On Monday, a Taliban spokesperson stated that the religious militia group will not be attending a peace conference tentatively planned for later this week in Turkey, jeopardising U.S. efforts to facilitate a practical peace plan.
Officials from the Biden Administration, the United States and Turkey stated that they intended to begin the conference on Friday, which was set to last around 10 days.
Ankara and Washington have been at odds over issues including Syria policy, human rights and the S-400 air defence acquisition, over which the United States has sanctioned Turkey and removed it from its F-35 fighter jet programme.
"On the S-400s, we reminded them once again why Turkey had to buy them, and repeated that Turkey had bought them and this is a done deal," Cavusoglu told.
"The United States won't force allies into an 'us-or-them' choice with China," Blinken, on his maiden voyage to Europe as Washington's top diplomat, will say at NATO headquarters.
"Countries can work with China where possible," he will say, noting that climate change was an area where cooperation was necessary.
The United States, Russia and other stakeholders however want to see some form of transitional government take power in Afghanistan, but Ghani has insisted leaders can only be chosen at the ballot box.
Allies are waiting anxiously for new US President Joe Biden to decide whether to stick to that date -- but Blinken said the US was still mulling it over.
U.S. Secretary of State Antony Blinken on Tuesday pledged to rebuild and revitalise the transatlantic military alliance after a bruising four years when Washington portrayed NATO as outdated, divided and in crisis.
The first top U.S. official to visit NATO since President Joe Biden took office in January, Blinken said the alliance was at a pivotal moment but could emerge stronger after internal disputes over Turkey and Russian gas.
"Secretary Blinken reiterated our commitment to supporting the defense of Saudi Arabia and strongly condemned recent attacks against Saudi territory from Iranian-aligned groups in the region," the department said in a statement, adding the two also discussed human rights and social and economic reforms in Saudi.
Last week saw the first ever summit of the leaders of the Quad, a four-way alliance of the US, Japan, Australia and India seen as a bulwark against China.
