President Xi Jinping called for China's central Asian security partners at the Shanghai Cooperation Organization to take common steps block external efforts at destabilizing countries through "color revolutions" - a reference to a series of externally backed revolutions which have rocked Middle East and ex-Soviet satellite countries in recent years.

"We should prevent external forces from instigating a color revolution," Xi said in a Friday speech, offering as part of a potential initiative toward that end to train 2,000 police officers. These officers, he suggested, could be sent through a regional counterterrorism training center which will "strengthen law enforcement capacity building" which would help prevent destabilizing threats from outside.

He asked for countries represented at the conference to "guard against attempts by external forces to provoke a color revolution, and jointly oppose interference in other countries' internal affairs under any pretext."

He agreed with prior opening remarks of Vladimir Putin at the summit which emphasized a theme of declining US power as the unipolar world is disappearing. Xi said the regional SCO allies must stand together for a "just, democratic, multipolar world order based on international law and the central role of the UN, and not some rules that somebody invented and attempts to impose on others without even explaining what they are."
