As a result of cooperation by all sides, breakthrough has been achieved in the Iranian nuclear talks, which meets expectation by the International community, Kerry recalled.

He said that the United States hopes to further strengthen cooperation with all parties including China so as to eventually complete the Iranian nuclear talks.
