Last year the Shanghai Cooperation Organization marked the 10th anniversary of its founding.During this relatively short period a considerable progress has been reached in carrying out cooperation in three major areas,i.e.security,economic cooperation,as well as the humanitarian "basket". Combating terrorism,separatism and extremism is a matter of special priority within the context of the SCO's task on ensuring regional stability and security.This is a solid and specific manifestation of SCO basic principles,the policy of gradual peaceful development of the region.1 In practical terms,the implementation of key documents such as the Shanghai Convention on combating terrorism,separatism and extremism,the Counterterrorism Convention,as well as triennial Cooperation Programmes on combating terrorism,separatism and extremism represents an unconditional priority for the SCO in the security field.The Regulations on political diplomatic measures and mechanisms of SCO response to events jeopardizing peace,security and stability in the region adopted in 2009,as well as its revised version being updated currently,are aimed at serving the same goal.
