The US President also said that he and Putin agreed to visit each other’s nations. He also said that he discussed Ukraine, the Middle East, energy, Artificial Intelligence, the power of the Dollar, among other subjects.

"President Putin even used my very strong Campaign motto of, ‘COMMON SENSE.’ We both believe very strongly in it. We agreed to work together, very closely, including visiting each other’s Nations," Trump said.

Meanwhile, Vladumir Putin told Trump that a 'long-term settlement' of Ukraine conflict is possible via peace talks, AFP reported quoting Kremlin spokesperson.

"President Putin ... agreed with Trump that a long-term settlement could be reached through peace negotiations," Putin spokesman Dmitry Peskov said. The Russian official said that the call between the two leaders lasted for around one-and-a-half hours.
