BEIJING - This week's framework nuclear deal with Iran was also good for boosting relations between China and the United States, Chinese Foreign Minister Wang Yi said in a call with US Secretary of State John Kerry. The agreement can be attributed to all sides seizing a historic opportunity through concerted efforts, Wang told Kerry, China's foreign ministry said in a statement released late on Friday. "China and the United States, both taking on major responsibilities in safeguarding the international nuclear non-proliferation system, maintained good contact with each other during the negotiations, while instilling positive energy into bilateral relations," the statement cited Wang as saying. "In a bid to finalize a comprehensive deal as scheduled, China will maintain close coordination with all parties concerned, including the United States, and continue to play a constructive role during the process," Wang added. While China and the United States are at loggerheads over everything from cybersecurity to the value of China's yuan currency, the world's two largest economies also cooperate closely on certain international issues, including the Iranian and North Korean nuclear disputes.
