SEOUL, South Korea's presidential office on Wednesday announced a plan to hold top-level security consultations with Russia later this week, when North Korea's leader Kim Jong-un is scheduled to hold a summit with Russian President Vladimir Putin.

Chung Eui-yong, director of Cheong Wa Dae's National Security Office, is scheduled to meet with Nikolai Patrushev, secretary of the Security Council of the Russian Federation, in Seoul on Thursday, according to deputy presidential spokesperson Ko Min-jung.

The Russian official will also pay a courtesy call on President Moon Jae-in the same day, she added.

Ko would not elaborate on agenda items ahead of the talks between Chung and Patrushev, which she described as part of regular consultations between the two countries' presidential offices handling national security.

It would be the fifth meeting of its kind, with the previous session having been held in Moscow in June last year.

She did not reveal the Russian official's itinerary here either, including the dates of his arrival and departure.

South Korea is concerned about potential effects on regional security conditions from the upcoming summit between Pyongyang and Moscow.

North Korea's leader arrived in Russia by train on Thursday, with a plan to hold his first face-to-face talks with Putin in Vladivostok.
