President Hamid Karzai reacted furiously to the office being styled as a Taliban government-in-exile under the rebels' white flag and using the name of the "Islamic Emirate Of Afghanistan" from their hardline 1996-2001 regime.
The flag and the name were the focus of a diplomatic bust-up that derailed an early stage of efforts to foster a peace deal as the US-led NATO combat mission winds down 12 years after the Taliban were ousted after the 9/11 attacks.
"We were outraged ourselves because it was inconsistent with the assurances we had been given and the assurances we had given... We thought the Afghan reaction was both entirely predictable and entirely justified.
"The use of the Islamic Emirate title... (and) the symbols, signs and nomenclature were incompatible with what had been understood to be the arrangement.'
Dobbins, the US special representative to Afghanistan and Pakistan, spoke to reporters after meeting with Karzai in talks that he described as "very positive".
