Pakistan on Thursday hosted special representatives from China, the United States and Russia for the Troika Plus meeting to discuss the situation in Afghanistan, the Pakistani foreign office said.

The delegates are also expected to meet with Taliban interim foreign minister Amir Khan Muttaqi later on Thursday.

Pakistan's Foreign Minister Shah Mehmood Qureshi said Afghanistan is "at the brink of economic collapse," and the international community must urgently resume funding and provide humanitarian assistance.

Speaking at the opening of the meeting, Qureshi warned that any further downward slide would "severely limit" the new Taliban government's ability to run the country.

"It is, therefore, imperative for the international community to buttress provision of humanitarian assistance on an urgent basis," he said.

That included enabling Afghanistan to access funds frozen by Western donors since the Taliban took control of the country in August, he said.

Resuming the flow of funding "will dovetail into our efforts to regenerate economic activities and move the Afghan economy toward stability and sustainability," Qureshi said.
