High-ranking American and Russian diplomats will meet on Monday in Geneva after Moscow laid down a list of demands for Washington and NATO.
Russia will then meet on Wednesday with all 30 NATO members -- the first such encounter since July 2019.
"That's why we tell our interlocutors repeatedly that it is very important to act with caution."
The Turkish minister also hit out at what he suggested was an "open or covert" arms embargo against Turkey by its NATO allies, without naming any country.
"The weakening of the Turkish armed forces means a weakening of NATO," he told reporters.
Before that in 2020, the United States hit Turkey's military procurement agency with sanctions over Ankara's controversial purchase of a Russian missile defence system.
Akar also said Ankara was ready to help the authorities in Kazakhstan, after protests in the ex-Soviet country over rising fuel prices erupted into widespread violence.
Turkey has sought closer ties with Turkic-speaking Central Asian states such as Kazakhstan since the Soviet Union's collapse in 1991.
"We're ready to give any kind of help and support to our Kazakh brothers and sisters, should we receive a request," Akar said.
"Kazakhstan is an important ally of ours. There must be peace and order as soon as possible," he added.
Kazakh President Kassym-Jomart Tokayev has already sought help from the Collective Security Treaty Organisation (CSTO), a military alliance of ex-Soviet states led by Russia.
It is not clear how many troops are being sent in the force -- which includes units from Russia, Belarus, Armenia, Tajikistan and Kyrgyzstan -- but media in Moscow have said the Russian contingent is expected to number less than 5,000.
