Countries that are members of the Collective Security Treaty Organization (a military-political international organization including Belarus, Armenia, Kazakhstan, Kyrgyzstan, Russia, and Tajikistan) are reluctant to participate in the war against Ukraine.
Despite Russia's insistence, the CSTO members do not want to decide on peacekeeping operations outside their countries. Including the territory of the so-called "DPR" and "LPR".
Instead, CSTO members may consider limited deployment of national contingents in Russia or Belarus. But only after the official statement about Ukraine's attack on their territory.
On April 15, Kazakhstan's Defense Minister Ruslan Zhaksylikov said that Kazakhstan had not received a request to send national troops to Ukraine. He confirmed that during the last meeting of the CSTO military committee, the issue of participation in the armed conflict on the territory of Ukraine was not considered.
Currently, all CSTO member states (except Russia and Belarus) are neutral on the Russian invasion. None of them recognized the annexation of Crimea and the independence of the DPR / LPR.
