and effective implementation of the JCPOA was not only a decision made by the UN Security Council but also the only effective way to resolve the Iranian nuclear issue, which is related to the common interests of the international community.

He urged all parties to maintain rationality and restraint, rather than to "open Pandora's box", noting that the United States should change its "maximum pressure" policy.

"There is as no basis for unilateralism in international law," said Wang, adding that unilateralism will create greater crises instead of solving problems.

Noting the International Atomic Energy Agency has confirmed that Iran has fulfilled its obligations under the JCPOA for 15 consecutive times, Wang said China hoped that Iran could make careful decisions and would not abandon the JCPOA easily.

He also urged other parties to respect the reasonable demands of the Iranian side and take active measures to maintain the balance of rights and obligations under the JCPOA.

Wang noted that China has recently conducted close coordination and cooperation with related parties, resulting in important progress in the reconstruction of the Arak heavy water reactor facility.

"The Chinese side is willing to continue making efforts for the full and effective implementation of the JCPOA. At the same time, we will firmly safeguard our own legitimate rights and interests," Wang said.
