Larijani made the remarks in a meeting with Chen Zhu, vice-chairperson of the Standing Committee of China National People's Congress (NPC), who is in Iran to attend the second edition of an international gathering of Parliament speakers from Afghanistan, Iran, Pakistan, Turkey, China and Russia on fight against terrorism and expansion of inter-regional ties.

Larijani said cooperation among Iran, China, Pakistan, Turkey, Russia and Afghanistan is very important for fighting terrorism.

On the need for protection of the JCPOA by other G5+1 after the US withdrawal from the international accord, Larijani said if the US violates and other members refuse to take any action, the JCPOA will have no benefit for Iran. So, the role of China, Russia and Europe to safeguard the nuclear accord is highly important, he added.

Referring to the role of China under present complicated regional and international conditions, he said fortunately, relations between Iran and China are at a high level and political consultations of the two countries in various levels show depth of their relations.

Meanwhile, the Chinese official said maintaining stability and strengthening commercial cooperation in the operation zone is important and Beijing hopes that in light of countries' efforts, the second edition of the international gathering of Parliament speakers from six countries will be held successfully.

Chen said regarding special regional and international conditions, China plans long-term relations with Iran and hopes that through cooperation with the Iranian party, its regional and international role will increase.

'China strives for maintaining the JCPOA because Iran has for years been the major trade partner of China and many cooperation MoUs reached between the two countries are in effect.'

He said China is interested in investment in various parts of Iranian economy and said China is present in different development projects and it will probe into problems with banking cooperation that has turned into a concern for Iran.

Chen added that Iranian and Chinese parliaments should have more cooperation to share experience, legislate, especially amend bilateral laws and sign more MoUs, taking practical action in that connection.

The second edition of an international gathering of Parliament speakers from Afghanistan, Iran, Pakistan, Turkey, China and Russia on fight against terrorism and expansion of inter-regional ties opened in Tehran on Friday and will officially be inaugurated on Saturday.

The first such a meeting was held in Pakistan last year. The presidency of the conference will be handed over to Iran from Pakistan in Tehran's meeting.

In the meeting, several issues will be discussed, including fight against terrorism, past experiences, current strategies, adoption of new and efficient regional approaches, expansion of communications, strengthening regional cooperation, and restoring peace and multilateral development in the region.
