TEHRAN, Iran (CNN) -- The presidents of Pakistan and neighboring Iran and Afghanistan have agreed that their foreign ministers will hold monthly meetings to discuss regional issues, according to a spokesman for Pakistani President Asif Ali Zardari.
Zardari, Afghan President Hamid Karzai, and Iranian President Mahmoud Ahmadinejad also decided Tuesday to hold quarterly meetings among themselves to discuss topics including terrorism, trade and development, Zardari spokesman Sarfraz Hussain told CNN.
The three leaders met in Tehran, where they plan to attend a summit Wednesday of the Economic Cooperation Organization -- a group of 10 nations, including Turkey and Kazakhstan, established in 1985.
The agenda and venue for the first foreign ministerial meeting would be announced Wednesday, Hussain said. There was no immediate comment from Iranian or Afghan officials.
