China hopes the United States will show sincerity on the Iran nuclear issue, take actions as quickly as possible, including removing unjustified unilateral sanctions and lifting the "long-arm jurisdiction" on third-party entities and individuals, State Councilor and Foreign Minister Wang Yi said on Sunday.

At the same time, he said, Iran should resume compliance with the Iran nuclear deal and shoulder its responsibility of nuclear non-proliferation, Wang said.

The two countries can move forward in a step-by-step and reciprocal manner, he added.
