Stronger dialogue over Iran nuclear deal urged

China called upon parties related to the Iran nuclear deal to exercise restraint and strengthen dialogue on Wednesday amid escalating tensions over the issue.

Noting that China commended Iran for strictly implementing the nuclear deal so far, Foreign Ministry spokesman Geng Shuang said at a daily news conference that China has been in close communication with Iran and other related parties.

Iranian President Hassan Rouhani said on Wednesday in letters to five world leaders that Iran will scale back its compliance with the 2015 nuclear agreement in 60 days unless they keep their promises on the deal.
