The 3+3 format, that includes three Caucasian states of Armenia, Azerbaijan, and Georgia plus Iran, Russia, and Turkey held a meeting in Tehran on October 23. It was held at the level of foreign ministers. 

The meeting addressed the issues of the South Caucasus region, peace talks between Azerbaijan and Armenia, and the need to expand regional cooperation in political, economic, security, transit, and energy fields.

Armenian Prime Minister Nikol Pashinyan recently announced that he had agreed to hold a meeting within the 3+3 format as proposed by the President of Azerbaijan Ilham Aliyev.

The 3+3 format was established with the aim of resolving regional problems through the inclusion of regional countries and the exclusion of extra-regional and Western countries.

The first 3+3 meeting was held in Moscow last year at the level of deputy foreign ministers and without the presence of Georgia.
