DOHA  - Afghan President Hamid Karzai was Saturday in Qatar to discuss Taliban militants opening an office in the Gulf state for peace negotiations that could end more than a decade of war.Karzai was welcomed at the airport by Qatari Minister of State for Foreign Affairs Abdullah al-Attiyah, the Gulf state’s official QNA news agency said, without giving any further details on his talks schedule. Until earlier this year, Karzai was opposed to the extremists having a meeting venue in Doha as he feared that his government would be frozen out of any negotiations.The militants refuse to have direct contact with Karzai, saying he is a puppet of the United States, which supported his rise to power after the military operation to oust the Taliban in 2001.But, with Nato-led combat troops due to withdraw from Afghanistan by the end of 2014, Karzai agreed to the proposed Taliban office in the Qatari capital Doha and is expected to firm up the plan with the emir of Qatar on Sunday.Any future peace talks still face numerous hurdles before they begin, including confusion over who would represent the Taliban and Karzai’s insistence that his appointees be at the centre of negotiations.“We will discuss the peace process, of course, and the opening of an office for the Taliban in Qatar,” presidential spokesman Aimal Faizi told AFP before Karzai left Kabul.“If we want to have talks to bring peace to Afghanistan, the main side must be the Afghan government’s representatives - the High Peace Council, which has members from all the country’s ethnic and political backgrounds,” Faizi added.A statement from Karzai’s office said he was accompanied on the two-day state visit by Foreign Minister Zalmai Rassoul and Salahuddin Rabbani, chairman of the High Peace Council.Negotiating with the hardline Taliban regime that had harboured Al-Qaeda before the 9/11 attacks was for many years anathema to countries fighting in the UN-backed coalition against the militants.But the search for a political settlement became a priority as the insurgency raged on with Taliban leaders able to fuel the violence from safe havens across the border in Pakistan.Kabul has repeatedly stressed that it will only start talks if the militants break all links with Al-Qaeda and give up violence, and Faizi said that any Taliban office in Qatar must be held to strict conditions.“It can only be an address where the armed opposition sit and talk to the Afghanistan government,” he said. “This office cannot be used for any other purposes.” The United Nations this week welcomed news that Karzai would visit Qatar, and issued another call for the Taliban to come to the negotiating table. “You are Afghans, you care, I assume, about your country, you care about (a) peaceful stable future of the country,” Jan Kubis, the UN envoy to Afghanistan, said.But the Qatar office could mean little if the Taliban refuse to negotiate with Karzai or the government-appointed High Peace Council.“The opening of the Taliban office in Qatar is not related to Karzai, it is a matter between the Taliban and the Qatar government,” Taliban spokesman Zabihullah Mujahid told AFP. “If Karzai visits, it is not our concern. Our representatives who are already in Qatar won’t see or talk to him.”
