Russian Ambassador to Islamabad Alexey Dedov disclosed the details in an interview to state-run Pakistani radio.

This will be the third meeting of the "trilateral working group on Afghanistan," he said, following meetings in Beijing and Islamabad.

"What we see in Afghanistan, unfortunately, is worrisome because it does not bring us optimism. There is a lack of three crucial elements; that is a stable self-sufficient economy, good governance and strong army," observed Dedov.

A deterioration in security and the emergence of Islamic State affiliates in volatile border regions of Afghanistan have necessitated the trilateral consultations with an aim to form a "regional anti-terrorism structure" to counter "spillover effects" of terrorism, insist Pakistani, Russian and Chinese officials.
