Kim "will soon pay a visit to the Russian Federation at the invitation" of Putin, France24 reports referring to North Korea's official KCNA news service said.
North Korea's Kim to Meet Putin in Russia
The Kremlin said last week that the pair would meet in Russia "in the second half of April" but provided no further details.
They are expected to meet in the eastern Russian port of Vladivostok, possibly on Wednesday or Thursday.
It will be the first summit between the leaders of North Korea and Russia since Kim Jong Il -- the current leader's father -- met with Dmitry Medvedev eight years ago.
Russia has relatively warm ties with Pyongyang and provides some food aid, and Putin has long expressed his readiness to meet with the regime leader.
