The Amazon Cooperation Treaty (ACT) was signed on 3 
July 1978 by Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname and 
Venezuela, aimed at promoting joint actions towards the harmonious development 
of the Amazon Basin. By that time, ACTO Member States undertook the shared 
commitment with environmental preservation and the rational use of the Amazonian 
natural resources. In 1995, the eight nations decided to create the ACTO, to 
strengthen and implement the Treaty goals. The amendment to the ACT was approved 
three years later, and the Permanent Secretariat was established in Brasilia in 
December 2002. ACTO is convinced that the Amazon region, for having one of the 
richest natural heritages in the world, plays a strategic role in inducing the 
upcoming development of the Amazon countries and region. It is a heritage that 
should be preserved but, above all, should be promoted pursuant to the 
principles of sustainable development.

Flag of ACTO is white with its emblem in center of flag. Emblem is a grey map 
of South American continent where Amazon Basin's area is indicated with a 
different (lighter) shade. Around the map, blue, red, yellow and green circles 
are placed. Dimension is ~5:8.

I discovered today that the OTCA Organización del Tratado de Cooperación 
Amazónica (Amazon Cooperation Treaty Organization) seems to have adopted a new 
(or variant?) flag. The flag reported at the top of this page is just the logo 
without words. This flag from the organization website shows a meeting on 28 
June 2017 with pictures of a meeting between WHO and OTCA showing the OTCA flag 
with the wording (only in Spanish) which was interesting as the organization has 
Guyana and Brazil as members.
Logo on white banner with the wording:
line 1.) OTCA 
line 2.) Organización del Tratado 
line 3.) de Cooperación 
Amazónica
