US Ambassador to the United Nations, Nikki Haley, said late Wednesday the Trump administration's policy in Afghanistan was working, saying talks between the government and the Taliban are closer than ever before.

US President Donald Trump's Afghan plan involves shifting from a "time-based" approach to fighting America's longest war to emphasize linking US assistance to concrete results and cooperation from the Afghan government.

Haley said a weekend trip by the Security Council to Afghanistan was "great" because "we could see dramatic changes in terms of what the US policy has been doing," AP reported.

She said the US will work towards a peace process "with the goal being that we do not want Afghanistan to be a safe haven for terrorism anymore."

"We really are going to continue to work towards a peace process with the goal being that we do not want Afghanistan to be a safe haven for terrorism anymore. And so we continue to go down that path."

Asked whether a peace deal with the Taliban is one of the top priorities for the Trump administration, Haley said: "You know I think one of the top priorities for the administration is to make sure that we do everything we can to combat terrorism and in Afghanistan we know that has been a longtime safe haven for terrorism. So yes, we think peace is very important. We think the Taliban coming to the table is very important and we think that the entire international community needs to support this process so that we can have peace."

"The entire peace process is Afghan led and Afghan owned. And so what we have seen as they said since the US strategy went into place, they're starting to see the Taliban concede, they're starting to see them move towards coming to the table, and I think that we're going to let the Afghan government do that. We don't think that we need to facilitate the peace process. We think we need to support the peace process and they feel confident that the Taliban will be coming to the table and we think those negotiations will be very helpful."

AP also reported that Kairat Umarov, Kazakhstan Ambassador to the United Nations said council members expressed concern at intensified "terrorist activities."

"During the visit Security Council members noted concern with the persistence of insecurities especially with the intensification of terrorism activities in the north and east of Afghanistan and the regrouping of foreign terrorist fighters coming out of Syria and Iraq in Afghanistan. We urge the intensification of the peace and reconciliation knowing that the military solution can not be sufficient without the political process."
