Xi noted that he exchanged in-depth views with Rouhani on the China-Iran relationship, as well as regional and international issues during the SCO summit in China's eastern port city of Qingdao last year, and they have reached important consensus.

China has always viewed its relations with Iran from a strategic and long-term perspective, Xi said, adding that despite changes in regional and international situations, China is willing to join hands with Iran in fostering a steady development of the China-Iran comprehensive strategic partnership.

Xi called on the two sides to strengthen strategic communication and support each other on issues concerning their respective core interests, adding that the two countries also need to step up coordination and properly conduct practical cooperation.

He also urged the two sides to enhance cooperation in such areas as anti-terrorism and combating cross-border crimes, and jointly clamp down the "three forces" of terrorism, separatism and extremism, including East Turkistan Islamic Movement.

China supports maintaining the Iran nuclear deal, said Xi, and is willing to step up coordination with Iran within such multilateral frameworks as the United Nations and the SCO to jointly safeguard basic norms of the international relations and multilateralism and preserve shared interests of developing countries, including China and Iran.

For his part, Rouhani said the Iran-China relationship carries a long-term and strategic significance.

He praised China's active role in the international affairs, and said his country is ready to strengthen communication and coordination with China.
