China will host Iranian President Hassan Rouhani next month at a regional summit aimed at avoiding disruption of joint projects, its Foreign Ministry said Monday, as major powers scramble to save Iran's nuclear deal after the United States pulled out.

Rouhani will pay a working visit to China and attend the summit of the China and Russia-led security bloc the Shanghai Cooperation Organization (SCO), the ministry said.

It did not give exact dates for his visit, but the summit is scheduled to be held on the second weekend of June in the northern Chinese city of Qingdao.
