The flag of the Collective Security Treaty Organisation is the banner of the post-Soviet military alliance formed by treaty in 1992 and reorganised under its current name in 2002. The CSTO operates as a mutual-defence pact among its member states.
The design
The Flag of the Collective Security Treaty Organisation is a national emblem rendered in the colours and proportions defined by the country’s flag law. Its official aspect ratio is 2:3, the height-to-length ratio that fixes how the flag should be cut and flown. The colour scheme uses blue, white, with each shade specified to particular Pantone or RGB values for official reproduction.

Symbolism & heraldry
A blue field bearing a stylised emblem at centre: a globe view of the Eurasian landmass overlaid with the CSTO acronym, framed by olive branches. The design borrows the visual language of UN-style collective-security organisations — globe, olives, blue — but is consciously specific to the post-Soviet defence alliance it represents.
Heraldic elements on the Flag of the Collective Security Treaty Organisation — bands, charges, emblems or stars — each carry meaning agreed at the moment of the flag’s adoption. Re-readings happen across generations: a colour or a symbol that began with one meaning often picks up further layers as the country’s history unfolds.
Adoption & history
The current flag was adopted in 2002. It is credited to CSTO founding committee. Earlier banners flown by reflected the politics of their day; each redesign typically marked a moment of independence, regime change or constitutional reform. The current flag was chosen, debated and codified through the country’s official channels and is now protected by flag law.
Etiquette & protocol
The Flag of the Collective Security Treaty Organisation should be flown with respect: never allowed to touch the ground, never used as drapery for ceremonies it was not made for, and lowered or removed at sundown unless illuminated. When flown alongside other national flags, it takes precedence on home soil and is hoisted first and lowered last. On days of national mourning, the flag is flown at half-mast in line with directives from the head of state. These conventions are common to most nations and are usually written into the flag’s founding statute.
