Speaking to reporter at the White House, US President Donald Trump said that his meeting with Russian President Vladimir Putin is expected to take place "within two weeks or so, pretty quick," BBC News reports.

Trump added that the top diplomats from the US and Russia will determine where and when it will take place.

"I thought it was a very good phone call. Very productive," Trump said, about his call with Putin Thursday.

He added that he will meet Ukrainian President Volodymyr Zelenskyy Friday, and will update him on what was discussed with Putin.

"They don't get along well, those two," he says about Trump and Zelenskyy, adding that it could be "tough" to have them ever meet in person for diplomatic talks.

Trump went on to suggest that he would hold "separate but equal" meetings with each leader.

"This is a terrible relationship the two of them have," he said.

Trump went on to say that the discussion of Tomahawk missiles for Ukraine came up during the call with Putin.

"Tomahawks. We have a lot of them, but we need them. We can't deplete" US stockpiles, he said.

Also, he suggested that he joked about the US-produced missiles in his call with the Russian leader.

"I did actually say to him, 'Would you mind if I gave a couple of thousands of Tomahawks to your opposition?'. I did say that to him. I said it just like that. He didn't like that idea.

"You have to be a bit light-hearted sometimes."
