"We regret that the process is suspended. We still think that it is not dead but suspended. Emotions are running high, overboard on both sides, but we believe that at some point the sides will return and continue talking and finalising the deal", Kabulov, who is also the special presidential representative for Afghanistan, said.
Moscow saw the potential agreement as "an important step that would pave the way for national reconciliation and consequentlt the full settlement of the Afghan crisis", Kabulov said.
"So we expect that it will eventually happen", the diplomat said.
Trump said Monday, after calling off secret Camp David meetings with the Taliban and Afghan President Ashraf Ghani, that the talks with the movement were "dead".
Earlier in September, an explosion shook the area of Kabul where the US Embassy, local NATO headquarters, and government buildings are located.
The Taliban claimed responsibility for the blast, which killed, among other victims, two NATO personnel — one from the United States and another from Romania.
