SHANGHAI/TEHRAN -- Xi Jinping's pledge to help revive the stalled Iran nuclear deal is being cautiously welcomed by Washington, but observers warn that the Chinese leader's success could be "very limited" with Beijing-Tehran ties at a low ebb.
Xi made the comments on Tuesday, after meeting with Iranian President Ebrahim Raisi during his three-day official visit to Beijing, where the pair also agreed to beef up economic ties, with Iran hoping to persuade China to restart work on developing a major oil field near the Iraqi border.
