Ye's remarks are highly relevant as the situation is changing swiftly though the security situation is relatively stable in Central Asia.
"There has been an increase of violent regional tensions and terrorist activities," said Andre Kazantsev, director of the Analytical Center at Russia's Moscow Institute of International Relations.
He said the Islamic State group has recruited a large number of people from this economically uneven area and the possibility that terrorist activities will originate from Central Asian nations is on the rise.
"We are faced with increasingly heightened border stress, which could grow more grave in the future," said Yuri Tavrovsky, professor at People's Friendship University of Russia.
"Therefore, it is very necessary for us to enhance our coordination to combat terrorism and safeguard the security in Central Asia," Kazantsev said.
Mechanisms within the SCO have been created for joint anti-terrorism drills, securing international activities, intelligence exchanges, and joint work against cyber terrorism. But more coordination and cohesion are needed, said Zhang Xinfeng, director of the Executive Committee of the SCO's Regional Anti-Terrorism Agency.
Sun Zhuangzhi, secretary-general of the SCO Research Center at the Chinese Academy of Social Sciences, said that the SCO is also facing unconventional security threats.
"Securing food sources has become a priority for many Central Asian countries whose food supply relies heavily on imports," Sun said, adding that "nations such as Kazakhstan that are better off economically need to attach importance to financial security."
BROADER COOPERATION PROSPECT
Besides reviewing the memorandum of obligations for India and Pakistan to join the SCO at the Tashkent summit, the bloc might also add a few countries to the observation list, which, said Wang, is a step forward to elevate regional economic prosperity.
To promote common prosperity, SCO member countries have been aligning themselves with China's Belt and Road Initiative, which Chinese President Xi Jinping proposed in 2013 in a bid to boost connectivity and cooperation.
Some programs have already yielded results and some are still ongoing.
The Western Europe-Western China International Transit Corridor and the Uzbekistan-Turkmenistan-Iran-Oman transport corridor are under construction in order to rebuild the Silk Road and expand international transport, which would benefit some 3 billion people in countries along the ancient Silk Road.
When the China-Kyrgyzstan railway project is completed and put into operation, Kyrgyzstan will be able to connect its railway lines with those of Uzbekistan, Turkmenistan, Azerbaijan and even Europe, increasing regional interconnectivity.
Besides, SCO member states have also made headway in energy, transportation and telecommunication cooperation.
Now they plan to further tap the potential of economic cooperation within the SCO via implementing more strategic and pragmatic projects at the multilateral level.
In order to fund larger projects, Chinese Premier Li Keqiang, speaking at the SCO Prime Ministers' Meeting in the central Chinese city of Zhengzhou last December, called for a steady expansion of the SCO Interbank Consortium.
He also added that China would promote the Asian Infrastructure Investment Bank (AIIB) and the New Development Bank for BRICS to support SCO members' projects.
These measures are intended to fulfil China's pledge to build a community of common destiny in the region, a pledge fueled by the "Shanghai Spirit."
