ISLAMABAD, PAKISTAN - Pakistan says that Russia-sponsored international talks on Afghanistan must involve the United States for bringing peace to the war-riven country, because Washington is the “biggest stakeholder” there.

Moscow plans to host this week (April 14) a new expanded round of multi-nation “consultations” it has recently launched with the stated goals of developing a “regional approach” for promoting Afghan security and a government-led national reconciliation with the Taliban.

But the U.S. administration has already refused to take part in the conference, questioning Russian intentions and motives.

Speaking to a local television station before the Moscow talks, the Pakistani prime minister’s foreign policy aide, Tariq Fatemi, stopped short of admitting the absence of Washington will not allow the multi-nation process to achieve its mission.

“They [U.S] have their troops present [in Afghanistan], they have invested one trillion dollars there, they are the biggest stakeholder, they have lost hundreds of their soldiers, so they have their interests there,” Fatemi explained.

While Afghanistan, Pakistan, Iran, China, India were represented in the last round of talks in Moscow earlier this year, former Soviet Central Asian states have been invited for the first time to attend the April 14 conference.

Pakistani prime minister’s foreign policy aide Syed Tariq Fatemi said Islamabad believes Russia is "positively" using its influence with the Taliban to encourage them to join peace talks.

“We hope and desire that when any such peace initiative will enter into a next stage, America will have to be made part of it,” Fatemi told Aaj TV when asked whether the Russian-initiated process could bring peace to Afghanistan without Washington.

Pakistan believes Russia is "positively" using its influence with the Taliban to encourage them to join peace talks and Islamabad is supportive of any such efforts, Fatemi insisted.

“Russia has told us its major concerns are that if civil war conditions are there in Afghanistan, it can become a center for terrorist organizations like Islamic State, or Daesh, who will then try to infiltrate into bordering Central Asian states,” the Pakistani official explained.

The Taliban's attacks on rival IS fighters in a bid to prevent them from establishing a foothold in the country apparently encouraged Russia to support the insurgent group. But Afghan President Ashraf Ghani on Sunday again warned Moscow against maintaining contacts with the Taliban.

"Anyone who thinks they can help themselves by helping the enemy of their enemy is mistaken. Anyone who thinks that they can differentiate between good and bad terrorism is mistaken," Ghani said.

Speaking at a news conference in Kabul, Ghani acknowledged Russia is also threatened by terrorism and sympathized with victims of recent terrorist attack in that country.

“We have an intense dialogue with all our interlocutors because a stable Afghanistan is to everybody’s benefit and unstable Afghanistan hurts everyone,” Ghani said when asked whether Kabul plans to attend Moscow talks on Friday. He added he wants Afghanistan “as a center of cooperation” in all efforts aimed at stabilizing his country.

The Russian foreign ministry, while regretting Washington’s refusal to attend the coming talks, had also underscored the United States is an “important player” in settling the Afghan conflict.

“So [the United States] joining the peacekeeping efforts of the countries of the region would help to reinforce the message to the Afghan armed opposition regarding the need to stop armed resistance and to start talks,” it maintained.

Meanwhile, Fatemi said Pakistan has also stepped up diplomatic efforts to ease tensions with Afghanistan and is seeking implementation of a proposed mechanism the two sides agreed to in talks last months that were mediated by Britain.

The mechanism, he explained, would allow establishment of a “channel of communication at different levels” between Islamabad and Kabul to help remove “any misunderstanding” and deal with any terrorist incident on either side of their shared border.

“Talks [between the two countries] at the Army level and at different other levels are currently underway, and at a final stage, if needed, foreign ministers of the two countries will also engage in frequent meetings,” Fatemi said.

Afghanistan and Pakistan each deny allegations they harbor and support anti-state militants engaged in terrorist attacks on their respective soils. Tensions have lately risen because of Islamabad’s unilateral border security measures to prevent terrorist infiltration.

Kabul disputes portions of the 2,600-kilometer border between the two countries and is opposed to fencing them, saying it will further add to problems facing divided families.
