BEIJING - The upcoming Shanghai Cooperation Organization (SCO) summit will issue a string of documents on expansion and a resolution marking the 70th anniversary of the end of WWII, a vice Chinese Foreign Minister said on Tuesday.

"The summit will define how the SCO will deal with threats and challenges in a new situation and come up with the specific measures on security and cooperation, significant to regional stability and development," Cheng Guoping said at a briefing on Tuesday.

The briefing came ahead of President Xi Jinping's attendance at the 14th meeting of the SCO Council of Heads of State on Thursday and Friday in Dushanbe, the capital of Tajikistan.

After the summit, Xi will pay state visits to Tajikistan, the Maldives, Sri Lanka and India.

Cheng called SCO "an important constructive force" in promoting regional peace and common prosperity over the past 13 years, since the organization's inception in 2001.

The SCO brings together China, Kazakhstan, Kyrgyzstan, Russia, Tajikistan and Uzbekistan with Afghanistan, India, Iran, Mongolia and Pakistan as observers, and Belarus, Turkey and Sri Lanka as dialogue partners.

Stressing the international and regional situation is undergoing complicated and profound changes, Cheng said the SCO expects agreements on peace and seeks common development. The summit will discuss regional security and economic cooperation. Leaders will exchange views on current international and regional issues of major concern.

Leaders will sign and issue the Dushanbe Declaration, approve a series of documents on SCO expansion and pass a resolution on the 70th anniversary of the end of WWII, Cheng said. An agreement on the facilitation of international highway transportation between SCO members is also likely.

During the summit, Xi will meet bilaterally or multilaterally with Russian President Vladimir Putin and other leaders, Cheng said.
