The Collective Security Treaty Organization (CSTO) has repeatedly proposed to establish cooperation with the NATO, including in such pressing issues as fight with the Afghan drug trafficking, counterterrorism, CSTO Secretary General Nikolay Bordyuzha told the Kazakhstan Today news agency.

"We expect Brussels to change attitude towards the CSTO after a change in leadership of the Alliance," Bordyuzha added.

According to Bordyuzha the organization is actively cooperating with the UN and has the appropriate contacts with the UN Counter-Terrorism Committee, the UN Office on Drugs and Crime and several other committees, working with the secretariat.
