Ukrainian President Volodymyr Zelensky, center, arrives at the 61st Munich Security Conference in Munich, Germany, on Friday.

Ukrainian President Volodymyr Zelensky has said that his conversation with US counterpart Donald Trump on Wednesday was long enough “to talk about some details,” but “not enough to make a plan.”

“We hear each other. We talked very positively. It was a really good conversation,” he told journalists at the Munich Security Conference on Friday. “We talked about the details of the situation at the front, what are the real losses.”

Zelensky said his figures on battlefield losses were different from Trump’s, but “the main thing is what we do next.”

Zelensky also said that he and Trump had spoken about the North Korean contingent fighting with the Russians in the Kursk region, where Ukrainian forces have taken several hundred square kilometers of Russian territory.

“We talked a lot about North Korea. About how many thousands there are, how many thousands have been killed… We also see now that there are several thousand, we think 2,000, maybe 2,500-3,000 (North Korean) soldiers will be transferred to the Kursk direction.”

Zelensky asserted that there were more than 4,000 North Korean casualties among the contingent previously sent, estimated at some 11,000 by Ukrainian officials.

“I think that the morale of the North Korean soldiers has deteriorated, because we see the number of people who have fled in one direction.

“I think these are important things for President Trump to hear – that they continue to have contacts with North Korea in terms of supplying military personnel, weapons, missiles,” Zelensky added.
